  • Change DIV contents on SELECT change

    - by Ian Batten
    I'm looking for a method of how to change the contents of a div when an option on a select dropdown is selected. I came across the following: <script type="text/javascript" src="jquery.js"></script> <!-- the select --> <select id="thechoices"> <option value="box1">Box 1</option> <option value="box2">Box 2</option> <option value="box3">Box 3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box1"><p>Box 1 stuff...</p></div> <div id="box2"><p>Box 2 stuff...</p></div> <div id="box3"><p>Box 3 stuff...</p></div> </div> <!-- the jQuery --> <script type="text/javascript" src="path/to/jquery.js"></script> <script type="text/javascript"> $("#thechoices").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices").change(); </script> This worked fine on it's own, but I want to use it with the following script: http://www.dynamicdrive.com/dynamicindex1/chainedmenu/index.htm When using it alongside this chainedmenu script, it just loads all of the DIV box contents at once, rather than each div option when a SELECT option is chosen. Any ideas on what I can use alongside this chainedmenu script to get different DIV contents to show for different SELECT options? Thanks in advance, Ian EDIT Here is a test page: http://freeflamingo.com/t/new.html

  • Django: Complex filter parameters or...?

    - by minder
    This question is connected to my other question but I changed the logic a bit. I have models like this: from django.contrib.auth.models import Group class Category(models.Model): (...) editors = ForeignKey(Group) class Entry(models.Model): (...) category = ForeignKey(Category) Now let's say User logs into admin panel and wants to change an Entry. How do I limit the list of Entries only to those, he has the right to edit? I mean: How can I list only those Entries which are assigned to a Category that in its "editors" field has one of the groups the User belongs to? What if User belongs to several groups? I still need to show all relevant Entries. I tried experimenting with changelist_view() and queryset() methods but this problem is a bit too complex for me. I'm also wondering if granular-permissions could help me with the task, but for now I have no clue. I came up only with this: First I get the list of all Groups the User belongs to. Then for each Group I get all connected Categories and then for each Category I get all Entries that belong to these Categories. Unfortunately I have no idea how to stitch everything together as filter() parameters to produce a nice single QuerySet.

  • Automatic linebreak in WPF label

    - by Vlad
    Dear all, is it possible for a WPF Label to split itself automatically into several lines? In my following example, the text is cropped at the right. <Window x:Class="..." xmlns="..." xmlns:x="..." Height="300" Width="300"> <Grid> <Label> `_Twas brillig, and the slithy toves did gyre and gimble in the wabe: all mimsy were the borogoves, and the mome raths outgrabe.</Label> </Grid> </Window> Am I doing something wrong? Taking other controls is unfortunately not a good option, since I need support of access keys. Replacing the Label with a TextBlock (having TextWrapping="Wrap"), and adjusting its control template to recognize access keys would be perhaps a solution, but isn't it an overkill? Edit: having a non-standard style for label will break skinning, so I would like to avoid it if possible.

  • javascript: detect if XP or Classic windows theme is enabled

    - by mkoryak
    Is there any way to detect which windows XP theme is in use? I suspect that there is no specific api call you can make, but you may be able to figure it out by checking something on some DOM element, ie feature detection. Another question: does the classic theme even exist on windows vista or windows 7? edit - this is my solution: function isXpTheme() { var rgb; var map = { "rgb(212,208,200)" : false, "rgb(236,233,216)" : true }; var $elem = $("<button>"); $elem.css("backgroundColor", "ButtonFace"); $("body").append($elem); var elem = $elem.get(0); if (document.defaultView && document.defaultView.getComputedStyle) { s = document.defaultView.getComputedStyle(elem, ""); rgb = s && s.getPropertyValue("background-color"); } else if (elem.currentStyle) { rgb = (function (el) { // get a rgb based color on IE var oRG =document.body.createTextRange(); oRG.moveToElementText(el); var iClr=oRG.queryCommandValue("BackColor"); return "rgb("+(iClr & 0xFF)+","+((iClr & 0xFF00)>>8)+","+ ((iClr & 0xFF0000)>>16)+")"; })(elem); } else if (elem.style["backgroundColor"]) { rgb = elem.style["backgroundColor"]; } else { rgb = null; } $elem.remove(); rgb = rgb.replace(/[ ]+/g,"") if(rgb){; return map[rgb]; } } Next step is to figure out what this function returns on non-xp machines and/or figure out how to detect windows boxes. I have tested this in windows XP only, so vista and windows 7 might give different color values, it should be easy to add though. Here is a demo page of this in action: http://programmingdrunk.com/current-projects/isXpTheme/

