    Hi, I new in Zend. Main Question: Is this code good for user login (Its beginning- because that I want to know if its can be improve)? Code understanding question: Is every time that in action call to his view- code execution in action not going to next row until view request?

  • reddit style voting with django

    - by dotty
    Hay i need to hand implemeneting a voting system into a model. I've had a huge helping hand from Mike DeSimone making this work in the first place, but i need to expand upon his work. Here is my current code View def show_game(request): game = Game.objects.get(pk=1) discussions = game.gamediscussion_set.filter(reply_to=None) d = { 'game':game, 'discussions':discussions } return render_to_response('show_game', d) Template <ul> {% for discussion in discussions %} {{ discussion.html }} {% endfor %} </ul> Model class GameDiscussion(models.Model): game = models.ForeignKey(Game) message = models.TextField() reply_to = models.ForeignKey('self', related_name='replies', null=True, blank=True) created_on = models.DateTimeField(blank=True, auto_now_add=True) userUpVotes = models.ManyToManyField(User, blank=True, related_name='threadUpVotes') userDownVotes = models.ManyToManyField(User, blank=True, related_name='threadDownVotes') def html(self): DiscussionTemplate = loader.get_template("inclusions/discussionTemplate") return DiscussionTemplate.render(Context({ 'discussion': self, 'replies': [reply.html() for reply in self.replies.all()] })) DiscussionTemplate <li> {{ discussion.message }} {% if replies %} <ul> {% for reply in replies %} {{ reply }} {% endfor %} </ul> {% endif %} </li> As you can see we have 2 fields userUpVotes and userDownVotes on the model, these will calculate how to order the discussions and replies. How would i implement these 2 fields to order the replies and discussions based on votes? Any help would be great!

  • Testing Finite State Machines

    - by Pondidum
    I have inherited a large and firaly complex state machine at work. It has 31 possbile states to be in. It has the following inputs: Enum: Current State (so 0 - 30) Enum: source (currently only 2 entries) Boolean: Request Boolean: type Enum: Status (3 states) Enum: Handling (3 states) Boolean: Completed The 31 States are really needed (big business process). Breaking into seperate state machines doesnt seem feasable - each state is distinct. I have written tests for one set of inputs (the most common set), with one test per input (all inputs constant, except for the State input): [Subject("Application Process States")] public class When_state_is_meeting2Requested : AppProcessBase { Establish context = () => { //Setup.... }; Because of = () => process.Load(jas, vac); It Current_node_should_be_meeting2Requested = () => process.CurrentNode.ShouldBeOfType<meetingRequestedNode>(); It Can_move_to_clientDeclined = () => Check(process, process.clientDeclined); It Can_move_to_meeting1Arranged = () => Check(process, process.meeting1Arranged); It Can_move_to_meeting2Arranged = () => Check(process, process.meeting2Arranged); It Can_move_to_Reject = () => Check(process, process.Reject); It Cannot_move_to_any_other_state = () => AllOthersFalse(process); } As no one is entirely sure on what the output should be for each state and set of inputs i have been starting to write tests for it, however on calculation i will need to write 4320 ( 30*2*2*2*3*3*2 ) tests for it. Does anyone have any suggestions on how i should go about testing this?

  • Memory usage in Flash / Flex / AS3

    - by ggambett
    I'm having some trouble with memory management in a flash app. Memory usage grows quite a bit, and I've tracked it down to the way I load assets. I embed several raster images in a class Embedded, like this [Embed(source="/home/gabriel/text_hard.jpg")] public static var ASSET_text_hard_DOT_jpg : Class; I then instance the assets this way var pClass : Class = Embedded[sResource] as Class; return new pClass() as Bitmap; At this point, memory usage goes up, which is perfectly normal. However, nulling all the references to the object doesn't free the memory. Based on this behavior, looks like the flash player is creating an instance of the class the first time I request it, but never ever releases it - not without references, calling System.gc(), doing the double LocalConnection trick, or calling dispose() on the BitmapData objects. Of course, this is very undesirable - memory usage would grow until everything in the SWFs is instanced, regardless of whether I stopped using some asset long ago. Is my analysis correct? Can anything be done to fix this?

