  • Problem with validating ModelForm

    - by user561640
    I use ModelForm to create my form. All works fine except 1 thing - validating the unique field. Code: class Article(models.Model): ... title = models.CharField(max_length=255, unique=True, error_messages={'max_length' : 'max translation', 'unique' : 'unique translation', 'required' : 'req translation',}) ... class ArticleForm(ModelForm): ... title = forms.CharField(max_length=255, min_length=3, error_messages={'required' : 'req translation', 'min_length' : 'min translation', 'max_length' : 'max translation', 'unique' : 'unique translation',}) But when I save my form with non-unique title I don't get my custom translated error but I get default error. How to fix it, that my unique field error is displayed?

  • Creating files on a time (hourly) basis

    - by Yaniv
    Hi there, I experimenting with twitter streaming API, I use Phirehose to connect to twitter and fetch the data but having problems storing it in files for further processing. Basically what I want to do is to create a file named date("YmdH")."."txt" for every hour of connection. Here is how my code looks like right now (not handling the hourly change of files) public function enqueueStatus($status) $data = json_decode($status,true); if(isset($data['text'])/*more conditions here*/) { $fp = fopen("/tmp/$time.txt"); fwirte ($status,$fp); fclose($fp); } Help is as always much appreciated :)

  • ask. help me to compare two array of integers and the order does not matter.

    - by stdnoit
    [Example] <1 2 3 4 = <3 1 2 4 <1 2 3 4 != <3 4 1 1 and ummm it is in java. cant use hashmap table or anything just pure without library. I know there are two ways. 1. sort them and compare the array index by index 2. use two for loops and compare the outer index with the inner index. ( i have been trying with this but still not working) for(int i = 0; i < n; i++) { for(int j = 0; j < n; j++) { if(a[i] != a[j] && j == n) return false; } } return true; anything wrong with the code ? thanks

  • Django Find Out if User is Authenticated in Custom Tag

    - by greggory.hz
    I'm trying to create a custom tag. Inside this custom tag, I want to be able to have some logic that checks if the user is logged in, and then have the tag rendered accordingly. This is what I have: def user_actions(context): request = template.Variable('request').resolve(context) return { 'auth': request['user'].is_athenticated() } register.inclusion_tag('layout_elements/user_actions.html', takes_context=True)(user_actions) When I run this, I get this error: Caught VariableDoesNotExist while rendering: Failed lookup for key [request] in u'[{}]' The view that renders this ends like this: return render_to_response('start/home.html', {}, context_instance=RequestContext(request)) Why doesn't the tag get a RequestContext object instead of the Context object? How can I get the tag to receive the RequestContext instead of the Context? EDIT: Whether or not it's possible to get a RequestContext inside a custom tag, I'd still be interested to know the "correct" or best way to determine a user's authentication state from within the custom tag. If that's not possible, then perhaps that kind of logic belongs elsewhere? Where?

  • How to user unloadStyleDeclarations?

    - by user300675
    I have a flex4 applciation (mx+spark). When I use: FlexGlobals.topLevelApplication.styleManager.loadStyleDeclarations(skinName, true); This works fine: new style is applied. The trouble is when I apply a new style, it mixes both: this happens because I need to Unload style first. I try to unload it with: FlexGlobals.topLevelApplication.styleManager.unloadStyleDeclarations("style/normal.swf",false); And I always got an error: ReferenceError: Error #1069: La property 0 cannot be found on Number and there is no default value. at normal/unloadOverrides()[null/normal-generated.as:721] at normal/unload()[null/normal-generated.as:676] Any idea on how to load/unload swf css in Flex4?

  • MVC - thin controller idea - Codeigniter/Zend

    - by user505988
    Hi, Could some one possibly clarify this for me. In the MVC paradigm, the idea is to keep the controller as thin as possible, it is also true that the model is the bit that communicates with data sources such as the database, XML-RPC etc and this is where the business logic should go. Is the POST and GET data a 'data source' and should that kind of data be handled by the model or should it be by the controller. I would normally call a method in the model and pass it the post data, the data would be quality checked by the controller and the model method would simply do the insertion or whatever. Should it be though that controller just calls the model method if a post has occured and it is responsible for sanity check, data checks etc.