  • How do I get google protocol buffer messages over a socket connection without disconnecting the clie

    - by Dan
    Hi there, I'm attempting to send a .proto message from an iPhone application to a Java server via a socket connection. However so far I'm running into an issue when it comes to the server receiving the data; it only seems to process it after the client connection has been terminated. This points to me that the data is getting sent, but the server is keeping its inputstream open and waiting for more data. Would anyone know how I might go about solving this? The current code (or at least the relevant parts) is as follows: iPhone: Person *person = [[[[Person builder] setId:1] setName:@"Bob"] build]; RequestWrapper *request = [[[RequestWrapper builder] setPerson:person] build]; NSData *data = [request data]; AsyncSocket *socket = [[AsyncSocket alloc] initWithDelegate:self]; if (![socket connectToHost:@"192.168.0.6" onPort:6666 error:nil]){ [self updateLabel:@"Problem connecting to socket!"]; } else { [self updateLabel:@"Sending data to server..."]; [socket writeData:data withTimeout:-1 tag:0]; [self updateLabel:@"Data sent, disconnecting"]; //[socket disconnect]; } Java: try { RequestWrapper wrapper = RequestWrapper.parseFrom(socket.getInputStream()); Person person = wrapper.getPerson(); if (person != null) { System.out.println("Persons name is " + person.getName()); socket.close(); } On running this, it seems to hang on the line where the RequestWrapper is processing the inputStream. I did try replacing the socket writedata method with [request writeToOutputStream:[socket getCFWriteStream]]; Which I thought might work, however I get an error claiming that the "Protocol message contained an invalid tag (zero)". I'm fairly certain that it doesn't contain an invalid tag as the message works when sending it via the writedata method. Any help on the matter would be greatly appreciated! Cheers! Dan (EDIT: I should mention, I am using the metasyntactic gpb code; and the cocoaasyncsocket implementation)

  • How to use perl for SMTP connection with user and SSL Auth and send emails with attachment

    - by Octopus
    I am using a SMTP mail server which require user + ssl authentication for connection. I am looking for the perl modules to connect to the mail server and send emails but doesn't found anything helpful. Any suggestion for perl module or any perl code would be really appreciated.

  • How to best handle exception to repeating calendar events

    - by blcArmadillo
    I'm working on a project that will require me to implement a calendar. I'm trying to come up with a system that is very flexible: can handle repeating events, exceptions to repeats, etc. I've looked at the schema for applications like iCal, Lotus Notes, and Mozilla to get an idea of how to go about implementing such a system. Currently I'm having trouble deciding what is the best way to handle exceptions to repeating events. I've used databases quite a bit but don't have a ton of experience with really optimizing everything so I'm not sure which method of the two I'm considering would be optimal in terms of overall performance and ability to query/search: Breaking the repeating event. So taking the changing the ending date on the current row for the repeating event, inserting a new row with the exception, and adding another row continuing the old sequence. Simply adding an exception. So adding a new row with some field that indicates it as an override. So here is why I can't decide. Method one will result in a lot more rows since each edit requires 2 extra rows as apposed to only one row by the second method. On the other hand I think the query to find an event would be much simper, and thus possibly faster(?) using the first method. The second method seems like it will require more calculating on the application server since once you get the data you'll have to remove the intersection of the two rows. I know databases are often the bottleneck for websites and while I'm sure a lot of you are thinking either is fine because your project will probably never get large enough for the difference in efficiency to really matter, I'd still like to implement the best solution. So what method would you guys pick, or would you do something completely different? Also, as a side note I'll be using MySQL and PHP. If there is another technology that you think would be better suited for this, especially in the database area, please mention it. Thanks for the advice.

