MVC :: Store Model In Separate Class Library- Pass Model Objects?
May 19, 2010I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?
Default Model Binder Does Not Bind Model Class
Dec 28, 2010I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted
<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>
This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });
This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }
But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.
MVC :: Post Action Model Parameter
Jan 26, 2011i wonder something about mvc post method. for example I created a view "strongly typed" from a model (MyModel).
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Demo1.Models.MyModel>" %>
for Create actionsthere is two way.
first one takes MyModel as parameter
[HttpPost]
public ActionResult cart(MyModel md, int someID)
{
//some code
//.....
return View(MyModel);
}
second one does not take parameter as model.
[HttpPost]
public ActionResult cart(int someID)
{
//some code
//.....
return View(Mymodel);
}
for first one way, after form post the form values does not delete, I mean form does not cleared,after second one form is be cleared. why this diffirence?

C# - MVC - Using Model Property As Form - Post To Action?
Jan 12, 2011public class BandProfileModel
{
public BandModel Band { get; set; }
public IEnumerable<Relationship> Requests { get; set; }
}
and the following form:
<% using (Html.BeginForm()) { %>
<%: Html.EditorFor(m => m.Band) %>
<input type="submit" value="Save Band" />
<% } %>
which posts to the following action:
public ActionResult EditPost(BandProfileModel m, string band)
{
// stuff is done here, but m is null?
return View(m);
}
Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null). It's posting just fine to the action, so it isn't a problem with my route. Just the data is null.
The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work. What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action?
MVC :: Action Method Taking Model Object?

MVC :: Updating Another Model - Catch Form Submit In Details Action In PostController?
Feb 6, 2011Having alot of startup issues with MVC - I really like the idea behind it all, and the way it works, but still lacking some essential skills, WebForms is much more natural to me. Just to simplify my problem.

Maybe referencing the MVC equivalant of HttpContext.Current like I used to do in WebForms?

MVC :: Is Model A Entity Class Type
Feb 12, 2010I have some questions in my mind after went through the video tutorials.

Is it a good practice to generate Model using LINQ?
MVC :: Can't Reference To Some Properties In Model Class
Mar 31, 2010I'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.
[Code]....
and the error message
Compiler Error Message:
CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.

Jan 4, 2010I just struck upon a prime opportunity to further exhibit my MVC ignorance, by way of the following: How can one make use of a custom view model class that has parameters in the constructor? For example, a class that could intitialize various collections/properties based on an IPrincipal object passed in. I've come across several allusions to this scenario, involving a class inheriting DefaultModelBinder which overrides the CreateModel method, but have yet to find an example.
