• jQuery ui datepicker positioning problem when scrolling down webpage

  - by Remnant

  I have a webpage that uses multiple instances of the jQuery ui datepicker. My webpage will display ~80 records which extends beyond a single screenshot. <% foreach (var record in Model) { %> <div class="recordname"><%=record.name%></div> <%=Html.TextBox("DateTimePicker", null, new { @class = "date-pick" } )%> // <-- additional html here --> <% } %> I have set the defaults of my datepicker as follows: $(".date-pick").each(function() { $(this).datepicker({ dateFormat: 'dd M yy', showOn: 'button', buttonImage: '/Images/datepickericon.png', buttonImageOnly: true }); }); When the page first loads, if I click any datepicker icon that is visible on screen (i.e. without scrolling) then the datepicker appears as expected. However, if I scroll down the page and then click a datepicker icon, the datepicker does not appear in the screen window but is instead rendered right back near the top of the screen. Any ideas how to solve this? I am using: IE7 asp.net mvc jquery.ui.datepicker.js (UI/API/1.8/Datepicker)

• Django Form Preview

  - by Mark Kecko

  I'm trying to use django's FormPreview and I can't get it to work properly. Here's my code: forms.py class MyForm(forms.ModelForm): status = forms.TypedChoiceField( coerce=int, choices=LIST_STATUS, label="type", widget=forms.RadioSelect ) description = forms.CharField(widget = forms.Textarea) stage = forms.CharField() def __init__(self, useradd=None, *args, **kwargs): super(MyForm, self).__init__(*args, **kwargs) self.fields['firm'].label = "Firm" class Meta: model = MyModel fields = ['status', 'description', 'stage'] class MyFormPreview(FormPreview): form_template = 'templates/post.html' preview_template = 'templates/review.html' def process_preview(self, request, cleaned_data): print "processed" def done(self, request, cleaned_data): print "done" # Do something with the cleaned_data, then redirect # to a "success" page. return HttpResponseRedirect('/') urls.py (r'^post/$', MyFormPreview(MyForm)), post.html <form id = "post_ad" action = "" method = "POST" enctype="multipart/form-data"> <table> {{form.as_table}} </table> <input type="submit" name="save" value="Post" /> </form> When I go to /post/ I get the correct form and I fill it out. When I submit the form it goes right back to /post/ but but there are no errors (I've tried displaying {{errors}}) and the form is empty. None of my print statements execute. I'm not sure what I'm missing. Can anyone help me out? I can't find any documentation besides what's on the django site. Also, what's the "preview" variable called that I should use in my preview.html template? {{preview}} or do I just do {{form}} again? -- Answered below. I tried adding 'django.contrib.formtools' to my installed_apps in settings and I tried using the code from the default form templates from django.contrib as suggested below. Still, when I submit the form I go right back to the post template, none of my print statements execute :(

• is this valid json array using php

  - by Rich

  Hello, I need to convert some code done by someone else, to work in my mvc model It is using some functions like EOD that I don't understand. Does that still work in a class? Primarely, my question focusus on the json output. The old code does not use the php json_encode function, but outputs it directly like this ?> { "username": "<?php echo $_SESSION['username'];?>", "items": [ <?php echo $items;?> ] } <?php I would do it like this, but I need to be sure it's right for the items part header('Content-type: application/json'); $output = array("username"=> isset( $_SESSION['username'] ) ? $_SESSION['username'] : "?", "items"=>$items ); $this->content = json_encode($output); This is some background on how the $items is made. An item is stored like this: $_SESSION['chatHistory'][$_POST['to']] .= <<<EOD { "s": "1", "f": "{$to}", "m": "{$messagesan}" }, EOD; and it is put in the $items variable like this $items = ''; if ( !empty($_SESSION['openChatBoxes'] ) ) { foreach ( $_SESSION['openChatBoxes'] as $chatbox => $void ) { $items .= $this->chatBoxSession($chatbox); } } //The chatBoxSession() function takes an item from the $_SESSION['chatHistory'] array and returns it. I hope this was somewhat clear enough? The php manual warns that in some cases you don't get an array output, instead you get an object. So, with the EOD syntax, I am not really sure. It could save me some time if I know some things are doing what they supposed too, and giving the right output. thanks, Richard