  • Kohana multi language website

    - by Sobek
    .I'm trying to set up a multi language website with kohana v3, following this tutorial: http://kerkness.ca/wiki/doku.php?id=example_of_a_multi-language_website Routing to a controller or action within i.e. website/controller/action seems to work as the url is properly redirected to website/lang/controller/action. However this is not working for ajax request calls. I have to manually edit the url with the appropriate language, to successfully retrieve the data. This also applies for anchors on the html page. In addition to this problem, the overflow parameter 'id' also doesn't work. It takes the 'lang' variable as its parameter. I have setup my default route just like in the tutorial i.e.: Route::set('default', '((<lang>)(/)(<controller>)(/<action>(/<id>)))', array('lang' => "({$langs_abr})",'id'=>'.+')) ->defaults(array('lang' => $default_lang,'controller' => welcome', 'action' => 'index')); Any help is much appreciated !

  • Transforming coordinates from an image control to the image source in WPF

    - by Gabriel
    I'm trying to learn WPF, so here's a simple question, I hope: I have a window that contains an Image element bound to a separate data object with user-configurable Stretch property <Image Name="imageCtrl" Source="{Binding MyImage}" Stretch="{Binding ImageStretch}" /> When the user moves the mouse over the image, I would like to determine the coordinates of the mouse with respect to the original image (before stretching/cropping that occurs when it is displayed in the control), and then do something with those coordinates (update the image). I know I can add an event-handler to the MouseMove event over the Image control, but I'm not sure how best to transform the coordinates: void imageCtrl_MouseMove(object sender, MouseEventArgs e) { Point locationInControl = e.GetPosition(imageCtrl); Point locationInImage = ??? updateImage(locationInImage); } Now I know I could compare the size of Source to the ActualSize of the control, and then switch on imageCtrl.Stretch to compute the scalars and offsets on X and Y, and do the transform myself. But WPF has all the information already, and this seems like functionality that might be built-in to the WPF libraries somewhere. So I'm wondering: is there a short and sweet solution? Or do I need to write this myself? EDIT I'm appending my current, not-so-short-and-sweet solution. Its not that bad, but I'd be somewhat suprised if WPF didn't provide this functionality automatically: Point ImgControlCoordsToPixelCoords(Point locInCtrl, double imgCtrlActualWidth, double imgCtrlActualHeight) { if (ImageStretch == Stretch.None) return locInCtrl; Size renderSize = new Size(imgCtrlActualWidth, imgCtrlActualHeight); Size sourceSize = bitmap.Size; double xZoom = renderSize.Width / sourceSize.Width; double yZoom = renderSize.Height / sourceSize.Height; if (ImageStretch == Stretch.Fill) return new Point(locInCtrl.X / xZoom, locInCtrl.Y / yZoom); double zoom; if (ImageStretch == Stretch.Uniform) zoom = Math.Min(xZoom, yZoom); else // (imageCtrl.Stretch == Stretch.UniformToFill) zoom = Math.Max(xZoom, yZoom); return new Point(locInCtrl.X / zoom, locInCtrl.Y / zoom); }

  • Django custom managers - how do I return only objects created by the logged-in user?

    - by Tom Tom
    I want to overwrite the custom objects model manager to only return objects a specific user created. Admin users should still return all objects using the objects model manager. Now I have found an approach that could work. They propose to create your own middleware looking like this: #### myproject/middleware/threadlocals.py try: from threading import local except ImportError: # Python 2.3 compatibility from django.utils._threading_local import local _thread_locals = local() def get_current_user(): return getattr(_thread_locals, 'user', None) class ThreadLocals(object): """Middleware that gets various objects from the request object and saves them in thread local storage.""" def process_request(self, request): _thread_locals.user = getattr(request, 'user', None) #### end And in the Custom manager you could call the get_current_user() method to return only objects a specific user created. class UserContactManager(models.Manager): def get_query_set(self): return super(UserContactManager, self).get_query_set().filter(creator=get_current_user()) Is this a good approach to this use-case? Will this work? Or is this like "using a sledgehammer to crack a nut" ? ;-) Just using: Contact.objects.filter(created_by= user) in each view doesn`t look very neat to me. EDIT Do not use this middleware approach !!! use the approach stated by Jack M. below After a while of testing this approach behaved pretty strange and with this approach you mix up a global-state with a current request. Use the approach presented below. It is really easy and no need to hack around with the middleware. create a custom manager in your model with a function that expects the current user or any other user as an input. #in your models.py class HourRecordManager(models.Manager): def for_user(self, user): return self.get_query_set().filter(created_by=user) class HourRecord(models.Model): #Managers objects = HourRecordManager() #in vour view you can call the manager like this and get returned only the objects from the currently logged-in user. hr_set = HourRecord.objects.for_user(request.user)

  • Getting web page after calling DownloadStringAsync()?