  • Problem with twitter API: cannot update status

    - by PainBringer
    I am trying to create Google Chrome extension that will send interesting links to twitter. But, I am unable to connect to the Twitter. The server gets my request, but the response is always the same: "You do not have permission to access /1/statuses/update.json on this server (403 Forbidden)." I am using Wireshark to inspect Http responses. Here is the code of the function i am using: function setStatus(msg) { var status = "status="+msg; var client = new XMLHttpRequest(); client.open("POST","http://api.twitter.com/1/statuses/update.json"); client.setRequestHeader("Authorization", "Basic <user credentials>"); client.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); client.onreadystatechange = function(){ if(client.readyState ==4){ //whatever } } client.send(status); Am I doing something wrong? I am using Basic Auth. I use this tool to do the encoding, and just put the result instead of . Also, can someone give me an example of OAuth?

  • Remove "Flash" between pages while using Internet Explorer modal boxes

    - by AaronS
    I have an internal web application, that is IE specific, and uses a lot of IE specific modal boxes: (window.showModalDialog). I recently received a request to remove the "flash" when navigating between pages of the site. To accomplish this, I just added a meta transition tag to my master page: <meta http-equiv="Page-Enter" content="blendTrans(duration=0.0)" /> This works perfectly except for the modal boxes. When you launch a modal box, and then move it around, the web page behind it keeps a trail of the modal box instead of re-drawing the web page content. This prevents the user from moving the modal box to read anything that was behind it. Is there a way to prevent the "flash" between pages in an IE specific site and have the site still work with modal boxes? Please note, this is a large and complex site, so re-architecting it to not use modal boxes isn't an option. This is an asp.net, c# web application, and all of my users are using IE 7 and IE 8 if it makes any difference. -Edit- To duplicate this, put the following into an html page, and open it in Internet Explorer: <html> <head> <title>Test</title> <meta content="blendTrans(duration=0.0)" http-equiv="Page-Exit"> </head> <body> <script language="javascript"> window.showModalDialog('modal.htm', window); </script> </body> </html>

  • jQuery validation plugin - removing elements

    - by d3020
    I'm using the jQuery validation plugin. On most of my input type... tags I have class='required'. When I submit the page, via JavaScript, the controls on the page that have this class are found. However, there are a handful of checkboxes that I don't need to validate. I've tried removing the class code completely from the input tag, also tried class='cancel', and class='required:false. When doing any of those things though when the form submits it can't find the checkbox control. How do I still keep the ability to do Request.Form and find my checkbox object but at the same time when the form submits don't apply validation to this particular control. Thank you. Edit here. This is what I'm using without the "checked" code and ternary operator. In my input tag I'm calling a function like this... sb.Append(" " + crlf); Inside that function is where I check for the True or False coming back, like this. case "chkFlashedCarton": strResultValue = pst.FlashedCarton.ToString(); if (strResultValue == "True") { strResultValue = " checked"; } break; strResultValue is what is returned back. Does this help to see? Thank you.

  • Reading and writing XML over an SslStream

    - by Mark
    I want to read and write XML data over an SslStream. The data (written and read) consists of objects serialized by an XmlSerializer. I have tried the following; (left some details out for clarity!) TcpClient tcpClient = new TcpClient(server, port); SslStream sslStream = new SslStream(tcpClient.GetStream(), true, new RemoteCertificateValidationCallback(ValidateServerCertificate), null); sslStream.AuthenticateAsClient(server); XmlReader xmlReader = XmlReader.Create(sslStream,readerSettings); XmlWriter xmlWriter = XmlWriter.Create(sslStream,writerSettings); myClass c = new myClass (); XmlSerializer serializer = new XmlSerializer(typeof(myClass)); serializer.Serialize(xmlWriter, c); myClass c2 = (myClass )serializer.Deserialize(xmlReader); First of all, it appears that writing to the stream succeeds. But the XmlSerializer throws an error because of invalid XML. It appears that the first character read from the stream is '00' or a null-character. (I have googled this problem, and see a million people with the same 'problem', but no viable solution.) I can work around this 'issue' by using a StreamReader, read everything into a string and then use that string as input for another stream that the serializer can use. (Very dirty, but it works.) Second problem is, that when I try to use the same SslStream to write a second request, I do not get a response from the Reader. (The server DOES send a valid XML response though!) So the serializer.Serialize(xmlWriter, c3) works, but reading from the stream yields no results. I have tried several different classes that implement Stream. (StreamReader, XmlTextReader, etc.) Anyone has an idea how reading and writing XML data to and from an SslStream is supposed to work? Thanks in advance!

