• InstallShield 2010 with license - no license for automatic build system (CI) as Windows service

  - by Gilad

  I really need help here. We are using CI build-process (Hudson) as an automated build system using Msbuild. The CI run in Apache Tomcat 6 that run under the credentials of a domain user (not a local Windows user ). Every time the CI try to build an InstallShield project (using isproj files) we get a license error message: " C:\Program Files\MSBuild\InstallShield\2010\InstallShield.targets(62,3): error : -7159: The product license has expired or has not yet been initialized. You must launch the IDE to configure the product license in order to proceed. C:\Program Files\MSBuild\InstallShield\2010\InstallShield.targets(62,3): error : Exception Caught". If I log in to the same machine with the same domain user credentials and build the InstallShield project there is a license and it is working well. Adding the user to the local Users group doesn't help (no license). Adding the user to the local Administrators group helps and it is working. We do not want the user to be in the local Administrators group - for various reasons. What do I need to do to make it work? Do I need to add permissions to the use? Help will be highly appreciated.

• "The name 'WithTable' does not exist in the current context" using Fluent NHibernate

  - by Byron Sommardahl

  Might be a really easy problem to fix, but it the solution is eluding me! I'm using Fluent NHibernate 1.0 RTM (and using NHibernate bins that ships with it). I'm trying to map my entities and cannot use the WithTable() method. It's not available in Intelligence and VS doesn't suggest any namespaces to reference. Here's my code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using GeoCodeThe.Net.Domain.Entities; using FluentNHibernate.Mapping; namespace GeoCodeThe.Net.Domain.Mappings { class CategoryMap: ClassMap<ICategory> { public CategoryMap() { WithTable("Categories"); // <----- Compile error: The name 'WithTable' does not exist in the current context Id(x => x.Id); Map(x => x.Name); Map(x => x.Tags); } } My bin folder has: Antlr3.Runtime.dll Castle.Core.dll Castle.DynamicProxy2.dll FluentNHibernate.dll Iesi.Collections.dll log4net.dll NHibernate.ByteCode.Castle.dll NHibernate.dll FluentNHibernate.pdb Castle.Core.xml Castle.DynamicProxy2.xml FluentNHibernate.xml Iesi.Collections.xml log4net.xml NHibernate.ByteCode.Castle.xml NHibernate.xml Any clue what I'm missing? Let me know if you need any more clarification.

• Correct way to import Blueprint's ie.css via DotLess in a Spark view

  - by Chris F

  I am using the Spark View Engine for ASP.NET MVC2 and trying to use Blueprint CSS. The quick guide to Blueprint says to add links to the css files like so: <link rel="stylesheet" href="blueprint/screen.css" type="text/css" media="screen, projection"> <link rel="stylesheet" href="blueprint/print.css" type="text/css" media="print"> <!--[if lt IE 8]><link rel="stylesheet" href="blueprint/ie.css" type="text/css" media="screen, projection"><![endif]--> But I'm using DotLess and wish to simplify Blueprint as suggested here. So I'm doing this in my site.less (which gets compiled to site.min.css by Chirpy): @import "screen.css"; #header { #title { .span-10; .column; } } ... Now my site can just reference site.min.css and it includes blueprint's screen.css, which includes my reset. I can also tack on an @import "print.css" after my @import "screen.css" if desired. But now, I'm trying to figure out the best way to bring in the ie.css file to have Blueprint render correctly in IE6 & IE7. In my Spark setup, I have a partial called _Styles.spark that is brought into the Application.spark and is passed a view model that includes the filenames for all stylesheets to include (and an HtmlExtension to get the full path) and they're added using an "each" iterator. <link each="var styleSheet in Model.Styles" href="${Html.Stylesheet(styleSheet)}" rel="stylesheet" type="text/css" media="all"/> Should I simply put this below the above line in my _Styles.spark file? <!--[if lt IE 8]><link rel="stylesheet" href="${Html.Stylesheet("ie.css")}" type="text/css" media="screen, projection"><![endif]--> Will Spark even process it because it's surrounded by a comment?

• Exchange Web Services, try to use ExchangeImpersonationType ...