    - by OverTheRainbow
    Hello I don't know enough about VB.Net yet to use the richer HttpWebRequest class, so I figured I'd use the simpler WebClient class to download web pages asynchronously (to avoid freezing the UI). However, how can the asynchronous event handler actually return the web page to the calling routine? Imports System.Net Public Class Form1 Private Shared Sub DownloadStringCallback2(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) If e.Cancelled = False AndAlso e.Error Is Nothing Then Dim textString As String = CStr(e.Result) 'HERE : How to return textString to the calling routine? End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim client As WebClient = New WebClient() AddHandler client.DownloadStringCompleted, AddressOf DownloadStringCallback2 Dim uri As Uri = New Uri("http://www.google.com") client.DownloadStringAsync(uri) 'HERE : how to get web page back from callback function? End Sub End Class Thank you. Edit: I added a global, shared variable and a While/DoEvents/EndWhile, but there's got to be a cleaner way to do this :-/ Public Class Form1 Shared page As String Public Shared Sub AlertStringDownloaded(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) ' If the string request went as planned and wasn't cancelled: If e.Cancelled = False AndAlso e.Error Is Nothing Then page = CStr(e.Result) End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim wc As New WebClient AddHandler wc.DownloadStringCompleted, AddressOf AlertStringDownloaded page = Nothing wc.DownloadStringAsync(New Uri("http://www.google.com")) 'Better way to wait until page has been filled? While page Is Nothing Application.DoEvents() End While RichTextBox1.Text = page End Sub End Class

  • ASP.NET trace level

    - by axk
    This question is related to my another question. With trace enabled I can get the following(not quite verbose) trace of a page request: [2488] aspx.page: Begin PreInit [2488] aspx.page: End PreInit [2488] aspx.page: Begin Init [2488] aspx.page: End Init [2488] aspx.page: Begin InitComplete [2488] aspx.page: End InitComplete [2488] aspx.page: Begin PreLoad [2488] aspx.page: End PreLoad [2488] aspx.page: Begin Load [2488] aspx.page: End Load [2488] aspx.page: Begin LoadComplete [2488] aspx.page: End LoadComplete [2488] aspx.page: Begin PreRender [2488] aspx.page: End PreRender [2488] aspx.page: Begin PreRenderComplete [2488] aspx.page: End PreRenderComplete [2488] aspx.page: Begin SaveState [2488] aspx.page: End SaveState [2488] aspx.page: Begin SaveStateComplete [2488] aspx.page: End SaveStateComplete [2488] aspx.page: Begin Render [2488] aspx.page: End Render Reflector shows that System.Web.UI.Page.ProcessRequestMain method which I suppose does the main part of request processing has more conditional trace messges. For example: if (context.TraceIsEnabled) { this.Trace.Write("aspx.page", "Begin PreInit"); } if (EtwTrace.IsTraceEnabled(5, 4)) { EtwTrace.Trace(EtwTraceType.ETW_TYPE_PAGE_PRE_INIT_ENTER, this._context.WorkerRequest); } this.PerformPreInit(); if (EtwTrace.IsTraceEnabled(5, 4)) { EtwTrace.Trace(EtwTraceType.ETW_TYPE_PAGE_PRE_INIT_LEAVE, this._context.WorkerRequest); } if (context.TraceIsEnabled) { this.Trace.Write("aspx.page", "End PreInit"); } if (context.TraceIsEnabled) { this.Trace.Write("aspx.page", "Begin Init"); } if (EtwTrace.IsTraceEnabled(5, 4)) { EtwTrace.Trace(EtwTraceType.ETW_TYPE_PAGE_INIT_ENTER, this._context.WorkerRequest); } this.InitRecursive(null); So there are these EwtTrace.Trace messages which I don't see I the trace. Going deeper with Reflector shows that EtwTrace.IsTraceEnabled is checking if the appropriate tracelevel set: internal static bool IsTraceEnabled(int level, int flag) { return ((level < _traceLevel) && ((flag & _traceFlags) != 0)); } So the question is how do I control these _traceLevel and _traceFlags and where should these trace messages ( EtwTrace.Trace ) go? The code I'm looking at is of .net framework 2.0 @Edit: I guess I should start with ETW Tracing MSDN entry.

