  • How to get around the Circular Reference issue with JSON and Entity

    - by DanScan
    I have been experimenting with creating a website that leverages MVC with JSON for my presentation layer and Entity framework for data model/database. My Issue comes into play with serializing my Model objects into JSON. I am using the code first method to create my database. When doing the code first method a one to many relationship (parent/child) requires the child to have a reference back to the parent. (Example code my be a typo but you get the picture) class parent { public List<child> Children{get;set;} public int Id{get;set;} } class child { public int ParentId{get;set;} [ForeignKey("ParentId")] public parent MyParent{get;set;} public string name{get;set;} } When returning a "parent" object via a JsonResult a circular reference error is thrown because "child" has a property of class parent. I have tried the ScriptIgnore attribute but I lose the ability to look at the child objects. I will need to display information in a parent child view at some point. I have tried to make base classes for both parent and child that do not have a circular reference. Unfortunately when I attempt to send the baseParent and baseChild these are read by the JSON Parser as their derived classes (I am pretty sure this concept is escaping me). Base.baseParent basep = (Base.baseParent)parent; return Json(basep, JsonRequestBehavior.AllowGet); The one solution I have come up with is to create "View" Models. I create simple versions of the database models that do not include the reference to the parent class. These view models each have method to return the Database Version and a constructor that takes the database model as a parameter (viewmodel.name = databasemodel.name). This method seems forced although it works. NOTE:I am posting here because I think this is more discussion worthy. I could leverage a different design pattern to over come this issue or it could be as simple as using a different attribute on my model. In my searching I have not seen a good method to overcome this problem. My end goal would be to have a nice MVC application that heavily leverages JSON for communicating with the server and displaying data. While maintaining a consistant model across layers (or as best as I can come up with).

  • git workflow for separating commits

    - by gman
    Best practices with git (or any VCS for that matter) is supposed to be to have each commit do the smallest change possible. But, that doesn't match how I work at all. For example I recently I needed to add some code that checked if the version of a plugin to my system matched the versions the system supports. If not print a warning that the plugin probably requires a newer version of the system. While writing that code I decided I wanted the warnings to be colorized. I already had code that colorized error message so I edited that code. That code was in the startup module of one entry to the system. The plugin checking code was in another path that didn't use that entry point so I moved the colorization code into a separate module so both entry points could use it. On top of that, in order to test my plugin checking code works I need to go edit UI/UX code to make sure it tells the user "You need to upgrade". When all is said and done I've edited 10 files, changed dependencies, the 2 entry points are now both dependant on the colorization code, etc etc. Being lazy I'd probably just git add . && git commit -a the whole thing. Spending 10-15 minutes trying to manipulate all those changes into 3 to 6 smaller commits seems frustrating which brings up the question Are there workflows that work for you or that make this process easier? I don't think I can some how magically always modify stuff in the perfect order since I don't know that order until after I start modifying and seeing what comes up. I know I can git add --interactive etc but it seems, at least for me, kind of hard to know what I'm grabbing exactly the correct changes so that each commit is actually going to work. Also, since the changes are sitting in the current directory it doesn't seem like it would be easy to run tests on each commit to make sure it's going to work short of stashing all the changes. And then, if it were to stash and then run the tests, if I missed a few lines or accidentally added a few too many lines I have no idea how I'd easily recover from that. (as in either grab the missing lines from the stash and then put the rest back or take the few extra lines I shouldn't have grabbed and shove them into the stash for the next commit. Thoughts? Suggestions? PS: I hope this is an appropriate question. The help says development methodologies and processes

  • Summary of our Recent Pull Request Enhancements on CodePlex

    Over the past several weeks, we’ve been incrementally rolling out a bunch of enhancements around our pull request workflow for Git and Mercurial projects. Our goal is to make contributing to open source projects a simple and rewarding experience, and we’ll continue to invest in this area. Here’s a summary of the changes so far, in case you’ve missed them. As always, if you have any feedback, please let us know, whether on our ideas page or via Twitter. Support for branches You can now pick the source and destination branches for your pull request, whether you’re sending one from your fork, or using it within a project to collaborate with your other trusted contributors. A redesigned creation experience Our old pull request creation form was rather lacking. It asked for a title and comment in a small modal dialog, but that was about it. We knew we could do better, so we rethought the experience. Now, when you create a pull request, you’re taken to a new page that let’s you select the source and destination, and gives you information on the diffs and commits that you’re sending, so you can confirm that you’re sending the right set of changes. Inline code snippets in discussion If users comment on code in your pull request, we now display a preview of the snippet of relevant code inline with their comment on the discussion. Subsequent replies on that line are combined in a single thread to preserve your context. No more clicking and hunting to find where the comments are. And you can add another inline comment right from the discussion area. Comment notifications You can now elect receive an e-mail notification if a user comments on your pull request. If it’s on a line of code, we’ll display the relevant code snippet in the e-mail. Redesigned diff viewer Our old diff viewer hadn’t been touched in a while, and was in need of an update. We started with a visual facelift to use standard red/green colors for additions/deletions and remove the noisy “dots” that represented spaces and that littered the diff viewer. Based on feedback that the viewable region for diffs was too small, especially for smaller screen resolutions, we revamped the way the viewport for the code is sized, and now expand it to fill the majority of the browser height when scrolling down. The set of improvements we implemented here also apply anywhere diffs are viewed, not just for pull requests.

