  • Extending the User model with custom fields in Django

    - by Gaurav
    I am trying to extend the User model so that I can add my own custom fields but I keep getting an error stating: 'NoneType' object has no attribute '_default_manager' whenever I try to use user.get_profile() to add values to the custom field i.e. whenever I use it like so: user = User.objects.create_user(username, email, password) user.first_name = fname user.last_name = lname user.save() uinfo = user.get_profile() uinfo.timezone = "Asia/Pune" uinfo.save() I have already followed the steps given at http://stackoverflow.com/questions/44109/extending-the-user-model-with-custom-fields-in-django/965883#965883 with no luck.

  • Truly declarative language?

    - by gjvdkamp
    Hi all, Does anyone know of a truly declarative language? The behaviour I'm looking for is kind of what Excel does, where I can define variables and formulas, and have the formula's result change when the input changes (without having set the answer again myself) The behaviour I'm looking for is best shown with this pseudo code: X = 10 // define and assign two variables Y = 20; Z = X + Y // declare a formula that uses these two variables X = 50 // change one of the input variables ?Z // asking for Z should now give 70 (50 + 20) I've tried this in a lot of languages like F#, python, matlab etc, but every time i try this they come up with 30 instead of 70. Wich is correct from an imperative point of view, but i'm looking for a more declerative behaviour if you know what i mean. And this is just a very simple calculation. When things get more difficult it should handle stuff like recursion and memoization automagically. The code below would obviously work in C# but it's just so much code for the job, i'm looking for something a bit more to the point without all that 'technical noise' class BlaBla{ public int X {get;set;} // this used to be even worse before 3.0 public int Y {get;set;} public int Z {get{return X + Y;}} } static void main(){ BlaBla bla = new BlaBla(); bla.X = 10; bla.Y = 20; // can't define anything here bla.X = 50; // bit pointless here but I'll do it anyway. Console.Writeline(bla.Z);// 70, hurray! } This just seems like so much code, curly braces and semicolons that add nothing. Is there a language/ application (apart from Exel) that does this? Maybe I'm no doing it right in the mentioned langauges, or I've completely missed an app that does just this. I prototyped a language/ application that does this (along with some other stuff) and am thinking of productizing it. I just can't believe it's not there yet. Don't want to waste my time. Thanks in advance, Gert-Jan

    I have this input file "https://code.google.com/codejam/contest/351101/dashboard/do/A-large-practice.in?cmd=GetInputFile&problem=374101&input_id=1&filename=A-large-practice.in&redownload_last=1&agent=website&csrfmiddlewaretoken=OWMxNTVmMTUyODBiYjhhN2Q2OTM3ZGJiMTNhNDkwMDF8fDEzNzIxNzI1NTE3ODAzMjA%3D" I tried to read this file :-using freopen("filename.txt",r,stdin); and then I wanted the output written to be written to another text file which I can upload in this codejam practice question for the judge. #include<iostream> #include<cstdio> using namespace std; int main() { int t,k=0,a[2000]; freopen("ab.txt","r",stdin); scanf("%d",&t); while(t--) { freopen("cb.txt","w",stdout); int c; scanf("%d",&c); int n; scanf("%d",&n); for(int i=0;i<n;i++) scanf("%d",&a[i]); printf("Case #%d: ",++k); for(int i=0;i<n-1;i++) {for(int j=i+1;j<n;j++) if((a[i]+a[j])==c) {printf("%d %d\n",i+1,j+1); i=n;} } } return 0; } This is my code. Now the problem is the output file cb.txt contains only the last line of the input. I want the the whole of the output to be written to cb.txt,so what should I do.

    I have a form text field that I want to allow only numbers and letters in. (i.e., no #$!, etc...)

  • Replace merge fields with text with OpenXML SDK 2.0

    - by uggwar
    What is the best way to remove all merge fields from a word 2010 document using openxml sdk 2.0, and replace them with a simple text? I have some difficulties to remove them cleanly. Have tried to remove all Run objects that includes a FieldCode with a "MERGEFIELD" defined, and appended a new Run with my text. But I am missing something crucial since the field seems to stay defined for this element.