  - by howmanytimes

  I am trying to use EWS, first time trying to use the ExchangeServiceBinding. The code I am using is below: _service = new ExchangeServiceBinding(); //_service.Credentials = new NetworkCredential(userName, userPassword, this.Domain); _service.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials; _service.Url = this.ServiceURL; ExchangeImpersonationType ei = new ExchangeImpersonationType(); ConnectingSIDType sid = new ConnectingSIDType(); sid.PrimarySmtpAddress = this.ExchangeAccount; ei.ConnectingSID = sid; _service.ExchangeImpersonation = ei; The application is an aspnet 3.5 trying to create a task using EWS. I have tried to use impersonation because I will not know the logon user's domain password, so I thought impersonation would be the best fit. Any thoughts on how I can utilize impersonation? Am I setting this correctly, I get an error while trying to run my application. I also tried without impersonation just to try to see if I can create a task, no luck either. Any help would be appreciated. Thanks.

• Django: Validation error in Admin

  - by tomwolber

  NEWBIE ALERT! background: For the first time, I am writing a model that needs to be validated. I cannot have two Items that have overlapping "date ranges". I have everything working, except when I raise forms.ValidationError, I get the yellow screen of death (debug=true) or a 500 page (debug=false). My question: How can I have an error message show up in the Admin (like when you leave a required filed blank)? Sorry for my inexperience, please let me know if I can clarify the question better. Models.py from django.db import models from django import forms from django.forms import ModelForm from django.db.models import Q class Item(models.Model): name = models.CharField(max_length=500) slug = models.SlugField(unique=True) startDate = models.DateField("Start Date", unique="true") endDate = models.DateField("End Date") def save(self, *args, **kwargs): try: Item.objects.get(Q(startDate__range=(self.startDate,self.endDate))|Q(endDate__range=(self.startDate,self.endDate))|Q(startDate__lt=self.startDate,endDate__gt=self.endDate)) #check for validation, which may raise an Item.DoesNotExist error, excepted below #if the validation fails, raise this error: raise forms.ValidationError('Someone has already got that date, or somesuch error message') except Item.DoesNotExist: super(Item,self).save(*args,**kwargs) def __unicode__(self): return self.name def get_absolute_url(self): return "/adtest/%s/" % self.slug

• A couple of questions on exceptions/flow control and the application of custom exceptions

  - by dotnetdev

  1) Custom exceptions can help make your intentions clear. How can this be? The intention is to handle or log the exception, regardless of whether the type is built-in or custom. The main reason I use custom exceptions is to not use one exception type to cover the same problem in different contexts (eg parameter is null in system code which may be effect by an external factor and an empty shopping basket). However, the partition between system and business-domain code and using different exception types seems very obvious and not making the most of custom exceptions. Related to this, if custom exceptions cover the business exceptions, I could also get all the places which are sources for exceptions at the business domain level using "Find all references". Is it worth adding exceptions if you check the arguments in a method for being null, use them a few times, and then add the catch? Is it a realistic risk that an external factor or some other freak cause could cause the argument to be null after being checked anyway? 2) What does it mean when exceptions should not be used to control the flow of programs and why not? I assume this is like: if (exceptionVariable != null) { } Is it generally good practise to fill every variable in an exception object? As a developer, do you expect every possible variable to be filled by another coder?

• ASP.Net Entity Framework, objectcontext error

  - by Chris Klepeis

  I'm building a 4 layered ASP.Net web application. The layers are: Data Layer Entity Layer Business Layer UI Layer The entity layer has my data model classes and is built from my entity data model (edmx file) in the datalayer using T4 templates (POCO). The entity layer is referenced in all other layers. My data layer has a class called SourceKeyRepository which has a function like so: public IEnumerable<SourceKey> Get(SourceKey sk) { using (dmc = new DataModelContainer()) { var query = from SourceKey in dmc.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in query where SourceKey.sourceKey1 == sk.sourceKey1 select SourceKey; } return query; } } Lazy loading is disabled since I do not want my queries to run in other layers of this application. I'm receiving the following error when attempting to access the information in the UI layer: The ObjectContext instance has been disposed and can no longer be used for operations that require a connection. I'm sure this is because my DataModelContainer "dmc" was disposed. How can I return this IEnumerable object from my data layer so that it does not rely on the ObjectContext, but solely on the DataModel? Is there a way to limit lazy loading to only occur in the data layer?

• How can I pass an arbitrary object to jasper report as parameter?