  • Qt - QWebView Problem

    - by user547057
    Hi, I have a PyQt gui script which consists of a QWebView widget. I'm trying to send a GET request, i.e go to a page, fill a form and hit click using the code at the bottom of this question. Since i'm dealing with the documentElement(a QWebElement) of the webview, I need to place all DOM actions in a separate function(which I have named fillForm) and connect the loadFinished() signal into the function. Without connecting the signal, the document will not have loaded and I won't be able to get the elements I want. I'm able to submit the form correctly and get the proper response from the webpage. The problem i'm having is that, the above leads to a sort of infinite loop. This is because the webpage gets reloaded each time a new page is loaded, so the form gets filled each and every single time without stopping. I'd like to know if there's some way of finding out whether the WebView's page has loaded fully, non-asynchronously or maybe pause execution of the script(without freezing the gui) until the whole document has loaded. I'm unable to come up with a satisfactory solution(my idea consisted of keeping a global variable to track clicks) to this problem. I would appreciate it if someone could help me out with a better way to tackle this. Thanks! Here's the code i'm using import sys from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtWebKit import * from PyQt4 import QtCore app = QApplication(sys.argv) web = QWebView() web.load(QUrl("http://mywebsite.com")) def fillForm(): doc = web.page().mainFrame().documentElement() searchform = doc.findFirst("input[type=text]") searchform.setAttribute("value", "hello") button = doc.findFirst("input[type=submit]") button.evaluateJavaScript("click()") QtCore.QObject.connect(web, QtCore.SIGNAL("loadFinished"), fillForm) web.show() sys.exit(app.exec_())

  • Custom Calculations in a Matrix - Reporting Services 2005

    - by bfrancis
    I am writing a report to show gas usage (in gallons) used by each department. The request is to view each month and the gallons used by each department. A column is required to display what each departments target goal is, based on the gallons of gas they have used in a past time frame. Each departments target goal is x percent less than the total gallons used for said time frame. I currently have a matrix in Reporting Services with departments making up rows, months making up columns, and gallons filling the details. The matrix is being filled by dataset1. I have the data grouping as is requested for each month by each department. My problem is calculating the target goal. My thought was to create a second dataset (dataset2) that returns the gallons used based on the time frame requested. I grouped this data by department. I was hoping I could use the department field in each dataset to make sure the appropriate numbers were used. I added a new column which shows up next to the gallons field. As I attempted to build the Expression I found out that I could only grab the gallons used from dataset2 if I was summing the gallons field. This gives me the total gallons used by every department combined. I have tried to find resources with similar examples of what I am trying to accomplish but I cannot seem to come across one. I am trying to keep this as detailed as possible without making it too wordy. I would be more than happy to clarify or explain into further detail what I have written above if it is needed. If anyone has links, comments, or suggestions they would be greatly appreciated. A very simple visual or what I am hoping to accomplish is below. The months and departments would expand based on the data returned. months ------------------------------ departments| gallons/month | target goal

  • Loader.php trying to load Doctrine classes, but we use Propel!

    - by kewpiedoll99
    We are finding cases where we get the following 500 error: File xyz.php does not exist or class "xyz" was not found in the file at () in SF_ROOT_DIR/lib/vendor/Zend/Loader.php line 107 ... where xyz == Memcache (when trying to use symfony cc on the command line) or sfDoctrineAdminGenerator (when using an old-ish AdminGenerator-generated CMS page). We use Propel, but Loader.php is trying to load classes used only for Doctrine. Currently I am using a filthy hack where I request Loader.php to check if the file is either of these two cases, and if so simply return rather than trying to load it. Obviously, this is unacceptable longer term. Has anybody encountered this, and how did you solve it? Edited to add: We have: class ProjectConfiguration extends sfProjectConfiguration { public function setup() { // for compatibility / remove and enable only the plugins you want $this->enableAllPluginsExcept(array('sfDoctrinePlugin')); } } And we have a propel.ini file in our top level config directory. This has only started in the past four weeks or so, and we've had a stable build for over a year now. I'm pretty sure Doctrine is totally disabled.

  • sem-dynamic cdn

    - by dwi kristianto
    i'm developing couple of websites using php (directory script, etc.) and wordpress as cms. i need to improve its performance, by using cdn for static files (css, js, images). the problem is, css and javascript files are generated on the fly. i did that due to yahoo and some expert advice to combine the files into one file. also changing basic color of css files. for the time being, i use couple of small vps but still its not fast enough. i already contact maxcdn and the support guy said that they dont have such kind of services. what i need is: a cdn that will serve the request from user/visitor and there's no file in local disk, the cdn will redirect/fetch it from another domain/server. in vps, it could be done easily using combination of .htaccess and php, but NOT in the cdn. most of cdn only support purely static files. is there any such cdn that will server semi-dynamic files?