• nhibernate many to many deletes

  - by asi farran

  I have 2 classes that have a many to many relationship. What i'd like to happen is that whenever i delete one side ONLY the association records will be deleted with no concern which side i delete. simplified model: classes: class Qualification { IList<ProfessionalListing> ProfessionalListings } class ProfessionalListing { IList<Qualification> Qualifications void AddQualification(Qualification qualification) { Qualifications.Add(qualification); qualification.ProfessionalListings.Add(this); } } fluent automapping with overrides: void Override(AutoMapping<Qualification> mapping) { mapping.HasManyToMany(x => x.ProfessionalListings).Inverse(); } void Override(AutoMapping<ProfessionalListing> mapping) { mapping.HasManyToMany(x => x.Qualifications).Not.LazyLoad(); } I'm trying various combinations of cascade and inverse settings but can never get there. If i have no cascades and no inverse i get duplicated entities in my collections. Setting inverse on one side makes the duplication go away but when i try to delete a qualification i get a 'deleted object would be re-saved by cascade'. How do i do this? Should i be responsible for clearing the associations of each object i delete?

• Hibernate bit array to entity mapping

  - by teabot

  I am trying to map a normalized Java model to a legacy database schema using Hibernate 3.5. One particular table encodes a foreign keys in a one-to-many relationship as a bit array column. Consider tables 'person' and 'clubs' that describes people's affiliations to clubs: person .----.------. club: .----.---------.---------------------------. | id | name | | id | name | members | binary(members) | |----+------| |----+---------|---------+-----------------| | 1 | Bob | | 10 | Cricket | 0 | 000 | | 2 | Joe | | 11 | Tennis | 5 | 101 | | 3 | Sue | | 12 | Cooking | 7 | 111 | '----'------' | 13 | Golf | 3 | 100 | '----'---------'---------'-----------------' So hopefully it is clear that person.id is used as the bit index in the bit array club.members. In this example the members column tells us that: no one is a member of Cricket, Bob/Sue - Tennis, Bob/Sue/Joe - Cooking and Sue - Golf. In my Java domain I'd like to declare this with entities like so: class Person { private int id; private String name; ... } class Club { private Set<Person> members; private int id; private String name; ... } I am assuming that I must use a UserType implementation but have been unable to find any examples where the items described by the user type are references to entities - not literal field values - or composites thereof. Additionally I am aware that I'll have to consider how the person entities are fetched when a club instance is loaded. Can anyone tell me how I can tame this legacy schema with Hibernate?

• Flexible Decorator Pattern?

  - by Omar Kooheji

  I was looking for a pattern to model something I'm thinking of doing in a personal project and I was wondering if a modified version of the decorator patter would work. Basicly I'm thinking of creating a game where the characters attributes are modified by what items they have equiped. The way that the decorator stacks it's modifications is perfect for this, however I've never seen a decorator that allows you to drop intermediate decorators, which is what would happen when items are unequiped. Does anyone have experience using the decorator pattern in this way? Or am I barking up the wrong tree? Clarification To explain "Intermediate decorators" if for example my base class is coffe which is decorated with milk which is decorated with sugar (using the example in Head first design patterns) milk would be an intermediate decorator as it decorates the base coffee, and is decorated by the sugar. Yet More Clarification :) The idea is that items change stats, I'd agree that I am shoehorning the decorator into this. I'll look into the state bag. essentially I want a single point of call for the statistics and for them to go up/down when items are equiped/unequiped. I could just apply the modifiers to the characters stats on equiping and roll them back when unequiping. Or whenever a stat is asked for iterate through all the items and calculate the stat. I'm just looking for feedback here, I'm aware that I might be using a chainsaw where scissors would be more appropriate...

• MVC view engine that can render classic ASP?

  - by David Lively

  I'm about to start integrating ASP.NET MVC into an existing 200k+ line classic ASP application. Rewriting the existing code (which runs an entire business, not just the public-facing website) is not an option. The existing ASP 3.0 pages are quite nicely structured (given what was available when this model was put into place nearly 15 years ago), like so: <!--#include virtual="/_lib/user.asp"--> <!--#include virtual="/_lib/db.asp"--> <!--#include virtual="/_lib/stats.asp"--> <!-- #include virtual="/_template/topbar.asp"--> <!-- #include virtual="/_template/lftbar.asp"--> <h1>page name</h1> <p>some content goes here</p> <p>some content goes here</p> <p>.....</p> <h2>Today's Top Forum Posts</h2> <%=forum_top_posts(1)%> <!--#include virtual="/_template/footer.asp"--> ... or somesuch. Some pages will include function and sub definitions, but for the most part these exist in include files. I'm wondering how difficult it would be to write an MVC view engine that could render classic ASP, preferably using the existing ASP.DLL. In that case, I could replace <!--#include virtual="/_lib/user.asp"--> with <%= Html.RenderPartial("lib/user"); %> as I gradually move existing pages from ASP to ASP.NET. Since the existing formatting and library includes are used very extensively, they must be maintained. I'd like to avoid having to maintain two separate versions. I know the ideal way to go about this would be to simply start a new app and say to hell with the ASP code, however, that simply ain't gonna happen. Ideas?

