  • Rails Associations - Callback Sequence/Magic

    - by satynos
    Taking following association declaration as an example: class Post has_many :comments end Just by declaring the has_many :comments, ActiveRecord adds several methods of which I am particularly interested in comments which returns array of comments. I browsed through the code and following seems to be the callback sequence: def has_many(association_id, options = {}, &extension) reflection = create_has_many_reflection(association_id, options, &extension) configure_dependency_for_has_many(reflection) add_association_callbacks(reflection.name, reflection.options) if options[:through] collection_accessor_methods(reflection, HasManyThroughAssociation) else collection_accessor_methods(reflection, HasManyAssociation) end end def collection_accessor_methods(reflection, association_proxy_class, writer = true) collection_reader_method(reflection, association_proxy_class) if writer define_method("#{reflection.name}=") do |new_value| # Loads proxy class instance (defined in collection_reader_method) if not already loaded association = send(reflection.name) association.replace(new_value) association end define_method("#{reflection.name.to_s.singularize}_ids=") do |new_value| ids = (new_value || []).reject { |nid| nid.blank? } send("#{reflection.name}=", reflection.class_name.constantize.find(ids)) end end end def collection_reader_method(reflection, association_proxy_class) define_method(reflection.name) do |*params| force_reload = params.first unless params.empty? association = association_instance_get(reflection.name) unless association association = association_proxy_class.new(self, reflection) association_instance_set(reflection.name, association) end association.reload if force_reload association end define_method("#{reflection.name.to_s.singularize}_ids") do if send(reflection.name).loaded? || reflection.options[:finder_sql] send(reflection.name).map(&:id) else send(reflection.name).all(:select => "#{reflection.quoted_table_name}.#{reflection.klass.primary_key}").map(&:id) end end end In this sequence of callbacks, where exactly is the actual SQL being executed for retrieving the comments when I do @post.comments ?

  • How to Process Lambda Expressions Passed as Argument Into Method - C# .NET 3.5

    - by Sunday Ironfoot
    My knowledge of Lambda expressions is a bit shaky, while I can write code that uses Lambda expressions (aka LINQ), I'm trying to write my own method that takes a few arguments that are of type Lambda Expression. Background: I'm trying to write a method that returns a Tree Collection of objects of type TreeItem from literally ANY other object type. I have the following so far: public class TreeItem { public string Id { get; set; } public string Text { get; set; } public TreeItem Parent { get; protected set; } public IList<TreeItem> Children { get { // Implementation that returns custom TreeItemCollection type } } public static IList<TreeItem> GetTreeFromObject<T>(IList<T> items, Expression<Func<T, string>> id, Expression<Func<T, string>> text, Expression<Func<T, IList<T>>> childProperty) where T : class { foreach (T item in items) { // Errrm!?? What do I do now? } return null; } } ...which can be called via... IList<TreeItem> treeItems = TreeItem.GetTreeFromObject<Category>( categories, c => c.Id, c => c.Name, c => c.ChildCategories); I could replace the Expressions with string values, and just use reflection, but I'm trying to avoid this as I want to make it strongly typed. My reasons for doing this is that I have a control that accepts a List of type TreeItem, whereas I have dozens of different types that are all in a tree like structure, and don't want to write seperate conversion methods for each type (trying to adhere to the DRY principle). Am I going about this the right way? Is there a better way of doing this perhaps?