  • Authentication using cookie key with asynchronous callback

    - by greg
    I need to write authentication function with asynchronous callback from remote Auth API. Simple authentication with login is working well, but authorization with cookie key, does not work. It should checks if in cookies present key "lp_login", fetch API url like async and execute on_response function. The code almost works, but I see two problems. First, in on_response function I need to setup secure cookie for authorized user on every page. In code user_id returns correct ID, but line: self.set_secure_cookie("user", user_id) does't work. Why it can be? And second problem. During async fetch API url, user's page has loaded before on_response setup cookie with key "user" and the page will has an unauthorized section with link to login or sign on. It will be confusing for users. To solve it, I can stop loading page for user who trying to load first page of site. Is it possible to do and how? Maybe the problem has more correct way to solve it? class BaseHandler(tornado.web.RequestHandler): @tornado.web.asynchronous def get_current_user(self): user_id = self.get_secure_cookie("user") user_cookie = self.get_cookie("lp_login") if user_id: self.set_secure_cookie("user", user_id) return Author.objects.get(id=int(user_id)) elif user_cookie: url = urlparse("http://%s" % self.request.host) domain = url.netloc.split(":")[0] try: username, hashed_password = urllib.unquote(user_cookie).rsplit(',',1) except ValueError: # check against malicious clients return None else: url = "http://%s%s%s/%s/" % (domain, "/api/user/username/", username, hashed_password) http = tornado.httpclient.AsyncHTTPClient() http.fetch(url, callback=self.async_callback(self.on_response)) else: return None def on_response(self, response): answer = tornado.escape.json_decode(response.body) username = answer['username'] if answer["has_valid_credentials"]: author = Author.objects.get(email=answer["email"]) user_id = str(author.id) print user_id # It returns needed id self.set_secure_cookie("user", user_id) # but session can's setup

  • How do I use HttpWebRequest GET method w/ ContentType="application/json"

    - by Stephen Patten
    Hello, This one is real simple, run this Silverlight4 example with the ContentType property commented out and you'll get back a response from from my service in xml. Now uncomment the property and run it and you'll get an ProtocolViolationException, what should happen is the service returns JSON formatted data. HttpWebRequest wreq = (HttpWebRequest)WebRequestCreator.ClientHttp.Create(new Uri("http://stephenpattenconsulting.com/Services/GetFoodDescriptionsLookup(2100)")); //wreq.ContentType = "application/json"; wreq.BeginGetResponse((cb) => { HttpWebRequest rq = cb.AsyncState as HttpWebRequest; HttpWebResponse resp = rq.EndGetResponse(cb) as HttpWebResponse; // Exception StreamReader rdr = new StreamReader(resp.GetResponseStream()); string result = rdr.ReadToEnd(); rdr.Close(); }, wreq); EDIT: While perusing SO, I noticed similar posts, like this one Why am I getting ProtocolViolationException when trying to use HttpWebRequest? and this one How do I use HttpWebRequest with GET method EDIT: The WCF 4 end point is 'adapted' from this link http://geekswithblogs.net/michelotti/archive/2010/08/21/restful-wcf-services-with-no-svc-file-and-no-config.aspx. I can use Fiddler's request builder to to construct the proper requests and changing the content type does yield the correct results.

  • comparing strings from two different sources in javascript

    - by andy-score
    This is a bit of a specific request unfortunately. I have a CMS that allows a user to input text into a tinymce editor for various posts they have made. The editor is loaded via ajax to allow multiple posts to be edited from one page. I want to be able to check if there were edits made to the main text if cancel is clicked. Currently I get the value of the text from the database during the ajax call, json_encode it, then store it in a javascript variable during the callback, to be checked against later. When cancel is clicked the current value of the hidden textarea (used by tinymce to store the data for submission) is grabbed using jquery.val() and checked against the stored value from the previous ajax call like this: if(stored_value!=textarea.val()) { return true } It currently always returns true, even if no changes have been made. The issue seems to be that the textarea.val() uses html entities, whereas the ajax jsoned version doesn't. the response from ajax in firebug looks like this: <p>some text<\/p>\r\n<p>some more text<\/p> the textarea source code looks like this: &lt;p&gt;some text&lt;/p&gt; &lt;p&gt;some more text&lt;/p&gt; these are obviously different, but how can I get them to be treated as the same when evaluated? Is there a function that compares the final output of a string or a way to convert one string to the other using javascript? I tried using html entities in the ajax page, but this returned the string with html entities intact when alerted, I assume because json_encoding it turned them into characters. Any help would be greatly appreciated.