  • c# - SQL - speed up code to DB

    - by user228058
    I have a page with 26 sections - one for each letter of the alphabet. I'm retrieving a list of manufacturers from the database, and for each one, creating a link - using a different field in the Database. So currently, I leave the connection open, then do a new SELECT by each letter, WHERE the Name LIKE that letter. It's very slow, though. What's a better way to do this? TIA

  • VB - Convert Web Site to Web Application

    - by Dave
    Hi This is my first time doing VB :-) I've inherited a web site, which I've converted into a web application in VS2008. The conversion has worked for everything except a Gallery control. The compile error I'm getting is: Type 'Gallery' is not defined in file: gallery_oct07.aspx.designer.vb Option Strict On Option Explicit On Partial Public Class gallery_oct07 '''<summary> '''Gallery1 control. '''</summary> '''<remarks> '''Auto-generated field. '''To modify move field declaration from designer file to code-behind file. '''</remarks> Protected WithEvents Gallery1 As Global.Gallery End Class with squiggly lines under Global.Gallery. The gallery_oct07.aspx.vb is: Partial Class gallery_oct07 Inherits System.Web.UI.Page End Class Gallery.ascx is: <%@ Control Language="C#" AutoEventWireup="true" Codebehind="Gallery.ascx.cs" Inherits="WebApplication1.Gallery"%> <asp:Repeater runat="server" ID="rptGallery"> <HeaderTemplate> <ul class='<%#CssClass%>'> </HeaderTemplate> <ItemTemplate> <li><a href='<%#ImageFolder + Eval("Name") %>' class="thickbox" rel="gallery"><img src='<%#ImageFolder + "thumb/" + Eval("Name") %>' /></a></li> </ItemTemplate> <FooterTemplate> </ul></FooterTemplate> </asp:Repeater> and the code behind is: using System; using System.IO; namespace WebApplication1 { public partial class Gallery : System.Web.UI.UserControl { public string _ImageFolder; public string ImageFolder { get { return _ImageFolder; } set { _ImageFolder = value; } } private string _cssClass = "gallery"; public string CssClass { get { return _cssClass; } set { _cssClass = value; } } protected void Page_Load(object sender, EventArgs e) { DirectoryInfo dir = new DirectoryInfo(MapPath(ImageFolder)); FileInfo[] images = dir.GetFiles("*.jpg"); rptGallery.DataSource = images; rptGallery.DataBind(); } protected void Page_PreRender(object sender, EventArgs e) { } } } The feels like a namespace issue.. My project namespace is WebApplication1. Cheers!

  • undefined returned for currentView object in Backbone.Marionette

    - by ontk
    I am testing how a layout can listen to its subviews's custom events. I created a jsFiddle here where I have a layout, 2 regions and I instantiated 2 ItemViews and showed them in the layout's regions. The fiddle is in CoffeeScript. <div id="region"></div> <script id="layout-tmpl" type="text/_"> <h3>Heading</h3> <div id="content"></div> <div id="content2"></div> </script> <script id="item-tmpl" type="text/_"> <form> <label>Firstname:</lable> <input type="text" name="firstname" value="<%= firstname %>" /> <input type="button" value="Save" id="save" /> </form> </script> And the CoffeeScript is: SimpleLayout = Backbone.Marionette.Layout.extend template: '#layout-tmpl' regions: main: '#content' other: '#content2' initialize: () -> console.log @ onShow: () -> _.each @.regionManagers, (region, name, something) => console.log region.currentView # @.bindTo region.currentView, "custom:event", @callback callback: () -> alert "HELL YEAH" SimpleItemView = Backbone.Marionette.ItemView.extend template: "#item-tmpl" events: 'click #save': 'save' save: (evt) -> evt.preventDefault() @.trigger "custom:event" region = new Backbone.Marionette.Region el: "#region" layout = new SimpleLayout() region.show layout layout.main.show new SimpleItemView model: (new Backbone.Model firstname: "Olivier") layout.other.show new SimpleItemView model: (new Backbone.Model firstname: "Travis") I want the layout to listen to the ItemViews's custom events. In the onShow, I am looping through the region managers and trying to access the currentView object but it returns undefined. If I attach the same event handlers outside of the SimpleLayout class and after I show the itemviews, then the layout handlers the custom events properly. Thanks for your help.