• In Ruby, how to implement global behaviour?

  - by Gordon McAllister

  Hi all, I want to implement the concept of a Workspace. This is a global concept - all other code will interact with one instance of this Workspace. The Workspace will be responsible for maintaining the current system state (i.e. interacting with the system model, persisting the system state etc) So what's the best design strategy for my Workspace, bearing in mind this will have to be testable (using RSpec now, but happy to look at alternatives). Having read thru some open source projects out there and I've seen 3 strategies. None of which I can identify as "the best practice". They are: Include the singleton class. But how testable is this? Will the global state of Workspace change between tests? Implemented all behaviour as class methods. Again how do you test this? Implemented all behaviour as module methods. Not sure about this one at all! Which is best? Or is there another way? Thanks, Gordon

• How to render a DateTime in a specific format in ASP.NET MVC 3?

  - by Slauma

  If I have in my model class a property of type DateTime how can I render it in a specific format - for example in the format which ToLongDateString() returns? I have tried this... @Html.DisplayFor(modelItem => item.MyDateTime.ToLongDateString()) ...which throws an exception because the expression must point to a property or field. And this... @{var val = item.MyDateTime.ToLongDateString(); Html.DisplayFor(modelItem => val); } ...which doesn't throw an exception, but the rendered output is empty (although val contains the expected value, as I could see in the debugger). Thanks for tips in advance! Edit ToLongDateString is only an example. What I actually want to use instead of ToLongDateString is a custom extension method of DateTime and DateTime?: public static string FormatDateTimeHideMidNight(this DateTime dateTime) { if (dateTime.TimeOfDay == TimeSpan.Zero) return dateTime.ToString("d"); else return dateTime.ToString("g"); } public static string FormatDateTimeHideMidNight(this DateTime? dateTime) { if (dateTime.HasValue) return dateTime.Value.FormatDateTimeHideMidNight(); else return ""; } So, I think I cannot use the DisplayFormat attribute and DataFormatString parameter on the ViewModel properties.

• Where to find algorithms for standard math functions?

  - by dsimcha

  I'm looking to submit a patch to the D programming language standard library that will allow much of std.math to be evaluated at compile time using the compile-time function evaluation facilities of the language. Compile-time function evaluation has several limitations, the most important ones being: You can't use assembly language. You can't call C code or code for which the source is otherwise unavailable. Several std.math functions violate these and compile-time versions need to be written. Where can I get information on good algorithms for computing things such as logarithms, exponents, powers, and trig functions? I prefer just high level descriptions of algorithms to actual code, for two reasons: To avoid legal ambiguity and the need to make my code look "different enough" from the source to make sure I own the copyright. I want simple, portable algorithms. I don't care about micro-optimization as long as they're at least asymptotically efficient. Edit: D's compile time function evaluation model allows floating point results computed at compile time to differ from those computed at runtime anyhow, so I don't care if my compile-time algorithms don't give exactly the same result as the runtime version as long as they aren't less accurate to a practically significant extent.

• How can I stop an auto-generated Linq to SQL class from loading ALL data?

  - by Gary McGill

  I have an ASP.NET MVC project, much like the NerdDinner tutorial example. (I'm using MVC 2, but followed the NerdDinner tutorial in order to create it). As per the instructions in part 3 of the tutorial, I've created a Linq-to-SQL model of my database by creating a "Linq to SQL Classes" (.dbml) surface, and dropping my database tables onto it. The designer has automatically added relationships between the generated classes based on my database tables. Let's say that my classes are as per the NerdDinner example, so I have Dinner and RSVP tables, where each Dinner record is associated with many RSVP records - hence in the generated classes, the Dinner object has a RSVPs property which is a list of RSVP objects. My problem is this: it appears (and I'd be gladly proved wrong on this) that as soon as I access a Dinner object, it's loading all of the corresponding RSVP objects, even if I don't use the RSVPs member. First question: is this really the default behavior for the generated classes? In my particular situation, the object graph contains many more tables (which have an order of magnitude more records), and so this is disastrous behaviour - I'd be loading tons of data when all I want to do is show the details of a single parent record. Second question: are there any properties exposed through the designer UI that would let me modify this behavior? (I can't find any). Third question: I've seen a description of how to control the loading of related records in a DataContext by using a DataShape object associated with the DataContext. Is that what I'm meant to do, and if so are there any tutorials like the NerdDinner one that would show not only how to do it, but also suggest a 'pattern' for normal use?