  • IE History Tracking, IFRAMES, and Cross Domain error...

    - by peiklk
    So here's the deal. We have a Flash application that is running within an HTML file. For one page we call a legacy reporting system in ASP.NET that is within an IFRAME. This page then communicates back to the Flash application using cross-domain scripting (document.domain = "domain" is set in both pages. THIS ALL WORKS. Now the kicker. Flash has history tracking enabled. This loads the history.js file that created a div tag to store page changes so the back and forward buttons work in the browser. Which works for Firefox and Chrome as they create a div tag. HOWEVER In Internet Explorer, history.js creates another IFRAME (instead of a DIV) called ie_historyFrame. When the ScriptResource.axd code attempts to access this with: var frameDoc = this._historyFrame.contentWindow.document; we get an "Access is Denied" error message. ARGH! We've tried getting a handle to this IFRAME and inserting the document.domain code. FAIL. We've tried editing the historytemplate.html file that flex also uses to include document.domain... FAIL. I've tried to edit the underlying ASP.NET page to disable history tracking in the ScriptManager control. FAIL. At my wit's end on this one. We have users who need to use IE to access this site. They are big clients who we cannot tell to just use Firefox. Any suggestions would be greatly appreciated.

  • File Format Conversion to TIFF. Some issues???

    - by Nains
    I'm having a proprietary image format SNG( a proprietary format) which is having a countinous array of Image data along with Image meta information in seperate HDR file. Now I need to convert this SNG format to a Standard TIFF 6.0 Format. So I studied the TIFF format i.e. about its Header, Image File Directories( IFD's) and Stripped Image Data. Now I have few concerns about this conversion. Please assist me. SNG Continous Data vs TIFF Stripped Data: Should I convert SNG Data to TIFF as a continous data in one Strip( data load/edit time problem?) OR make logical StripOffsets of the SNG Image data. SNG Data Header uses only necessary Meta Information, thus while converting the SNG to TIFF, some information can’t be retrieved such as NewSubFileType, Software Tag etc. So this raises a concern that after conversion whether any missing directory information such as NewSubFileType, Software Tag etc is necessary and sufficient condition for TIFF File. Encoding of each pixel component of RGB Sample in SNG data: Here each SNG Image Data Strip per Pixel component is encoded as: Out^[i] := round( LineBuffer^[i * 3] * **0.072169** + LineBuffer^[i * 3 + 1] * **0.715160** + LineBuffer^[i * 3+ 2]* **0.212671**); Only way I deduce from it is that each Pixel is represented with 3 RGB component and some coefficient is multiplied with each component to make the SNG Viewer work RGB color information of SNG Image Data. (Developer who earlier work on this left, now i am following the trace :)) Thus while converting this to TIFF, the decoding the same needs to be done. This raises a concern that the how RBG information in TIFF is produced, or better do we need this information?. Please assist...

  • PDFView printWithInfo:autoRotate: fails

    - by Brian Postow
    I'm trying to print a PDFDocument that I am constructing from a series of images. In case it matters, I'm doing all of this from within a Mozilla plugin. I create the PDFDocument, and put it into a PDFView, then I call [printView printWithInfo: [NSPrintInfo sharedPrintInfo] autoRotate: YES]; The print dialog comes up (as a separate window, instead of panel. I assume that that comes from being inside a mozilla window, so I wasn't too worried about it. The dialog shows my document, and I can page through it correctly, and everything looks good. However, when I hit "Print" the dropdown with "Layout" etc becomes empty, and the view under that becomes empty. The window doesn't disappear, and the document doesn't print. Hitting Cancel does exactly the same thing. The only thing I can do then is force-quit Mozillla. I based the program off of PDFKitLinker2 from the apple dev site, and that program works. But I can't see any significant differences between it and my version. Any suggestions on where to look? thanks. EDIT: Yes, I know that this is pretty much an exact duplicate of http://stackoverflow.com/questions/2058501/printing-off-screen-pdfviews but that never got a sufficient answer... (And I didn't notice it until just now...)