  • Jquery and Ajax Post issue

    - by Jerry
    Hello guys I am trying to add a click event on the element that is return from the server via ajax. Apparently, I have to attached my js file inside my return response instead of my main script. Is this the best practice? Do I have to create the separated js file to add event on the return text?? Example: My Jquery - selectWeek.js $(document).ready(function(){ //handle ajax.. var url="sendSchedule.php"; $.post( url, {week:input}, function(responseText){ $("#ajax").html(responseText); }, "html" ); // click on #add button $("#add").click(function(){ //do something return false; }); }); My main page <script type="text/javascript" src="JS/selectWeek.js"></script> </HEAD> <BODY> //the code that trigger ajax is omitted <div id=ajax> //the response text will be inserted here </div> </BODY> </HTML> response from the server // display html (omit) // Do I have to attach the same js file to let #add listen the event? <script type="text/javascript" src="JS/selectWeek.js"></script> <form> <input type='button' id='add' value='add'/> </form> I am not sure if i make my question clear. I want to know if I need to add events on the return text. Do I have to add js file link on the return text or there is a way to do it on the main page. Thanks for any reply.

  • PHP code to convert a MySQL query to CSV

    What is the most efficient way to convert a MySQL query to CSV in PHP please? It would be best to avoid temp files as this reduces portability (dir paths and setting file-system permissions required). The CSV should also include one top line of field names. Cheers.

  • Javascript/PHP popup page problem

    I have a program in PHP that allows user to pop in a message, for confirmation from user. As seen below is the link i used. From inbox.php: echo "<a href='inbox.php' onclick=\"popup('acknowledge.php?id=$id')\"><font size=1px color=maroon>acknowledge</font></a></td>"; From acknowledge.php: if ($_POST['no']) { header("location: inbox.php"); } ?> <body bgcolor=skyblue> <center><form name=form1 method=post> <b><u> Acknowledge Message </u></b><br><br> Are you sure yout want to acknowledge this message?<br><br> <input type=button name=yes value="Yes"> &nbsp; <input type=submit name="no" value="No" onSubmit="window.close()"> </form> </center> </body> The problem is, everytime i click "no", to go back from previous page. It sets the page size the same as the popup page. It becomes smaller too. What's the problem? Answers are very much appreciated.

  • How can I get contentWindow for an Object element in IE7

    - by Scott Leis
    I have a HTML object element like this: <object title="Search results as XML" standby="Loading XML document..." type="text/xml" data="/__CA25761100195585.nsf/WebPrintListingXML?OpenAgent&date1=01/06/2009" width="100%" height="100%" border="0" name="resultIFrame" id="resultIFrame" Error: could not embed search results. </object I also have this javascript function (alert() calls added for debugging): function getFrameByName(fParent,fName) { var fArray=fParent.frames; if (!fName) return; if (fArray) { if (fArray.length) { for (var i=0; i<fArray.length; i++) { alert('loop '+i); if (fArray[i]) { if (fArray[i].name==fName) return fArray[i]; } } } } var tmp=document.getElementsByName(fName); if (tmp[0]) { alert('returning '+tmp[0]); if (!(tmp[0].contentWindow)) alert('contentWindow is null'); return tmp[0].contentWindow; } } And finally, this button is meant to print the content of the Object element: <input type="button" value="Print" name="printBtn" onclick="getFrameByName(window,'resultIFrame').print();" The button works perfectly in Firefox. Opera is good enough, though it prints the main document instead of just the object. IE7 gives the following error details: Line: 57 Char: 1 Error: 'undefined' is null or not an object Line 57 is where the button's "input" tag starts in the HTML source. Thanks to the alert('contentWindow is null') call in the JS function, I know that the object I'm getting in IE has no contentWindow property. I have tried changing the object tag to an iframe tag. This changes the JS behaviour, but causes other issues such as the height attribute being ignored and the content not displaying. Sticking with an object tag, how can I get this Object's window in IE7?