• Set initial view with SkpWriter in Google Sketchup C++ SDK

  - by Peter Olsson

  How do you set the initial view for the model in an SKP file created with the SkpWriter in Google Sketchup C++ SDK? There has been an example in an older version of the SDK. Part of the source is posted here. I'm trying to use: m_pDoc->GetModel()->SetCamera(cameraDefn); The problem is that I'm not able to create a valid atlast::sketchup::CCameraDefinition. Non of the examples in the above post works: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); and: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); In the end I want the initial view to be the view you get from pressing the icon for Zoom extents followed by the Iso icon (the other way around is also ok). Right now I would settle for creating a valid atlast::sketchup::CCameraDefinition. Any better way to achieve this in the SKP-file?

• How do I Unit Test Actions without Mocking that use UpdateModel?

  - by Hellfire

  I have been working my way through Scott Guthrie's excellent post on ASP.NET MVC Beta 1. In it he shows the improvements made to the UpdateModel method and how they improve unit testing. I have recreated a similar project however anytime I run a UnitTest that contains a call to UpdateModel I receive an ArgumentNullException naming the controllerContext parameter. Here's the relevant bits, starting with my model: public class Country { public Int32 ID { get; set; } public String Name { get; set; } public String Iso3166 { get; set; } } The controller action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Int32 id, FormCollection form) { using ( ModelBindingDataContext db = new ModelBindingDataContext() ) { Country country = db.Countries.Where(c => c.CountryID == id).SingleOrDefault(); try { UpdateModel(country, form); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(country); } } } And finally my unit test that's failing: [TestMethod] public void Edit() { CountryController controller = new CountryController(); FormCollection form = new FormCollection(); form.Add("Name", "Canada"); form.Add("Iso3166", "CA"); var result = controller.Edit(2 /*Canada*/, form) as RedirectToRouteResult; Assert.IsNotNull(result, "Expected to be redirected on successful POST."); Assert.AreEqual("Show", result.RouteName, "Expected to redirect to the View action."); } ArgumentNullException is thrown by the call to UpdateModel with the message "Value cannot be null. Parameter name: controllerContext". I'm assuming that somewhere the UpdateModel requires the System.Web.Mvc.ControllerContext which isn't present during execution of the test. I'm also assuming that I'm doing something wrong somewhere and just need to pointed in the right direction. Help Please!

• How can I 'transpose' my data using SQL and remove duplicates at the same time?

  - by Remnant

  I have the following data structure in my database: LastName FirstName CourseName John Day Pricing John Day Marketing John Day Finance Lisa Smith Marketing Lisa Smith Finance etc... The data shows employess within a business and which courses they have shown a preference to attend. The number of courses per employee will vary (i.e. as above, John has 3 courses and Lisa 2). I need to take this data from the database and pass it to a webpage view (asp.net mvc). I would like the data that comes out of my database to match the view as much as possible and want to transform the data using SQl so that it looks like the following: LastName FirstName Course1 Course2 Course3 John Day Pricing Marketing Finance Lisa Smith Marketing Finance Any thoughts on how this may be achieved? Note: one of the reasons I am trying this approach is that the original data structure does not easily lend itself to be iterated over using the typical mvc syntax: <% foreach (var item in Model.courseData) { %> Because of the duplication of names in the orignal data I would end up with lots of conditionals in my View which I would like to avoid. I have tried transforming the data using c# in my ViewModel but have found it tough going and feel that I could lighten the workload by leveraging SQL before I return the data. Thanks.