  • Thread Code...anything wrong with this, must use java 1.4

    - by bmw0128
    I have a servlet automatically firing up when the app server starts, and in its init(), I'm making another thread: init(){ new FooThread() } in FooThread(), i want to periodically check the status of a DB value, then depending on the value, make a web service call. When these two tasks complete, I want the thread to sleep to wait a certain period then repeat. This cycle would just continue forever. FooThread: public class FooThread implements Runnable{ Thread t; FooThread(){ t = new Thread(this, "BBSThread"); logger.info("*** about to start " + t.getName()); t.start(); logger.info("*** started: " + t); } public void run() { try{ while(true){ //do the db check, then conditionally do the web services call logger.info("*** calling sleep() ***"); Thread.sleep(50000); logger.info("*** now awake ***"); } } catch (InterruptedException e) { System.out.println("*** FooThread interrupted"); } } }

  • Java Instance of: Supertypes and Subtypes seem to be equal? How to test exactly for Type?

    - by jens
    I need to test, if an instance is exactly of a given type. But it seems that instanceof returns true also if the subtype is tested for the supertype (case 3). I never knew this before and I am quite surprised. Am I doing something wrong here? How do I exactly test for a given type? //.. class DataSourceEmailAttachment extends EmailAttachment //... EmailAttachment emailAttachment = new EmailAttachment(); DataSourceEmailAttachment emailAttachmentDS = new DataSourceEmailAttachment(); if (emailAttachment instanceof EmailAttachment){ System.out.println(" 1"); } if (emailAttachment instanceof DataSourceEmailAttachment){ System.out.println(" 2"); } if (emailAttachmentDS instanceof EmailAttachment){ System.out.println(" 3 "); } if (emailAttachmentDS instanceof DataSourceEmailAttachment){ System.out.println(" 4"); } RESULT: 1 3 4 I want to avoid case 3, I only want "exact matches" (case 1 and 4) how do I test for them?

  • What's the best way to debug AJAX to PHP calls?

    - by Jascha
    I'm having a miserable time debugging one small function on my new project. Essentially I'm having a user log out via an AJAX call to my log out script on my server called "userfFunctions.php" I'm using AJAX so that I don't have the headache of writing more regex to match my mod_rewrites. Anyway, every so often, it seems as though my Post data just flat out dies and since the PHP is running behind the scenes, I feel like I have no way of finding out where the data flow is being disrupted. BTW This function works 19 hrs of the day. Here is the javascript function: function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/User_Validator', //<-- redirects to userFunctions.php data: data, success: function(data) { alert(data); // <-- a response is triggered but with no response data! } }); } the php side: if(isset($_POST['log_out'])){ echo 'alert this!'; } here is my awesome response:

  • When (and why) is {} undefined in a JavaScript console?

    - by JS_Riddler
    In the console of both FF and Chrome, {} is considered undefined until explicitly evaluated: {}; // undefined ({}); // ? Object Actually, it's a bit less defined than undefined -- it's apparently bad syntax: {} === undefined; // SyntaxError: Unexpected token === {}.constructor; // SyntaxError: Unexpected token . But not if it's on the other side, in which case it's fine: "[object Object]" == {}.toString(); // true Or if it's not the first expression: undefined + undefined; // NaN {} + undefined; // NaN undefined + {}; // "undefined[object Object]" What gives?

  • DirectX equivalent of glBlendFunc(............)

    - by Jimmy Bouker
    I created a particle System in OpenGl that's working great. When I want to get a burning effect of a fire or a beam or something(Where the system kind of "glows" and fuses all the colors together) I use this method call with OpenGL. glBlendFunc(GL_SRC_ALPHA,GL_SRC_ALPHA) glBlendFunc(GL_DST_ALPHA,GL_ONE) I'm now trying to do the same thing using Direct3D Here is what I have tried: graphicsDevice->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE); graphicsDevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCALPHA); graphicsDevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_ONE); but this has absolutely no effect at all on the look of my game! Anyone have a clue what could be the problem?

  • Problem using GDI+ with multiple threads (VB.NET)

    - by Joe B
    I think it would be best if I just copy and pasted the code (it's very trivial). Private Sub Main() Handles MyBase.Shown timer.Interval = 10 timer.Enabled = True End Sub Private Sub Form1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint e.Graphics.DrawImage(image, 0, 0) End Sub Private Sub tick() Handles timer.Elapsed Using g = Graphics.FromImage(image) g.Clear(Color.Transparent) g.DrawLine(Pens.Red, 0 + i, 0 + i, Me.Width - i, Me.Height - i) End Using Me.Invalidate() End Sub An exception, "The object is currently in use elsewhere", is raised during the tick event. Could someone tell me why this happens and how to solve it? Thanks.