  - by spderosso

  Hi, I would like to pass as a parameter to my .jrxml an arbitrary object of my domain, e.g a Person. InputStream reportFile = MyPage.this.getClass().getResourceAsStream("test.jrxml"); HashMap<String, Person> parameters = new HashMap<String, Person>(); parameters.put("person", new Person("John", "Doe")); ... JasperReport report = JasperCompileManager.compileReport(reportFile); JasperPrint print = JasperFillManager.fillReport(report, parameters, new JREmptyDataSource()); return JasperExportManager.exportReportToPdf(print); And on the .jrxml do something like: <?xml version="1.0" encoding="UTF-8"?> <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="test" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <parameter name="PERSON" isForPrompting="false" class="myApp.domain.person"/> <background> <band splitType="Stretch"/> </background> <title> <band height="20"> <staticText> <reportElement x="180" y="0" width="200" height="20"/> <text><![CDATA[$P{PERSON.lastName}]]></text> </staticText> </band> </title> ... Is something like this possible? Where can I find more complex tutorials that show more than just passing a java.lang.String? Thanks

• WCF NetTcpBinding Security - how does it work?

  - by RemotecUk

  Hi, encountered the following problems trying to work through the quagmire of settings in WCF... I created a WCF client server service using a NetTcp binding. I didn't make any changes to the security settings and when running on one machine it works very nicely. However, when I ran my client from another machine it complained that the server didnt like the security credentials that were sent. I understand now that NetTCP is "secured" by default and that my client would have been passing the wrong security details - namely the windows user name and password (or some form of domain authentication) to my server which as they are not running on the same domain it would not have liked. However, what I don't understand is as follows: I haven't specified any security in my binding - does the standard settings expect a windows user name or password to be sent? I don't have any certificate installed on my server - I understand that NetTCP bindings need some form of public private key to protect the credentials - yet this seemed to work when both client and server were on the same machine - how was the data getting encrypted? Or wants it as WCF knew it was on the same machine and encryption isn't needed? I have had to set my security mode on my client and server to "none" now and they connect nicely. However is there any way to encrypt my data without a certificate? Finally... what is the difference between Transport and Message security? To check my understanding (excuse the scenario!) message security is like if I sent a letter from person A to person B and I encode my hand writing to ensure that if anyone intercepts it they cannot read it? Transport Security is if I decide to have my letter sent by armed transport so that no one can get at it along the way? Is it possible to have any form of encryption in WCF without a certificate? My project is a private project and I dont want to purchase a certificate and the data isnt that sensitive anyway so its just for my own knowledge. Thanks in advance.

• long delay between serverside JSON and jqGrid loadComplete on asp.net mvc site

  - by ooo

  i have an asp.net mvc site where i load a jqgrid with json data public ActionResult GridData(GridData args) { IEnumerable<Application> applications = EntityModel.GetAll().ToList(); applications = FilterEntities(applications); if (args.sidx.IsNullOrEmpty() || args.sidx == "Id") { args.sidx = "Name"; args.sord = "asc"; } applications = applications.GridSort(args.sidx, args.sord); var paginatedData = applications.GridPaginate(args.page ?? 1, args.rows ?? 10, i => new { i.Id, Name = "<div class='showDescription' Id= '" + i.MyId + "'>" + i.Name + "</div>", MyId = string.Format("<a i.LastUpdated, i.LastUpdatedColumn }); return Json(paginatedData); } and here is my javascript code: function doInitCrudGrid(controller, names, model, editable, querystring) { jQuery("#grid").jqGrid({ mtype: 'POST', url: "/" + controller + "/GridData?" + querystring, datatype: "json", colNames: names, colModel: model, imgpath: "/Scripts/jqGrid/themes/steel/images", rowNum: 20, rowList: [10, 20, 50, 999], altRows: true, altclass: "altRow", jsonReader: { root: "Rows", page: "Page", total: "Total", records: "Records", repeatitems: false, id: "Id" }, pager: "#pager", height: "auto", sortname: "Id", viewrecords: true, sortorder: "desc", loadComplete: function() { alert("Load Complete"); }, ondblClickRow: function(rowid) { } }); i have a breakpoint on the return Json(paginatedData); line and that gets hit very quick but after that it takes about 10 seconds for the: alert("Load Complete"); and for the rendering to show up on the web page. Is there anyway to debug this or way to see why there would be this large delay between finishing the server side json and histting the loadcomplete on the javascript callback ?