• Update one-to-many EntityKey using Foreign Key

  - by User.Anonymous

  To use by the easiest way Entity Framework, I use partial class to add Foreign Key on most important Entities Model. For example, I have an Entity "CONTACT" which have "TITLE", "FUNCTION" and others. When I update a CONTACT, with this code, Foreign Key are automatically updated : public int? TitId { get { if (this.TITLE_TIT != null) return TITLE_TIT.TIT_ID; return new Nullable<int>(); } set { this.TITLE_TITReference.EntityKey = new System.Data.EntityKey("Entities.TITLE_TIT", "TIT_ID", value); } } But I have a join with ACTIVITY, that can have many CONTACT, and I don't know how to update EntityKey on setters. public IEnumerable<EntityKeyMember> ActId { get { List<EntityKeyMember> lst = new List<EntityKeyMember>(); if (this.ACT_CON2 != null) { foreach (ACT_CON2 id in this.ACT_CON2.ToList()) { EntityKeyMember key = new EntityKeyMember(id.CON_ID.ToString(),id.ACT_ID); lst.Add(key); } } return lst; } set { this.ACT_CON2.EntityKey = new System.Data.EntityKey("Entities.ACT_CON2", value); } } How set many EntityKey ?

• .NET: Allow NULLS in DB fields?

  - by mark smith

  Hi there, I have the task of re-factoring an SQLServer DB.... A lot of the tables and columns "ALLOW NULLS", Is this good practice... I seem to remember the authour of CSLA.NET saying it was really bad practice to allow nulls in a DB... If this is the case, what are my alternatives? Remove all "ALLOW NULLS" from all columns.... and in numeric columns use a value of -1 for example?? I would really appreciate any input anyone has. I am currently using a Model (from entity framework) from my DB and the db columns that "ALLOW NULLS" are null ... and some of the stored procedures require that i have a default value... i.e. BOOLEAN require FALSE as default ... but it is null.. Well i don't want to stray from my original question, ALLOW NULLS are a bad thing from what i can gather .... so how do i fix this ? Any help really appreciated

• What is the correct way to create dynamic javascript in ASP.net MVC2?

  I'm creating a Google Maps partial view/user control in my project that is passed a strongly typed list of objects containing latitude and longitude values. Currently, this is the code I have for the partial: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Project.Models.Entities.Location>>" %> <!-- Place for google to put the map --> <div id="report_map_canvas" style="width: 100%; height: 728px; margin-bottom: 2px;"> </div> <script type='text/javascript'> google.load("maps", "2"); $(document).ready(initializeMap); function initializeMap() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById('report_map_canvas')); map.setCenter(new GLatLng(51.5, -0.1167), 2); <% foreach (var item in Model) { %> map.addOverlay(new GMarker(new GLatLng('<%= Html.Encode(item.latitude)%>','<%= Html.Encode(item.longitude)%>'),{ title: '<%= Html.Encode(String.Format("{0:F}",item.speed)) %> km/h '})); <% } %> map.setUIToDefault(); } } </script> Is it right to dynamically create the javascript file this way by looping over the list and emitting javascript? Is there a better way to do it?

• decimal.TryParse() drops leading "1"

  - by Martin Harris

  Short and sweet version: On one machine out of around a hundred test machines decimal.TryParse() is converting "1.01" to 0.01 Okay, this is going to sound crazy but bare with me... We have a client applications that communicates with a webservice through JSON, and that service returns a decimal value as a string so we store it as a string in our model object: [DataMember(Name = "value")] public string Value { get; set; } When we display that value on screen it is formatted to a specific number of decimal places. So the process we use is string - decimal then decimal - string. The application is currently undergoing final testing and is running on more than 100 machines, where this all works fine. However on one machine if the decimal value has a leading '1' then it is replaced by a zero. I added simple logging to the code so it looks like this: Log("Original string value: {0}", value); decimal val; if (decimal.TryParse(value, out val)) { Log("Parsed decimal value: {0}", val); string output = val.ToString(format, CultureInfo.InvariantCulture.NumberFormat); Log("Formatted string value: {0}", output); return output; } On my machine - any every other client machine - the logfile output is: Original string value: 1.010000 Parsed decimal value: 1.010000 Formatted string value: 1.01 On the defective machine the output is: Original string value: 1.010000 Parsed decimal value: 0.010000 Formatted string value: 0.01 So it would appear that the decimal.TryParse method is at fault. Things we've tried: Uninstalling and reinstalling the client application Uninstalling and reinstalling .net 3.5 sp1 Comparing the defective machine's regional settings for numbers (using English (United Kingdom)) to those of a working machine - no differences. Has anyone seen anything like this or has any suggestions? I'm quickly running out of ideas... While I was typing this some more info came in: Passing a string value of "10000" to Convert.ToInt32() returns 0, so that also seems to drop the leading 1.