  • WCF: What happens if a channel is established but no method is called?

    - by mafutrct
    In my specific case: A WCF connection is established, but the only method with "IsInitiating=true" (the login method) is never called. What happens? In case the connection is closed due to inactivity after some time: Which setting configures this timeout? Is there still a way for a client to keep the connection alive? Reason for this question: I'm considering the above case as a possible security hole. Imagine many clients connecting to a server without logging in thus preventing other clients from connecting due to bandwidth problems or port shortage or lack of processing power or ... Am I dreaming, or is this an actual issue?

  • Best way to validate currency input?

    - by Abe Miessler
    I have created the TextBox and CompareValidator below which I thought would allow input in the following forms: 5 5.00 $5.00 Unfortunately it's not allowing the version with the dollar sign in it. What is the point of doing a type check against currency if you don't allow the dollar sign? Is there a way to allow this symbol? <asp:TextBox ID="tb_CostShare" runat="server" Text='<%# Eval("CostShare", "{0:$0.00}")%>' CausesValidation="true" /> <asp:CompareValidator ID="vld_CostShare" runat="server" ControlToValidate="tb_CostShare" Operator="DataTypeCheck" Type="Currency" ValidationGroup="vld" ErrorMessage="You must enter a dollar amount for 'Cost Share'." />

  • jQuery dialog box not opening 2nd time

    - by Steven
    I found this thread which basically has the same issue I have. But their solution is not working for me. The dialog appears the first time I click the submit button, but not the 2nd time. I'm opening the dialog box after a form submission. UPDATE I finally got it working. Here is the correct code: if (jQuery('#registrationforms').length > 0) { //instantiate the dialog jQuery("#dialog").dialog({ modal:true, autoOpen:false }); //Some more code here to call processRegistration function. } function processRegistration(instanceID, formData) { jQuery.post("mypath/jquery_bll.php", { instance: 'processRegistration', formData : formData, instanceID : instanceID }, function(feedback) { jQuery('#dialog').text(feedback.message); jQuery('#dialog').parent().addClass(feedback.type); jQuery('#dialog').dialog('open'); },"json"); } Since I'm dynamically applying css class, I have to make sure to add it to the outer DIV which $.dialog creates to wrap my 'dialog' DIV.

  • Entity Framework: a proxy collection for displaying a subset of data

    - by Jefim
    Imagine I have an entity called Product and a repository for it: public class Product { public int Id { get; set; } public bool IsHidden { get; set; } } public class ProductRepository { public ObservableCollection<Product> AllProducts { get; set; } public ObservableCollection<Product> HiddenProducts { get; set; } } All products contains every single Product in the database, while HiddenProducts must only contain those, whose IsHidden == true. I wrote the type as ObservableCollection<Product>, but it does not have to be that. The goal is to have HiddenProducts collection be like a proxy to AllProducts with filtering capabilities and for it to refresh every time when IsHidden attribute of a Product is changed. Is there a normal way to do this? Or maybe my logic is wrong and this could be done is a better way?

  • Killing a subprocess including its children from python

    - by user316664
    Hi, I'm using the subprocess module on python 2.5 to spawn a java program (the selenium server, to be precise) as follows: import os import subprocess display = 0 log_file_path = "/tmp/selenium_log.txt" selenium_port = 4455 selenium_folder_path = "/wherever/selenium/lies" env = os.environ env["DISPLAY"] = ":%d.0" % display command = ["java", "-server", "-jar", 'selenium-server.jar', "-port %d" % selenium_port] log = open(log_file_path, 'a') comm = ' '.join(command) selenium_server_process = subprocess.Popen(comm, cwd=selenium_folder_path, stdout=log, stderr=log, env=env, shell=True) This process is supposed to get killed once the automated tests are finished. I'm using os.kill to do this: os.killpg(selenium_server_process.pid, signal.SIGTERM) selenium_server_process.wait() This does not work. The reason is that the shell subprocess spawns another processfor the java program, and the pid of that process is unknown to my python code. I've tried killing the process group with os.killpg, but that kills also the python process which runs this code in the first place. Setting shell to false, thus avoiding the java program to run inside a shell environment, is also out of the question, due to other reasons. Does anyone have an idea how I can kill the shell and any other processes generated by it? Cheers, Ulas