  • Could not load type from assembly error

    - by George Mauer
    I have written the following simple test in trying to learn Castle Windsor's Fluent Interface: using NUnit.Framework; using Castle.Windsor; using System.Collections; using Castle.MicroKernel.Registration; namespace WindsorSample { public class MyComponent : IMyComponent { public MyComponent(int start_at) { this.Value = start_at; } public int Value { get; private set; } } public interface IMyComponent { int Value { get; } } [TestFixture] public class ConcreteImplFixture { [Test] public void ResolvingConcreteImplShouldInitialiseValue() { IWindsorContainer container = new WindsorContainer(); container.Register(Component.For<IMyComponent>().ImplementedBy<MyComponent>().Parameters(Parameter.ForKey("start_at").Eq("1"))); IMyComponent resolvedComp = container.Resolve<IMyComponent>(); Assert.AreEqual(resolvedComp.Value, 1); } } } When I execute the test through TestDriven.NET I get the following error: System.TypeLoadException : Could not load type 'Castle.MicroKernel.Registration.IRegistration' from assembly 'Castle.MicroKernel, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc'. at WindsorSample.ConcreteImplFixture.ResolvingConcreteImplShouldInitialiseValue() When I execute the test through the NUnit GUI I get: WindsorSample.ConcreteImplFixture.ResolvingConcreteImplShouldInitialiseValue: System.IO.FileNotFoundException : Could not load file or assembly 'Castle.Windsor, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc' or one of its dependencies. The system cannot find the file specified. If I open the Assembly that I am referencing in Reflector I can see its information is: Castle.MicroKernel, Version=1.0.3.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc and that it definitely contains Castle.MicroKernel.Registration.IRegistration What could be going on? I should mention that the binaries are taken from the latest build of Castle though I have never worked with nant so I didn't bother re-compiling from source and just took the files in the bin directory. I should also point out that my project compiles with no problem.

    - by jitm
    Hello, I've created the test self-hosted wcf application and tried to add support https.

Thanks.

  • Problem with Mapping Linq-to-Sql on different Types

    - by csharpnoob
    Hi, maybe someone can help. I want to have on mapped Linq-Class different Datatype. This is working: private System.Nullable<short> _deleted = 1; [Column(Storage = "_deleted", Name = "deleted", DbType = "SmallInt", CanBeNull = true)] public System.Nullable<short> deleted { get { return this._deleted; } set { this._deleted = value; } } Sure thing. But no when i want to place some logic for boolean, like this: private System.Nullable<short> _deleted = 1; [Column(Storage = "_deleted", Name = "deleted", DbType = "SmallInt", CanBeNull = true)] public bool deleted { get { if (this._deleted == 1) { return true; } return false; } set { if(value == true) { this._deleted = (short)1; }else { this._deleted = (short)0; } } } I get always runtime error: [TypeLoadException: GenericArguments[2], "System.Nullable`1[System.Int16]", on 'System.Data.Linq.Mapping.PropertyAccessor+Accessor`3[T,V,V2]' violates the constraint of type parameter 'V2'.] I can't change the database to bit.. I need to have casting in mapping class.

  • HTTPWebResponse returning no content

    - by Richard Yale
    Our company works with another company called iMatrix and they have an API for creating our own forms. They have confirmed that our request is hitting their servers but a response is supposed to come back in 1 of a few ways determined by a parameter. I'm getting a 200 OK response back but no content and a content-length of 0 in the response header. here is the url: https://secure4.office2office.com/designcenter/api/imx_api_call.asp I'm using this class: namespace WebSumit { public enum MethodType { POST = 0, GET = 1 } public class WebSumitter { public WebSumitter() { } public string Submit(string URL, Dictionary<string, string> Parameters, MethodType Method) { StringBuilder _Content = new StringBuilder(); string _ParametersString = ""; // Prepare Parameters String foreach (KeyValuePair<string, string> _Parameter in Parameters) { _ParametersString = _ParametersString + (_ParametersString != "" ? "&" : "") + string.Format("{0}={1}", _Parameter.Key, _Parameter.Value); } // Initialize Web Request HttpWebRequest _Request = (HttpWebRequest)WebRequest.Create(URL); // Request Method _Request.Method = Method == MethodType.POST ? "POST" : (Method == MethodType.GET ? "GET" : ""); _Request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Win32)"; // Send Request using (StreamWriter _Writer = new StreamWriter(_Request.GetRequestStream(), Encoding.UTF8)) { _Writer.Write(_ParametersString); } // Initialize Web Response HttpWebResponse _Response = (HttpWebResponse)_Request.GetResponse(); // Get Response using (StreamReader _Reader = new StreamReader(_Response.GetResponseStream(), Encoding.UTF8)) { _Content.Append(_Reader.ReadToEnd()); } return _Content.ToString(); } } } I cannot post the actual parameters because they are to the live system, but can you look at this code and see if there is anything that is missing? Thanks!

  • Show Add button after Edit button is clicked?