• Project Architecture For Enhancing Legacy project.

  - by vijay.shad

  I am working on legacy project. Now the situation demands project to be divided into parts. What strategy I should follow to do this task. Description: The legacy project (A) is fully functional web application with almost well defined layers. But now i need to extend the project to a further enhancement. This project usage maven as build tool. But it is used only for dependency managements only. (project exported to war form inside eclipse). The new enhancement needs me to add new data table, new UI(jsp, css, js and images). What should be my strategy to enhance to application. My proposed design. I am planing to create two new projects Project B : Main Enhancement works will done in this project. Will have all layers like service layer, dao layer and UI layer in itself. And will be a web application in itself. Project C : Extract some common model and service code form project-A and create this project. This project will be added as dependency to both the projects. If my this approach is okay! Then i presume there will be problem be problem in deployment. These two projects will demand to deploy separately(currently tomcat is used). But I must deploy these two projects as one war. So, i need to have a plan to change the web.xml entries to have configurations for both projects.

• add new option to dropdownlist after jquery dialog and post

  - by RememberME

  I have a form to enter subcontracts. On this form I have a dropdownlist of all companies in the system. Next to it is a button "Create Company". This button opens a jquery dialog which allows the user to create a new company. Once the dialog closes, the new company needs to be added to the dropdownlist and selected. If I refresh, it's there, but I need to do it without refreshing the form b/c I don't want the user to loose everything that they've entered into the other fields. I'm not sure how to do this b/c I don't have the guid of the new company. My jquery dialog: $('#popupCreateCompany').dialog( { autoOpen: false, modal: true, buttons: { 'Add': function() { var dialog = $(this); var form = dialog.find('input:text, select'); $.post('/company/create', $(form).serialize(), function() { dialog.dialog('close'); }) }, 'Cancel': function() { $(this).dialog('close'); } } }); $("#create-company").click(function() { $('#popupCreateCompany').dialog('open'); }); Company field: <label for="company">Company:</label> <%= Html.DropDownList("company", Model.SelectCompanies, "** Select Company **") %> <%= Html.ValidationMessage("Company", "*") %> <button type="button" id="create-company" >Create Company</button>

• Django's self.client.login(...) does not work in unit tests

  - by thebossman

  I have created users for my unit tests in two ways: 1) Create a fixture for "auth.user" that looks roughly like this: { "pk": 1, "model": "auth.user", "fields": { "username": "homer", "is_active": 1, "password": "sha1$72cd3$4935449e2cd7efb8b3723fb9958fe3bb100a30f2", ... } } I've left out the seemingly unimportant parts. 2) Use 'create_user' in the setUp function (although I'd rather keep everything in my fixtures class): def setUp(self): User.objects.create_user('homer', '[email protected]', 'simpson') Note that the password is simpson in both cases. I've verified that this info is correctly being loaded into the test database time and time again. I can grab the User object using User.objects.get. I can verify the password is correct using 'check_password.' The user is active. Yet, invariably, self.client.login(username='homer', password='simpson') FAILS. I'm baffled as to why. I think I've read every single Internet discussion pertaining to this. Can anybody help? The login code in my unit test looks like this: login = self.client.login(username='homer', password='simpson') self.assertTrue(login) Thanks.

• Blob in Java/Hibernate/sql-server 2005

  - by Ramy

  Hi, I'm trying to insert an HTML blob into our sql-server2005 database. i've been using the data-type [text] for the field the blob will eventually live in. i've also put a '@Lob' annotation on the field in the domain model. The problem comes in when the HTML blob I'm attempting to store is larger than 65536 characters. Its seems that is the caracter-limit for a text data type when using the @Lob annotation. Ideally I'd like to keep the whole blob in tact rather than chunk it up into multiple rows in the database. I appreciate any help or insight that might be provided. Thanks! _Ramy Allow me to clarify annotation: @Lob @Column(length = Integer. MAX_VALUE) //per an answer on stackoverflow private String htmlBlob; database side (sql-server-2005): CREATE TABLE dbo.IndustrySectorTearSheetBlob( ... htmlBlob text NULL ... ) Still seeing truncation after 65536 characters... EDIT: i've printed out the contents of all possible strings (only 10 right now) that would be inserted into the Database. Each string seems to contain all cahracters, judging by the fact that the close html tag is present at the end of the string....