• Try/Catch with jquery ajax request

  - by Anthony

  I am trying to build a Google Chrome extension that makes an ajax request. Something similar to the GMail Checker extension. The problem is that when I do the request using jquery, and I put in the wrong username/password, it fails silently, with the error callback function ignored. If I move the ajax call out of the background.html script (where I can't see the requests in the developer window), to the options.html script, I get a dialog box to re-authenticate. If I hit cancel, THEN the jquery error callback fires. But in the original model extension (again, the Gmail checker), they use plain (non-jquery) ajax calls with a try/catch, and if I put in the wrong credentials, I get an alert saying as much. I tried wrapping the entire jquery call in a try/catch, like so: try { $.ajax({ type: "POST", url: someurl, contentType : "text/xml", data: somedata, username: user, password: pass, success: function(data,status,xhr){ alert("Hurrah!"); }, error: function(xhr, status, error){ alert("Error!" + xhr.status); }, dataType: "xml" }); } catch(e) { alert("You messed something up!"); } But still nothing. Is the error due to it being asynchronous, or is Chrome not returning the request as an error since it wants to re-prompt for credentials? Or do I just not know how to use try/catch? Update Here is a very slimmed down version of how the model code does the request: var req = new XMLHttpRequest(); req.onreadystatechange = function() { try { if ( req.readyState == 4 ) { //Do some stuff with results } } catch (ex) { alert('Error parsing response.'); } } try { req.send (data); } catch (ex) { alert ('Something went wrong with the request.'); }

• EWS: RemoveExtendedProperty throws error when used on an occurrence of a recurring appointment

  - by flyfishnjake

  I am developing an application that syncs an exchange calendar to another calendar. I put extended properties on the exchange appointments in order to preserve the mapping between appointments in the two calendars. Everything is working fine until I try to remove an extended property from an occurrence of a recurring appointment. When I try doing this, I get the error: The delete action is not supported for this property. Here is a code snippet that demonstrates the error: public void ExchangeTest() { ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1) { Credentials = new NetworkCredential("username", "password", "domain") }; service.AutodiscoverUrl("[email protected]"); Appointment appt = new Appointment(service) { Recurrence = new Recurrence.DailyPattern(DateTime.Now, 2) { NumberOfOccurrences = 3}, Start = DateTime.Now, End = DateTime.Now.AddHours(2), Subject = "Test Appointment" }; NameResolutionCollection resolutionCollection = service.ResolveName("username", ResolveNameSearchLocation.DirectoryOnly, false); string mailboxAddress = resolutionCollection.First().Mailbox.Address; FolderId folderId = new FolderId(WellKnownFolderName.Calendar, mailboxAddress); appt.Save(folderId); PropertySet properties = new PropertySet(AppointmentSchema.ICalUid); appt.Load(properties); CalendarView view = new CalendarView(DateTime.Today, DateTime.Today.AddDays(8)){PropertySet = properties}; IEnumerable<Appointment> occurrences = service.FindAppointments(folderId, view) .Where(a => a.ICalUid == appt.ICalUid); ExtendedPropertyDefinition definition = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.PublicStrings, "TestProperty", MapiPropertyType.String); Appointment firstOccurrence = occurrences.First(); firstOccurrence.SetExtendedProperty(definition, "test"); firstOccurrence.Update(ConflictResolutionMode.AutoResolve); //The error occurs on the next line. firstOccurrence.RemoveExtendedProperty(definition); firstOccurrence.Update(ConflictResolutionMode.AutoResolve); //clean up appt.Delete(DeleteMode.HardDelete); } It appears that the error is only thrown for an Exchange 2007 server (It works on 2010). Am I doing something wrong, or is this a problem with Exchange? Is there a way to work around this issue? Any help will be appreciated.

• Codeigniter + TankAuth + Swfupload not able to get the logger user id

  - by Manny Calavera

  Hello. I am using Codeigniter with the TankAuth library installed and trying to upload to index.php/reuqests/doUpload from swfupload but can't access the page as authenticated. I have read many posts around the net about similar problem and tried to set $config['sess_match_useragent'] = FALSE; but still no difference. I have ended up skipping the login check in my controller for testing purposes. But now I need to access tankAuth library from my controller to get the current logged in user ID. It is requested in my application and cannot skip it, I really need to pass the logged in user id to that doUpload model. I have setup controller like this: function doUploadFileFn() { if (!$this->tank_auth->is_logged_in()) { return; } else { $user_id = $this->tank_auth->get_user_id(); $this->load->model('requests/doUploadFile'); $this->doUploadFile->uploadData($user_id); } } Now, it does not pass the is_logged_in() check, as I learned from other posts, CI deletes the session but I have setup the config not to match the user agent but still not working. Is there any solution to this out there ? Thank you.