    - by David.Chu.ca
    I have a view with navigation bar control on the top. The view is in the second level with a "back" button is displayed on the left by default. In my view class, I added a default navigation edit button on the right: self.navigationbarItem.rightButtonItem = self.editButtonItem; with this line of code, an edit button is on the right side, and when it is clicked, the view (table view) becomes editable with delete mark on the left for each row. After that, the edit button's caption becomes "done". All those are done by the default edit button built in the navigation control, I think. I would like to add an add button the left, or replace "back" button when edit is clicked. I guess I have to implement some kind of delegate in my view class. This would provide a place to plug in my code to add the add button on the left when edit button is clicked, and to restore "back" button back when the done button is clicked. If so, what's the delegate? Or is there any other way to achieve it?

  • Why a Swing app stops my Java servlet ?

    - by Frank
    I have a Swing runnable app which updates messages, then I have a Java servlet that gets messages from Paypal IPN (Instant Payment Notification), when the servlet starts up, in the init(), I starts the Swing runnable app which opens a desktop window, but 30 minutes later an error in the Swing caused the servlet to stop, how can that happen ? Because the runnable is running on it's own thread, servlet started that thread, why an error in that thread will cause the servlet to stop ? public class License_Manager extends JPanel implements Runnable { License_Manager() { Do_GUI(); ... start(); } public static void main(String[] args) { // Schedule a job for the event-dispatching thread : creating and showing this application's GUI. javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { Create_And_Show_GUI(); } }); } } public class PayPal_Servlet extends HttpServlet { public void init(ServletConfig config) throws ServletException { super.init(config); License_Manager.main(null); } protected void processRequest(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { } } And besides the error don't even have anything to do with my code, it looks like this : Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 17 = 0 at java.util.Vector.elementAt(Vector.java:427) at javax.swing.DefaultListModel.getElementAt(DefaultListModel.java:70) at javax.swing.plaf.basic.BasicListUI.paintCell(BasicListUI.java:191) at javax.swing.plaf.basic.BasicListUI.paintImpl(BasicListUI.java:304) at javax.swing.plaf.basic.BasicListUI.paint(BasicListUI.java:227) at javax.swing.plaf.ComponentUI.update(ComponentUI.java:143) at javax.swing.JComponent.paintComponent(JComponent.java:763) at javax.swing.JComponent.paint(JComponent.java:1029) at javax.swing.JComponent.paintChildren(JComponent.java:864) at javax.swing.JComponent.paint(JComponent.java:1038) at javax.swing.JViewport.paint(JViewport.java:747) at javax.swing.JComponent.paintChildren(JComponent.java:864) at javax.swing.JComponent.paint(JComponent.java:1038) at javax.swing.JComponent.paintToOffscreen(JComponent.java:5124) at javax.swing.BufferStrategyPaintManager.paint(BufferStrategyPaintManager.java:278) at javax.swing.RepaintManager.paint(RepaintManager.java:1220) at javax.swing.JComponent._paintImmediately(JComponent.java:5072) at javax.swing.JComponent.paintImmediately(JComponent.java:4882) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:803) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:714) at javax.swing.RepaintManager.seqPaintDirtyRegions(RepaintManager.java:694) at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(SystemEventQueueUtilities.java:128) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

  • Remove appearance of TextField in droidText : Android

    - by AnujAroshA
    I am trying to create a PDF using droidText library. There I want to place some text content in the middle of the page but align to left. I was unable to do with Paragraph class and setAlignment() method. So I have decided to use TextField class. Below is the code I have used, Document document = new Document(PageSize.A4); try { PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(android.os.Environment.getExternalStorageDirectory() + java.io.File.separator + "TextFields.pdf")); document.open(); TextField tf = new TextField(writer, new Rectangle(100, 300, 200, 350), "Content"); tf.setText("This is the content of text field"); tf.setAlignment(Element.ALIGN_CENTER); tf.setOptions(TextField.MULTILINE | TextField.REQUIRED); PdfFormField field = tf.getTextField(); writer.addAnnotation(field); } catch (DocumentException de) { System.err.println(de.getMessage()); } catch (IOException ioe) { System.err.println(ioe.getMessage()); } document.close(); Code works perfect, but the out put PDF file that I am getting has this TextField which can be editable and also change the font appearance when I am click on the TextField. I don't want that in to my final PDF. How can I remove that attribute? If it is not possible, is there any other way I can position some text in a PDF file using droidText library in Android?