  • C# Byte[] to Url Friendly String

    - by LorenVS
    Hello, I'm working on a quick captcha generator for a simple site I'm putting together, and I'm hoping to pass an encrypted key in the url of the page. I could probably do this as a query string parameter easy enough, but I'm hoping not too (just because nothing else runs off the query string)... My encryption code produces a byte[], which is then transformed using Convert.ToBase64String(byte[]) into a string. This string, however, is still not quite url friendly, as it can contain things like '/' and '='. Does anyone know of a better function in the .NET framework to convert a byte array to a url friendly string? I know all about System.Web.HttpUtility.UrlEncode() and its equivalents, however, they only work properly with query string parameters. If I url encode an '=' inside of the path, my web server brings back a 400 Bad Request error. Anyways, not a critical issue, but hoping someone can give me a nice solution **EDIT: Just to be absolutely sure exactly what I'm doing with the string, I figured I would supply a little more information. The byte[] that results from my encryption algorithm should be fed through some sort of algorithm to make it into a url friendly string. After this, it becomes the content of an XElement, which is then used as the source document for an XSLT transformation, and is used as a part of the href attribute for an anchor. I don't believe the xslt transformation is causing the issues, since what is coming through on the path appears to be an encoded query string parameter, but causes the HTTP 400 I've also tried HttpUtility.UrlPathEncode() on a base64 string, but that doesn't seem to do the trick either (I still end up with '/'s in my url)**

  • How to store a file on a server(web container) through a Java EE web application?

    - by Yatendra Goel
    I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

  • Runtime Exception when using Custom Healthmonitoring event in medium trust

    - by Elementenfresser
    Hi, I'm using custom healthmonitoring events in ASP.NET We recently moved to a new server with default High Trust Permissions. Literature says that healthmonitoring and custom events should work under Medium or higher trust (http://msdn.microsoft.com/en-us/library/bb398933.aspx). Problem is it doesn't. In less than high trust I get a SecurityException saying The application attempted to perform an operation not allowed by the security policy It works in Full trust or when I remove the inheritance of System.Web.Management.WebErrorEvent.

  • Sending jpegs by tcp socket...sometimes incomplete.

    - by Guy
    Vb.net Hi I've been working on a project for months now (vb 2008 express). There is one final problem which I can't solve. I need to send images to a client from a 'server'(listener). The code below works most of the time but sometimes the image is incomplete. I believe this might be something to do with the tcp packet sizes varying, maybe limited by how busy it is out there on the net. I have seen examples of code that splits the image into chunks and sends them out, but I can't get them to work maybe because I'm using a different vb version. The pictures to be sent are small 20k max. Any working code examples would be wonderful. I have been experimenting and failing with this final hurdle for weeks. Thanks in anticipation.

  • Modify post data with a custom MVC extension?

    - by Jaxidian
    So I'm looking into writing some custom MVC extensions and the first one I'm attempting to tackle is a FormattedTextBox to handle things such as currency, dates, and times. I have the rendering of it working perfectly, formatting it, working with strong types and everything all golden. However, the problem I'm now running into is cleaning up the formatted stuff when the page posts the data back. Take for example, a currency format. Let's use USD for these examples. When an object has a property as a decimal, the value would be 79.95. Your edit view would be something like: <%= Html.FormattedTextBox(model => Model.Person.HourlyWage, "{0:C}") %> This is all well and good for the GET request, but upon POST, the value is going to be $79.95, which when you assign to that decimal, gets unhappy very quickly and ends up shoving a 0 in there. So my question is, how do I get code working somewhere to work with that value before the MVC Framework goes and starts shoving it back into my ViewModel? I'd much rather this be done server-side than client-side. Thanks!!