• [Linq to SQL] Multiple foreign keys to the same table

  - by cdonner

  I have a reference table with all sorts of controlled value lookup data for gender, address type, contact type, etc. Many tables have multiple foreign keys to this reference table I also have many-to-many association tables that have two foreign keys to the same table. Unfortunately, when these tables are pulled into a Linq model and the DBML is generated, SQLMetal does not look at the names of the foreign key columns, or the names of the constraints, but only at the target table. So I end up with members called Reference1, Reference2, ... not very maintenance-friendly. Example: <Association Name="tb_reference_tb_account" Member="tb_reference" <====== ThisKey="shipping_preference_type_id" OtherKey="id" Type="tb_reference" IsForeignKey="true" /> <Association Name="tb_reference_tb_account1" Member="tb_reference1" <====== ThisKey="status_type_id" OtherKey="id" Type="tb_reference" IsForeignKey="true" /> I can go into the DBML and manually change the member names, of course, but this would mean I can no longer round-trip my database schema. This is not an option at the current stage of the model, which is still evolving. Splitting the reference table into n individual tables is also not desirable. I can probably write a script that runs against the XML after each generation and replaces the member name with something derived from ThisKey (since I adhere to a naming convention for these types of keys). Has anybody found a better solution to this problem?

• Django one form for two models

  - by martinthenext

  Hello! I have a ForeignKey relationship between TextPage and Paragraph and my goal is to make front-end TextPage creating/editing form as if it was in ModelAdmin with 'inlines': several field for the TextPage and then a couple of Paragraph instances stacked inline. The problem is that i have no idea about how to validate and save that: @login_required def textpage_add(request): profile = request.user.profile_set.all()[0] if not (profile.is_admin() or profile.is_editor()): raise Http404 PageFormSet = inlineformset_factory(TextPage, Paragraph, extra=5) if request.POST: try: textpageform = TextPageForm(request.POST) # formset = PageFormSet(request.POST) except forms.ValidationError as error: textpageform = TextPageForm() formset = PageFormSet() return render_to_response('textpages/manage.html', { 'formset' : formset, 'textpageform' : textpageform, 'error' : str(error), }, context_instance=RequestContext(request)) # Saving data if textpageform.is_valid() and formset.is_valid(): textpageform.save() formset.save() return HttpResponseRedirect(reverse(consults)) else: textpageform = TextPageForm() formset = PageFormSet() return render_to_response('textpages/manage.html', { 'formset' : formset, 'textpageform' : textpageform, }, context_instance=RequestContext(request)) I know I't a kind of code-monkey style to post code that you don't even expect to work but I wanted to show what I'm trying to accomplish.

• Sharepoint People Editor within Update Panel - Cannot set value after partial postback

  - by kalebd

  trying to set default value in the people picker with an update panel. On a test page without an update panel, the code PeopleEditor1.CommaSeparatedAccounts = "domain\\user.account"; works just fine. As soon as I add an update panel around that people editor the picker's text area gets cleared out and future calls to the above snippet are ignored. This can be reproduced by placing the following on a fresh aspx page w/ code-behind. code-behind: protected override void OnLoad(EventArgs e) { base.OnLoad(e); PeopleEditor1.CommaSeparatedAccounts = "domain\\user.account"; } aspx source: <asp:ScriptManager runat="server" id="ScriptMan"> </asp:ScriptManager> <asp:CheckBox runat="server" ID="causepostback" AutoPostBack="true" Text="Should this be checked?" /> <asp:UpdatePanel runat="server" ID="candypanel" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="causepostback" /> </Triggers> <ContentTemplate> <SharePoint:PeopleEditor runat="server" ID="PeopleEditor1" MultiSelect="true" AllowEmpty="false" SelectionSet="User,SecGroup,SPGroup" AutoPostBack="false" BorderWidth="1" Width="265px" PlaceButtonsUnderEntityEditor="false" Rows="1" /> </ContentTemplate> </asp:UpdatePanel> Your insight is appreciated.