  • UI design in flash games

    - by anon
    This question is more UI/Design-ish than hard-core programming is. Background: I've been coding in VIM/C++/OpenGL for a long time. I've come to realize that this (VIM/C++/OpenGL) isn't the way to learn about programming fancy/cool-looking/futuristic UIs; and that the design of such UIs belongs more so in the artistic/designer world of Flash. Anyway, I currently have a machine with MacOSX. What software should I install? What book should I read to learn about the artistic/design side of these futuristic UIs? [It's okay if the tools to design them are mouse clicking + graphical rather than coding based]. Question: what software packages + books to read to learn about creating fancy-looking / futuristic UIs in flash? Thanks! EDIT: PS these questions seem to get closed frequently. If you're going to vote to close for "duplicate question"; atleast provide a link to the question (with an answer).

  • Is background tasks the solution for this problem?

    - by Trinca
    Hi. I need to develop an enterprise app that monitors the network traffic. Basically it detects if the user is in wi-fi or cellular data and save the amount of bytes was sent and received in a period of time. I saw an App at the AppStore that do exactly this job. Detecting wi-fi or cellular data is quite simple using the Reachability Sample provided by Apple. My problem is to keep monitoring the bytes sent and received while the app is in background. As it is an enterprise App, I used UIBackgroundModes "voip" to avoid the app to be terminated. I also installed the setKeepAliveTimeout method and I'm able to see the logs each 10 minutes, BUT only for 10 seconds after the method runs. I mean, setKeepAliveTimeout brings my App to run a Timer for 10 seconds each 1o minutes. I'm thinking wether or not a task in background is the best solution for my problem. I'll appreciate any comments. EDIT: Ok guys. Thats the perfect way to do it. First of all you must read this: http://www.christian-fries.de/blog/files/tag-ios.html I tried this and it works really fine. All we need to do is to create a second thread detached from the main one. This way we have a continuos threading running forever. You must see the GCD docs at Apple's website also. Second thing you should consider for an enterprise App is to set it up as a voip App, this way iOS will put your App running even after a reboot. It's a special behavior iOS has to keep voip Apps running. Thats it guys. I hope it can help you.

  • Equivalent of typedef in C#

    Is there a typedef equivalent in C#, or someway to get some sort of similar behaviour? I've done some googling, but everywhere I look seems to be negative. Currently I have a situation similar to the following: class GenericClass<T> { public event EventHandler<EventData> MyEvent; public class EventData : EventArgs { /* snip */ } // ... snip } Now, it doesn't take a rocket scientist to figure out that this can very quickly lead to alot of typing (appologies for the horrible pun) when trying to implement a handler for that event. It'd end up being something like this: GenericClass<int> gcInt = new GenericClass<int>; gcInt.MyEvent += new EventHandler<GenericClass<int>.EventData>(gcInt_MyEvent); // ... private void gcInt_MyEvent(object sender, GenericClass<int>.EventData e) { throw new NotImplementedException(); } Except, in my case, I was already using a complex type, not just an int. It'd be nice if it was possible to simplify this a little... Edit: ie. perhaps typedefing the EventHandler instead of needing to redefine it to get similar behaviour.

  • Axis2 webservice (aar archive) properties file

    - by XpiritO
    Hi there, guys. I'm currently developing a set of SOAP webservices over Axis2, deployed over a clustered WebLogic 10.3.2 environment. My webservices use some user settings that I want to be editable without the need for recompiling and regenerating the AAR archive. With this in mind, I chose to put them into a properties file that is loaded and consumed in runtime. Unfortunately, I'm having some questions about this: As far as I know, to achieve what I want, the only option is to put the properties file into the ../axis2/WEB-INF/classes directory of each one of the deployments (on each WebLogic instance) I currently have on my clustered configuration, and then load the file, as follows (or equivalent, this has not been verified for optimization): InputStreamReader fMainProp = new InputStreamReader(this.getClass().getResourceAsStream("myfile.properties")); Properties mainProp = new Properties(); mainProp.load(fMainProp); This is not as practical as I wanted it to be, because each time I want to alter some setting on the properties file, I have to edit each one of the files (deployed over different WebLogic instances) and there is a high probability of modifying one of these files without modifying the others. What I would like to know is if there is any (better) alternative to accomplish what I want, minimizing the potential conflict of configuration that is created by distributing and replicating the properties file through multiple WebLogic instances.