  • NHibernate query with Projections.Cast to DateTime

    - by stiank81
    I'm experimenting with using a string for storing different kind of data types in a database. When I do queries I need to cast the strings to the right type in the query itself. I'm using .Net with NHibernate, and was glad to learn that there exists functionality for this. Consider the simple class: public class Foo { public string Text { get; set; } } I successfully use Projections.Cast to cast to numeric values, e.g. the following query correctly returns all Foos with an interger stored as int - between 1-10. var result = Session.CreateCriteria<Foo>() .Add(Restrictions.Between(Projections.Cast(NHibernateUtil.Int32, Projections.Property("Text")), 1, 10)) .List<Foo>(); Now if I try using this for DateTime I'm not able to make it work no matter what I try. Why?! var date = new DateTime(2010, 5, 21, 11, 30, 00); AddFooToDb(new Foo { Text = date.ToString() } ); // Will add it to the database... var result = Session .CreateCriteria<Foo>() .Add(Restrictions.Eq(Projections.Cast(NHibernateUtil.DateTime, Projections.Property("Text")), date)) .List<Foo>();

  • JSF Page does not submit when onclick javascript is added to menu item?

    - by Padmarag
    I show some detail using popup windows. I want to close those when the user clicks on sign-out link. I have a JavaScript function that'll close the windows. The sign-out link is rendered using Navigation MenuModel. The definition in faces-config is as below - <managed-bean> <managed-bean-name>signoutNavigation</managed-bean-name> <managed-bean-class>com.xxx.xxx.framework.NavigationItem</managed-bean-class> <managed-bean-scope>none</managed-bean-scope> <managed-property> <property-name>label</property-name> <value>Sign Out</value> </managed-property> <managed-property> <property-name>viewId</property-name> <value>/signout.jsp</value> </managed-property> <managed-property> <property-name>outcome</property-name> <value>signout</value> </managed-property> <managed-property> <property-name>onclick</property-name> <value>closeOrderWindows()</value> </managed-property> </managed-bean> The problem is when I use the "onclick" property on managed-bean, the page doesn't submit to "signout.jsp" and remains on same page. When I remove/comment the "onclick" part, the page gets submitted properly. I use MyFaces Trinidad.

  • Fluent nhibernate: Enum in composite key gets mapped to int when I need string

    - by Quintin Par
    By default the behaviour of FNH is to map enums to its string in the db. But while mapping an enum as part of a composite key, the property gets mapped as int. e.g. in this case public class Address : Entity { public Address() { } public virtual AddressType Type { get; set; } public virtual User User { get; set; } Where AddresType is of public enum AddressType { PRESENT, COMPANY, PERMANENT } The FNH mapping is as mapping.CompositeId().KeyReference(x => x.User, "user_id").KeyProperty(x => x.Type); the schema creation of this mapping results in create table address ( Type INTEGER not null, user_id VARCHAR(25) not null, and the hbm as <composite-id mapped="true" unsaved-value="undefined"> <key-property name="Type" type="Company.Core.AddressType, Company.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <column name="Type" /> </key-property> <key-many-to-one name="User" class="Company.Core.CompanyUser, Company.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <column name="user_id" /> </key-many-to-one> </composite-id> Where the AddressType should have be generated as type="FluentNHibernate.Mapping.GenericEnumMapper`1[[Company.Core.AddressType, How do I instruct FNH to mappit as the default string enum generic mapper?