• Putting JComboBox into JTable

  - by Dan

  Hi, I want to put individual JComboBoxes into each cells of a JTable. ie. The JComboBox content is not identical for each cell. I basically would like to be able to just call the following code to add a row of JComboBox into the JTable. Anyone has any idea? Thanks JComboBox cb1 = new JComboBox(...); JComboBox cb2 = new JComboBox(...); model.addRow(new Object[] {"Row name", cb1, cb2} ); JComboBox cb3 = new JComboBox(...); JComboBox cb4 = new JComboBox(...); model.addRow(new Object[] {"Row name 2", cb3, cb4} ); This is the resultant view if I do the above. http://www.freeimagehosting.net/uploads/a6292e08ee.png The closest example code I can find is as follows. But it is for where JComboBox content is identical for the individual column. Not the solution I need. TableColumn col = table.getColumnModel().getColumn(vColIndex); col.setCellEditor(new MyComboBoxEditor(values)); where public class MyComboBoxEditor extends DefaultCellEditor { public MyComboBoxEditor(String[] items) { super(new JComboBox(items)); } }

• How to perform a 301 redirect of all .php URLs to clean URLs?

  - by spacedatdusk

  My htaccess isn't quite working the way I want it to. I've seen some similar threads on here but they aren't quite what I need and I don't know enough yet about htaccess to modify the code to suit my needs. This is what I have working so far: I've got all non-www URLs redirecting to www URLs and I'm doing an internal rewrite of all URLs to the corresponding PHP file on the server. In the files I have relative links that are clean without any file extension on them. This is what I need to do yet: All the pages on my site are still accessible through URLs with .php on the end. For SEO reasons I want the URL's with .php to all do an external 301 redirect to the clean URL without the extension. Here's what I have in my htaccess file that's in the root folder on my server. Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php RewriteBase / RewriteCond %{HTTP_HOST} ^domain.com [NC] RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301] I'd appreciate any help. Thanks in advance!

• Rails Counter Cache and its implementation

  - by Ishu

  Hello All, I am trying to get hold of rails counter cache feature but not able to grasp it completely. Let's say that We have 3 models A B C A belongs to B or C depending upon a field key_type and key_id. key_type tells whether A belongs to B or C so if key_type="B" then the record belongs to B otherwise it belongs to C. In my model a.rb, I have defined following associations: belongs_to :b, :counter_cache => true, :foreign_key => "key_id" belongs_to :c, :counter_cache => true, :foreign_key => "key_id" and in b and c model files has_many :as , :conditions => {:key_type => "B"} has_many :as , :conditions => {:key_type => "C"} Both B and C Models have a column as as_count The problem is every time an object of a is created count is increased in the both the models b and c. Any help is appreciated. Initially i thought that this may work: belongs_to :b, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "B"} belongs_to :c, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "C"} But this does not help. Thanks

• Is it possible to store ObjectContext on the client when using WCF and Entity Framework?

  - by Sergey

  Hello, I have a WCF service which performs CRUD operation on my data model: Add, Get, Update and Delete. And I'm using Entity Framework for my data model. On the other side there is a client application which calls methods of the WCF service. For example I have a Customer class: [DataContract] public class Customer { public Guid CustomerId {get; set;} public string CustomerName {get; set;} } and WCF service defines this method: public void AddCustomer(Customer c) { MyEntities _entities = new MyEntities(); _entities.AddToCustomers(c); _entities.SaveChanges(); } and the client application passes objects to the WCF service: var customer = new Customer(){CustomerId = Guid.NewGuid, CustomerName="SomeName"}; MyService svc = new MyService(); svc.Add(customer); // or svc.Update(customer) for example But when I need to pass a great amount of objects to the WCF it could be a perfomance issue because of I need to create ObjectContext each time when I'm doing Add(), Update(), Get() or Delete(). What I'm thinking on is to keep ObjectContext on the client and pass ObjectContext to the wcf methods as additional parameter. Is it possible to create and keep ObjectContext on the client and don't recreate it for each operation? If it is not, how could speed up the passing of huge amount of data to the wcf service? Sergey

• Why isn't jQuery automatically appending the JSONP callback?