  • ASP.NET Panel FindControl within DataList to change property C#

    - by SDC
    I'm new to this ASP.NET stuff. In my page I have a Datalist with a FooterTemplate. In the footer I have a couple panels that will be visible depending on the QueryString. The problem I am having is trying to find these panels on Page_Load to change the Visible Property. For example this is part of the aspx page: <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> <asp:DataList ID="dlRecords" runat="server"> <FooterTemplate> <asp:Panel ID="pnlArticleHeader" runat="server" Visible="false" > </asp:Panel> </FooterTemplate> </asp:Datalist> </asp:Content> Here is something in the codebehind: protected void Page_Load(object sender, EventArgs e) { location = Request.QueryString["location"]; if (location == "HERE") { Panel pnlAH = *Need to find control here*; pnlAH.Visible=true; } } Like I said I am new at this. Everything I have found doesn't seem to work so I decided to post a specific question. Thanks in advance

  • Browser: Cookie lost on refresh

    - by Nirmal
    I am experiencing a strange behaviour of my application in Chrome browser (No problem with other browsers). When I refresh a page, the cookie is being sent properly, but intermittently the browser doesn't seem to pass the cookie on some refreshes. This is how I set my cookie: $identifier = / some weird string /; $key = md5(uniqid(rand(), true)); $timeout = number_format(time(), 0, '.', '') + 43200; setcookie('fboxauth', $identifier . ":" . $key, $timeout, "/", "fbox.mysite.com", 0); This is what I am using for page headers: header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 header("Expires: Thu, 25 Nov 1982 08:24:00 GMT"); // Date in the past Do you see any issue here that might affect the cookie handling? Thank you for any suggestion. EDIT-01: It seems that the cookie is not being sent with some requests. This happens intermittently and I am seeing this behaviour for ALL the browsers now. Has anyone come across such situation? Is there any situation where a cookie will not be sent with the request? Thanks again, for any guideline.

  • Practiaal rules for Django MiddleWare ordering?

    - by o_O Tync
    The official documentation is a bit messy: 'before' & 'after' are used for ordering MiddleWare in a tuple, but in some places 'before'&'after' refers to request-response phases. Also, 'should be first/last' are mixed and it's not clear which one to use as 'first'. I do understand the difference.. however it seems to complicated for a newbie in Django. Can you suggest some correct ordering for builtin MiddleWare classes (assuming we enable all of them) and — most importantly — explain WHY one goes before/after other ones? here's the list, with the info from docs I managed to find: UpdateCacheMiddleware Before those that modify 'Vary:' SessionMiddleware, GZipMiddleware, LocaleMiddleware GZipMiddleware Before any MW that may change or use the response body After UpdateCacheMiddleware: Modifies 'Vary:' ConditionalGetMiddleware Before CommonMiddleware: uses its 'Etag:' header when USE_ETAGS=True SessionMiddleware After UpdateCacheMiddleware: Modifies 'Vary:' Before TransactionMiddleware: we don't need transactions here LocaleMiddleware, One of the topmost, after SessionMiddleware, CacheMiddleware After UpdateCacheMiddleware: Modifies 'Vary:' After SessionMiddleware: uses session data CommonMiddleware Before any MW that may change the response (it calculates ETags) After GZipMiddleware so it won't calculate an E-Tag on gzipped contents Close to the top: it redirects when APPEND_SLASH or PREPEND_WWW CsrfViewMiddleware AuthenticationMiddleware After SessionMiddleware: uses session storage MessageMiddleware After SessionMiddleware: can use Session-based storage XViewMiddleware TransactionMiddleware After MWs that use DB: SessionMiddleware (configurable to use DB) All *CacheMiddleWare is not affected (as an exception: uses own DB cursor) FetchFromCacheMiddleware After those those that modify 'Vary:' if uses them to pick a value for cache hash-key After AuthenticationMiddleware so it's possible to use CACHE_MIDDLEWARE_ANONYMOUS_ONLY FlatpageFallbackMiddleware Bottom: last resort Uses DB, however, is not a problem for TransactionMiddleware (yes?) RedirectFallbackMiddleware Bottom: last resort Uses DB, however, is not a problem for TransactionMiddleware (yes?) (I will add suggestions to this list to collect all of them in one place)

  • calculating offer period for subscription

    - by TheVillageIdiot
    I'm maintaining a web application which deals with some kind of subscriptions. Users can to renew their subscriptions from 2 months before expiry (not earlier than that). Sometimes user does not renew before expiry and get grace period which is of 3 months. Now he can renew in these 3 months of grace period. Now the problem part. In the previous transactions of renew requests I have to show what was the offer period for that particular request (subscription start and subscription end period if renew was granted). Things are pretty simple if user renews before expiry, but I'm not able to get things straight if there is grace period specially when the subscriptions is expiring in last months of the year. Also there sometimes calculations go haywire when subscription is ending in jan or feb. All this is happening because offer period is not saved with the application anywhere (I don't know why). so if subscription is ending in 20 October 2008 and renew application is submitted in 16 January 2009 (because of grace period) the offer period should be 21 October 2008 to 20 October 2009.