    Following is the code. create a class lib add the ref to NUnit framework 2.5.3.9345 and Moq.dll 4.0.0.0 and paste the following code. Try running it on my machine it throws TestCase 'MoqTest.TryClassTest.IsMessageNotNull' failed: Moq.MockException : Expected invocation on the mock at least once, but was never performed: v = v.Model = It.Is(value(Moq.It+<c__DisplayClass21[MoqTest.GenInfo]).match) at Moq.Mock.ThrowVerifyException(IProxyCall expected, Expression expression, Times times, Int32 callCount) at Moq.Mock.VerifyCalls(Interceptor targetInterceptor, MethodCall expected, Expression expression, Times times) at Moq.Mock.VerifySet[T](Mock1 mock, Action1 setterExpression, Times times, String failMessage) at Moq.Mock1.VerifySet(Action`1 setterExpression) Class1.cs(22,0): at MoqTest.TryClassTest.IsMessageNotNull() using System; using System.Collections.Generic; using System.Linq; using System.Text; using Moq; using NUnit.Framework; namespace MoqTest { [TestFixture] public class TryClassTest { [Test] public void IsMessageNotNull() { var mockView = new Mock<IView<GenInfo>>(); mockView.Setup(v => v.ModuleId).Returns(""); TryPresenter tryPresenter = new TryPresenter(mockView.Object); tryPresenter.SetMessage(new object(), new EventArgs()); // mockView.VerifySet(v => v.Message, Times.AtLeastOnce()); mockView.VerifySet(v => v.Model = It.Is<GenInfo>(x => x != null)); } } public class TryPresenter { private IView<GenInfo> view; public TryPresenter(IView<GenInfo> view) { this.view = view; } public void SetMessage(object sender, EventArgs e) { this.view.Model = null; } } public class MyView : IView<GenInfo> { #region Implementation of IView<GenInfo> public string ModuleId { get; set; } public GenInfo Model { get; set; } #endregion } public interface IView<T> { string ModuleId { get; set; } T Model { get; set; } } public class GenInfo { public String Message { get; set; } } } And if you change one line mockView.VerifySet(v = v.Model = It.Is(x = x != null)); to mockView.VerifySet(v = v.Model, Times.AtLeastOnce()); it works fine. I think Exception is incorrect.

  • Attempting to update multiple partial views from a single Ajax.ActionLink

    - by mwright
    I have a a partial view which contains other partial views. I am trying to the main partial view ( "MainPartialView" ) from an Ajax.ActionLink in a partial view contained by the main partial view ( "DetailsView" ). Everything appears to be called just fine and I can step through and it executes all of the code on the pages. However, after that is all done it throws this error in a popup box in visual studio: htmlfile: Unknown runtime error This error puts the break point in the MicrosoftAjax.js file, Line 5, Col 83,632, Ch 83632. Any thoughts?

  • MVC 2 View Layout CSS Control Layout

    - by Cory Mathewson
    I'm new to a lot of what I'm trying to do with the development of a new MVC2 web application so this is a beginner question. I need to understand my options for control and content layout on a web page. I’m using MVC2 so I’m using Controllers, Views, ViewModels, and View Templates. What I need to spin up on…fast…is control the granular layout of controls and content on any particular view. Below I’ve pasted two examples of auto generated templates that illustrate my challenge. I see that layout is controlled by CSS in my Site.css document. In the first example I get a sequential flow of DisplayLabel and DisplayField. I prefer the adjacent layout of DisplayLabel on the same line as DisplayField produced from example 2. However, example 2 is too simple because the formatting is applied to the Label and the Field. I think the correct way to tackle this learning curve is Microsoft Expression but I don’t have personal bandwidth at the moment to tackle Expression. Can anyone point me to a resource that will expose me to lots of examples for CSS formatting? I have lots of syntax questions. For instance, I believe is referencing the Site.css but I can’t find a "display-label" section in Site.css. Example 1 <fieldset> <legend>Fields</legend> <div class="display-label">DocTitle</div> <div class="display-field"><%: Model.DocTitle %></div> <div class="display-label">DocoumentPropertiesID</div> <div class="display-field"><%: Model.DocumentPropertiesID %></div> Example 2 <h2>Title: <%: Model.DocTitle %></h2> <h2>Created: <%: Model.Created %></h2> <h2>Modified: <%: Model.Modified %></h2> <h2>Author: <%: Model.tbl_Author.Name %></h2> <h2>Genre: <%: Model.tbl_DocumentGenre.GenreName %></h2>