  - by Aseem Kishore

  The $.getJSON() documentation states: If the specified URL is on a remote server, the request is treated as JSONP instead. See the discussion of the jsonp data type in $.ajax() for more details. The $.ajax() documentation for the jsonp data type states (emphasis mine): Loads in a JSON block using JSONP. Will add an extra "?callback=?" to the end of your URL to specify the callback. So it seems that if I call $.getJSON() with a cross-domain URL, the extra "callback=?" parameter should automatically get added. (Other parts of the documentation support this interpretation.) However, I'm not seeing that behavior. If I don't add the "callback=?" explicitly, jQuery incorrectly makes an XMLHttpRequest (which returns null data since I can't read the response cross-domain). If I do add it explicitly, jQuery correctly makes a <script> request. Here's an example: var URL = "http://www.geonames.org/postalCodeLookupJSON" + "?postalcode=10504&country=US"; function alertResponse(data, status) { alert("data: " + data + ", status: " + status); } $.getJSON(URL, alertResponse); // alerts "data: null, status: success" $.getJSON(URL + "&callback=?", alertResponse); // alerts "data: [object Object], status: undefined" So what's going on? Am I misunderstanding the documentation or forgetting something? It goes without saying that this isn't a huge deal, but I'm creating a web API and I purposely set the callback parameter to "callback" in the hopes of tailoring it nicely to jQuery usage. Thanks!

• django-mptt fields showing up twice, breaking SQL

  - by Dominic Rodger

  I'm using django-mptt to manage a simple CMS, with a model called Page, which looks like this (most presumably irrelevant fields removed): class Page(mptt.Model, BaseModel): title = models.CharField(max_length = 20) slug = AutoSlugField(populate_from = 'title') contents = models.TextField() parent = models.ForeignKey('self', null=True, blank=True, related_name='children', help_text = u'The page this page lives under.') removed fields are called attachments, headline_image, nav_override, and published All works fine using SQLite, but when I use MySQL and try and add a Page using the admin (or using ModelForms and the save() method), I get this: ProgrammingError at /admin/mycms/page/add/ (1110, "Column 'level' specified twice") where the SQL generated is: 'INSERT INTO `kaleo_page` (`title`, `slug`, `contents`, `nav_override`, `parent_id`, `published`, `headline_image_id`, `lft`, `rght`, `tree_id`, `level`, `lft`, `rght`, `tree_id`, `level`) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)' for some reason I'm getting the django-mptt fields (lft, rght, tree_id and level) twice. It works in SQLite presumably because SQLite is more forgiving about what it accepts than MySQL. get_all_field_names() also shows them twice: >>> Page._meta.get_all_field_names() ['attachments', 'children', 'contents', 'headline_image', 'id', 'level', 'lft', 'nav_override', 'parent', 'published', 'rght', 'slug', 'title', 'tree_id'] Which is presumably why the SQL is bad. What could I have done that would result in those fields appearing twice in get_all_field_names()?

• LGPL and Dual Licensing Ajax Library

  - by Thomas Hansen

  Hi guys, I'm the previous founder of Gaiaware and Gaia Ajax Widgets and when I used to work there we had this rhetoric (which I have confirmed with some very smart FOSS people is correct) that when using a GPL Ajax library you're basically "distributing" the JavaScript which in turn makes the GPL viral clause kick in and forces people to purchase a proprietary license if they're going to build Closed Source stuff... So now I'm the the LGPL world here with Ra-Ajax which is an LGPL licensed library and I've got no intentions of creating a GPL licensed library since I believe strongly in that the LGPL is the "enabler" of the Open Web to prevail. But something interesting have happened which I think might still give me a "business model" here which is the Linking clause of the LGPL which I think goes something like this (pseudo); "If you link to an LGPL licensed thing you get no restrictions on your own derived works"... But so we started creating something we're calling Ajax Starter-Kits which effectively is a "Project Kickstarter" where you can download a finished project/solution which basically enables you to start out with some pre-done boiler plate code for problems such as Ajax DataGrids, Ajax Calendar Applications, Ajax TreeView Applications etc. And the funny thing is that our users would NOT "link" to these, they would effectively BE our users applications... So to wrap up my question. Would this force users of our LGPL licensed Ajax Starter-Kits to LGPL license their own work? Basically if it does we have a business model (and I get very happy) if not I'd just have to hope people would still like to pay us those $29 for our Starter-Kits to support the project... ;) Help rewarded with extreme gratitude...