  • WCF Datacontract, some fields do not deserialize

    - by jhersh
    Problem: I have a WCF service setup to be an endpoint for a call from an external system. The call is sending plain xml. I am testing the system by sending calls into the service from Fiddler using the RequestBuilder. The issue is that all of my fields are being deserialized with the exception of two fields. price_retail and price_wholesale. What am I missing? All of the other fields deserialize without an issue - the service responds. It is just these fields. XML Message: <widget_conclusion> <list_criteria_id>123</list_criteria_id> <list_type>consumer</list_type> <qty>500</qty> <price_retail>50.00</price_retail> <price_wholesale>40.00</price_wholesale> <session_id>123456789</session_id> </widget_conclusion> Service Method: public string WidgetConclusion(ConclusionMessage message) { var priceRetail = message.PriceRetail; } Message class: [DataContract(Name = "widget_conclusion", Namespace = "")] public class ConclusionMessage { [DataMember(Name = "list_criteria_id")] public int CriteriaId { get; set;} [DataMember(Name = "list_type")] public string ListType { get; set; } [DataMember(Name = "qty")] public int ListQuantity { get; set; } [DataMember(Name = "price_retail")] public decimal PriceRetail { get; set; } [DataMember(Name = "price_wholesale")] public decimal PriceWholesale { get; set; } [DataMember(Name = "session_id")] public string SessionId { get; set; } }

  • Binding from View-Model to View-Model of a child User Control in Silverlight? 2 sources - 1 target..

    - by andrej351
    Hi there, So i have a UserControl for one of my Views and have another 'child' UserControl inside that. The outer 'parent' UserControl has a Collection on its View-Model and a Grid control on it to display a list of Items. I want to place another UserControl inside this UserControl to display a form representing the details of one Item. The outer / parent UserControl's View-Model already has a property on it to hold the currently selected Item and i would like to bind this to a DependancyProperty on the inner / child UserControl. I would then like to bind that DependancyProperty to a property on the child UserControl's View-Model. I can then set the DependancyProperty once in XAML with a binding expression and have the child UserControl do all its work in its View-Model like it should. The code i have looks like this.. Parent UserControl: <UserControl x:Class="ItemsListView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding Source={StaticResource ServiceLocator}, Path=ItemsListViewModel}"> <!-- Grid Control here... --> <ItemDetailsView Item="{Binding Source={StaticResource ServiceLocator}, Path=ItemsListViewModel.SelectedItem}" /> </UserControl> Child UserControl: <UserControl x:Class="ItemDetailsView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding Source={StaticResource ServiceLocator}, Path=ItemDetailsViewModel}" ItemDetailsView.Item="{Binding Source={StaticResource ServiceLocator}, Path=ItemDetailsViewModel.Item, Mode=TwoWay}"> <!-- Form controls here... --> </UserControl> The selected Item is bound to the DependancyProperty fine. However from the DependancyProperty to the child View-Model does not. It appears to be a situation where there are two concurrent bindings which need to work but with the same target for two sources. Why won't the second (in the child UserControl) binding work?? Is there a way to acheive the behaviour I'm after?? Cheers.

  • Process: Unable to start service com.google.android.gms.checkin.CheckinService with Intent

    - by AndyRoid
    I'm trying to build a Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.google.android.gms.checkin A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener.

  • How can I get PowerShell Added-Types to use Added Types

    - by Scott Weinstein
    I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

  • Complex Types, ModelBinders and Interfaces

    - by Kieron
    Hi, I've a scenario where I need to bind to an interface - in order to create the correct type, I've got a custom model binder that knows how to create the correct concrete type (which can differ). However, the type created never has the fields correctly filled in. I know I'm missing something blindingly simple here, but can anyone tell me why or at least what I need to do for the model binder to carry on it's work and bind the properties? public class ProductModelBinder : DefaultModelBinder { override public object BindModel (ControllerContext controllerContext, ModelBindingContext bindingContext) { if (bindingContext.ModelType == typeof (IProduct)) { var content = GetProduct (bindingContext); return content; } var result = base.BindModel (controllerContext, bindingContext); return result; } IProduct GetProduct (ModelBindingContext bindingContext) { var idProvider = bindingContext.ValueProvider.GetValue ("Id"); var id = (Guid)idProvider.ConvertTo (typeof (Guid)); var repository = RepositoryFactory.GetRepository<IProductRepository> (); var product = repository.Get (id); return product; } } The Model in my case is a complex type that has an IProduct property, and it's those values I need filled in. Model: [ProductBinder] public class Edit : IProductModel { public Guid Id { get; set; } public byte[] Version { get; set; } public IProduct Product { get; set; } }