  • Prepopulating inlines based on the parent model in the Django Admin

    - by Alasdair
    I have two models, Event and Series, where each Event belongs to a Series. Most of the time, an Event's start_time is the same as its Series' default_time. Here's a stripped down version of the models. #models.py class Series(models.Model): name = models.CharField(max_length=50) default_time = models.TimeField() class Event(models.Model): name = models.CharField(max_length=50) date = models.DateField() start_time = models.TimeField() series = models.ForeignKey(Series) I use inlines in the admin application, so that I can edit all the Events for a Series at once. If a series has already been created, I want to prepopulate the start_time for each inline Event with the Series' default_time. So far, I have created a model admin form for Event, and used the initial option to prepopulate the time field with a fixed time. #admin.py ... import datetime class OEventInlineAdminForm(forms.ModelForm): start_time = forms.TimeField(initial=datetime.time(18,30,00)) class Meta: model = OEvent class EventInline(admin.TabularInline): form = EventInlineAdminForm model = Event class SeriesAdmin(admin.ModelAdmin): inlines = [EventInline,] I am not sure how to proceed from here. Is it possible to extend the code, so that the initial value for the start_time field is the Series' default_time?

  • Django: Using 2 different AdminSite instances with different models registered

    - by omat
    Apart from the usual admin, I want to create a limited admin for non-staff users. This admin site will have different registered ModelAdmins. I created a folder /useradmin/ in my project directory and similar to contrib/admin/_init_.py I added an autodiscover() which will register models defined in useradmin.py modules instead of admin.py: # useradmin/__init__.py def autodiscover(): # Same as admin.autodiscover() but registers useradmin.py modules ... for app in settings.INSTALLED_APPS: mod = import_module(app) try: before_import_registry = copy.copy(site._registry) import_module('%s.useradmin' % app) except: site._registry = before_import_registry if module_has_submodule(mod, 'useradmin'): raise I also cretated sites.py under useradmin/ to override AdminSite similar to contrib/admin/sites: # useradmin/sites.py class UserAdminSite(AdminSite): def has_permission(self, request): # Don't care if the user is staff return request.user.is_active def login(self, request): # Do the login stuff but don't care if the user is staff if request.user.is_authenticated(): ... else: ... site = UserAdminSite(name='useradmin') In the project's URLs: # urls.py from django.contrib import admin import useradmin admin.autodiscover() useradmin.autodiscover() urlpatterns = patterns('', (r'^admin/', include(admin.site.urls)), (r'^useradmin/', include(useradmin.site.urls)), ) And I try to register different models in admin.py and useradmin.py modules under app directories: # products/useradmin.py import useradmin class ProductAdmin(useradmin.ModelAdmin): pass useradmin.site.register(Product, ProductAdmin) But when registering models in useradmin.py like useradmin.site.register(Product, ProductAdmin), I get 'module' object has no attribute 'ModelAdmin' exception. Though when I try this via shell; import useradmin from useradmin import ModelAdmin does not raise any exception. Any ideas what might be wrong? Edit: I tried going the @Luke way and arranged the code as follows as minimal as possible: (file paths are relative to the project root) # admin.py from django.contrib.admin import autodiscover from django.contrib.admin.sites import AdminSite user_site = AdminSite(name='useradmin') # urls.py (does not even have url patterns; just calls autodiscover()) import admin admin.autodiscover() # products/admin.py import admin from products.models import Product admin.user_site.register(Product) As a result I get an AttributeError: 'module' object has no attribute 'user_site' when admin.user_site.register(Product) in products/admin.py is called. Any ideas? Solution: I don't know if there are better ways but, renaming the admin.py in the project root to useradmin.py and updating the imports accordingly resolved the last case, which was a naming and import conflict.