  • Django one form for two models

    - by martinthenext
    Hello! I have a ForeignKey relationship between TextPage and Paragraph and my goal is to make front-end TextPage creating/editing form as if it was in ModelAdmin with 'inlines': several field for the TextPage and then a couple of Paragraph instances stacked inline. The problem is that i have no idea about how to validate and save that: @login_required def textpage_add(request): profile = request.user.profile_set.all()[0] if not (profile.is_admin() or profile.is_editor()): raise Http404 PageFormSet = inlineformset_factory(TextPage, Paragraph, extra=5) if request.POST: try: textpageform = TextPageForm(request.POST) # formset = PageFormSet(request.POST) except forms.ValidationError as error: textpageform = TextPageForm() formset = PageFormSet() return render_to_response('textpages/manage.html', { 'formset' : formset, 'textpageform' : textpageform, 'error' : str(error), }, context_instance=RequestContext(request)) # Saving data if textpageform.is_valid() and formset.is_valid(): textpageform.save() formset.save() return HttpResponseRedirect(reverse(consults)) else: textpageform = TextPageForm() formset = PageFormSet() return render_to_response('textpages/manage.html', { 'formset' : formset, 'textpageform' : textpageform, }, context_instance=RequestContext(request)) I know I't a kind of code-monkey style to post code that you don't even expect to work but I wanted to show what I'm trying to accomplish. Here is the relevant part of models.py: class TextPage(models.Model): title = models.CharField(max_length=100) page_sub_category = models.ForeignKey(PageSubCategory, blank=True, null=True) def __unicode__(self): return self.title class Paragraph(models.Model): article = models.ForeignKey(TextPage) title = models.CharField(max_length=100, blank=True, null=True) text = models.TextField(blank=True, null=True) def __unicode__(self): return self.title Any help would be appreciated. Thanks!

  • Notifying view controller when subview touch events occur.

    - by Nebs
    I have a UIViewController whose view has a custom subview. This custom subview needs to track touch events and report swipe gestures. Currently I put touchesBegan, touchesMoved, touchesEnded and touchesCancelled in the subview class. With some extra logic I am able to get swipe gestures and call my handleRightSwipe and handleLeftSwipe methods. So now when I swipe within the subview it calls its local swipe handling methods. This all works fine. But what I really need is for the handleRightSwipe and handleLeftSwipe methods to be in the view controller. I could leave them in the subview class but then I'd have to bring in all the logic and data as well and that kind of breaks the MVC idea. So my question is is there a clean way to handle this? Essentially I want to keep my touch event methods in the subview so that they only trigger for that specific view. But I also want the view controller to be informed when these touch events (or in this case swipe gestures) occur. Any ideas? Thanks.

  • Need help using the DefaultModelBinder for a nested model.

    - by Will
    There are a few related questions, but I can't find an answer that works. Assuming I have the following models: public class EditorViewModel { public Account Account {get;set;} public string SomeSimpleStuff {get;set;} } public class Account { public string AccountName {get;set;} public int MorePrimitivesFollow {get;set;} } and a view that extends ViewPage<EditorViewModel> which does the following: <%= Html.TextBoxFor(model => model.Account.AccountName)%> <%= Html.ValidationMessageFor(model => model.Account.AccountName)%> <%= Html.TextBoxFor(model => model.SomeSimpleStuff )%> <%= Html.ValidationMessageFor(model => model.SomeSimpleStuff )%> and my controller looks like: [HttpPost] public virtual ActionResult Edit(EditorViewModel account) { /*...*/ } How can I get the DefaultModelBinder to properly bind my EditorViewModel? Without doing anything special, I get an empty instance of my EditorViewModel with everything null or default. The closest I've come is by calling UpdateModel manually: [HttpPost] public virtual ActionResult Edit(EditorViewModel account) { account.Account = new Account(); UpdateModel(account.Account, "Account"); // this kills me: UpdateModel(account); This successfully updates my Account property model, but when I call UpdateModel on account (to get the rest of the public properties of my EditorViewModel) I get the completely unhelpful "The model of type ... could not be updated." There is no inner exception, so I can't figure out what's going wrong. What should I do with this?