  • URL Encoding using C#

    - by masfenix
    I have an application which I've developed for a friend. It sends a POST request to the VB forum software and logs someone in (with out setting cookies or anything). Once the user is logged in I create a variable that creates a path on their local machine. c:\tempfolder\date\username The problem is that some usernames are throwing "Illegal chars" exception. For example if my username was mas|fenix it would throw an exception.. Path.Combine( _ Environment.GetFolderPath(System.Environment.SpecialFolder.CommonApplicationData), _ DateTime.Now.ToString("ddMMyyhhmm") + "-" + form1.username) I don't want to remove it from the string, but a folder with their username is created through FTP on a server. And this leads to my second question. If I am creating a folder on the server can I leave the "illegal chars" in? I only ask this because the server is Linux based, and I am not sure if Linux accepts it or not.. EDIT: It seems that URL encode is NOT what I want.. Here's what I want to do: old username = mas|fenix new username = mas%xxfenix Where %xx is the ASCII value or any other value that would easily identify the character.

  • Javascript Post Request like a Form Submit

    - by Joseph Holsten
    I'm trying to direct a browser to a different page. If I wanted a GET request, I might say document.location.href = 'http://example.com/q=a'; But the resource I'm trying to access won't respond properly unless I use a POST request. If this were not dynamically generated, I might use the HTML <form action="http://example.com/" method="POST"> <input type="hidden" name="q" value="a"> </form> Then I would just submit the form from the DOM. But really I would like JavaScript that allows me to say post_to_url('http://example.com/', {'q':'a'}); What's the best cross browser implementation? Edit I'm sorry I was not clear. I need a solution that changes the location of the browser, just like submitting a form. If this is possible with XMLHTTPRequest, it is not obvious. And this should not be asynchronous, nor use XML, so AJAX is not the answer.

  • SQL Server PIVOT with multiple X-axis columns

    - by HeavenCore
    Take the following example data: Payroll Forname Surname Month Year Amount 0000001 James Bond 3 2011 144.00 0000001 James Bond 6 2012 672.00 0000001 James Bond 7 2012 240.00 0000001 James Bond 8 2012 1744.50 0000002 Elvis Presley 3 2011 1491.00 0000002 Elvis Presley 6 2012 189.00 0000002 Elvis Presley 7 2012 1816.50 0000002 Elvis Presley 8 2012 1383.00 How would i PIVOT this on the Year + Month (eg: 201210) but preserve Payroll, Forename & Surname as seperate columns, for example, the above would become: Payroll Forename Surname 201103 201206 201207 201208 0000001 James Bond 144.00 672.00 240.00 1744.50 0000002 Elvis Presley 1491.00 189.00 1816.50 1383.00 I'm assuming that because the Year + Month names can change then i will need to employ dynamic SQL + PIVOT - i had a go but couldnt even get the code to parse, nevermind run - any help would be most appreciated! Edit: What i have so far: INSERT INTO #tbl_RawDateBuffer ( PayrollNumber , Surname , Forename , [Month] , [Year] , AmountPayable ) SELECT PayrollNumber , Surname , Forename , [Month] , [Year] , AmountPayable FROM RawData WHERE [Max] > 1500 DECLARE @Columns AS NVARCHAR(MAX) DECLARE @StrSQL AS NVARCHAR(MAX) SET @Columns = STUFF((SELECT DISTINCT ',' + QUOTENAME(CONVERT(VARCHAR(4), c.[Year]) + RIGHT('00' + CONVERT(VARCHAR(2), c.[Month]), 2)) FROM #tbl_RawDateBuffer c FOR XML PATH('') , TYPE ).value('.', 'NVARCHAR(MAX)'), 1, 1, '') SET @StrSQL = 'SELECT PayrollNumber, ' + @Columns + ' from ( select PayrollNumber , CONVERT(VARCHAR(4), [Year]) + RIGHT(''00'' + CONVERT(VARCHAR(2), [Month]), 2) dt from #tbl_RawDateBuffer ) x pivot ( sum(AmountPayable) for dt in (' + @Columns + ') ) p ' EXECUTE(@StrSQL) DROP TABLE #tbl_RawDateBuffer
