All geek questions in one place

MVC runs one HttpPost editor, the other does not. What am I missing?

Googling in general and on SO has not yet helped me, therefore:

I create my first MVC application from scratch by going to the MVC Music Store example , but instead I create a small application where the Fighters arena can be created and created to fight each other. ( Fightersand Fightwere linked to base tables via EF).

I have controllers for Fightersand Fights. Edit Actionresultfor Fightsworks, but for Fightersit is not. When I click the button to save the changes, I return to the corresponding page of the Index, but there were no changes. This is my question: why is this failing?

From BarracksController , with incorrect HttpPost Edit update (should have been called FighterController, but not true):

        //
        // GET: /Barracks/Edit
        public ActionResult Edit(int id)
        {
            ViewData.Model = _FightDb.Fighters.Single(f => f.Id == id);
            return View();
        }


        //
        // POST: /Barracks/Edit
        [HttpPost]
        public ActionResult Edit(int id, FormCollection collection)
        {
            var fighter = _FightDb.Fighters.Single(f => f.Id == id);

            try
            {
                UpdateModel(fighter, "Fighter");
                var x = ViewData.GetModelStateErrors();
                _FightDb.SaveChanges();

                return RedirectToAction("Index");
            }
            catch
            {
                var viewModel = fighter;

                return View(viewModel);
            }

        }

(As you can see, I included the GetModelStateErrors trick from this SO question , but the result for x is equal null)

This is the controller that works, FightController:

   //
        // GET: /Fights/Edit
        public ActionResult Edit(int id)
        {
            var viewModel = new FightDetailsViewModel
            {
                Fight = _FightDb.Fights.Single(f => f.ID == id),
                Fighters = _FightDb.Fighters.ToList()
            };

            return View(viewModel);
        }

        //
        // POST: /Fights/Edit
        [HttpPost]
        public ActionResult Edit(int id, FormCollection collection)
        {
            var fight = _FightDb.Fights.Single(f => f.ID == id);

            try
            {
                UpdateModel(fight, "Fight");
                _FightDb.SaveChanges();

                return RedirectToAction("Index");
            }
            catch
            {
                var viewModel = new FightDetailsViewModel
                {
                    Fight = _FightDb.Fights.Single(f => f.ID == id),
                    Fighters = _FightDb.Fighters.ToList()
                };

                return View(viewModel);
            }
        }

This is edit.aspx for fighters: (Edited after comment)

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Mvc3_EF_BW_Fight.Models.Fighter>" %>


<asp:Content ID="Content1" ContentPlaceHolderID="cphMain" runat="server">
    <h2>Edit</h2>

        <%: Html.EditorForModel()  %>

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="head" runat="server">
</asp:Content>

What uses the following Fighter.ascx in Shared:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Mvc3_EF_BW_Fight.Models.Fighter>" %>
<% using (Html.BeginForm())
   {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
    <legend>Fighter</legend>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Id) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.Id) %>
        <%: Html.ValidationMessageFor(model => model.Id) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.FighterName) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.FighterName) %>
        <%: Html.ValidationMessageFor(model => model.FighterName) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.FighterStyleDescription) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.FighterStyleDescription) %>
        <%: Html.ValidationMessageFor(model => model.FighterStyleDescription) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.FighterLongDescription) %>
    </div>
    <div class="editor-field">
        <%: Html.TextAreaFor(model => model.FighterLongDescription) %>
        <%: Html.ValidationMessageFor(model => model.FighterLongDescription) %>
    </div>
    <p>
        <input type="submit" value="Save" />
    </p>
</fieldset>
<% } %>

This is edit.aspx for fights

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Mvc3_EF_BW_Fight.ViewModels.FightDetailsViewModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="cphMain" runat="server">

    <h2>Edit</h2>
    <%: Html.EditorFor(model => model.Fight, new { Fighters = Model.Fighters })%>

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="head" runat="server">
</asp:Content>

And this is Fight.ascx:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Mvc3_EF_BW_Fight.Models.Fight>" %>
<% using (Html.BeginForm())
   {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
    <legend>Fields</legend>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.ID) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.ID) %>
        <%: Html.ValidationMessageFor(model => model.ID) %>
    </div>


    <div class="editor-label">
        <%: Html.LabelFor(model => model.FightName) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.FightName) %>
        <%: Html.ValidationMessageFor(model => model.FightName) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Fighter1ID) %><br />
        <%: Html.LabelFor(model => model.Fighter1Reference.Value.FighterName)%>
    </div>
    <div class="editor-field">
        <%: Html.DropDownList("Fighter1ID", new SelectList(ViewData["Fighters"] as IEnumerable, "ID", "FighterName", Model.Fighter1ID))%>
        <%: Html.ValidationMessageFor(model => model.Fighter1ID) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Fighter2ID) %>
    </div>
    <div class="editor-field">
        <%: Html.DropDownList("Fighter1ID", new SelectList(ViewData["Fighters"] as IEnumerable, "ID", "FighterName", Model.Fighter1ID))%>
        <%: Html.ValidationMessageFor(model => model.Fighter2ID) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Fighter1Login) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.Fighter1Login) %>
        <%: Html.ValidationMessageFor(model => model.Fighter1Login) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Fighter2Login) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.Fighter2Login) %>
        <%: Html.ValidationMessageFor(model => model.Fighter2Login) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.FightStatusID) %>
    </div>
    <div class="editor-field">
        <%: Html.TextBoxFor(model => model.FightStatusID) %>
        <%: Html.ValidationMessageFor(model => model.FightStatusID) %>
    </div>
    <p>
        <input type="submit" value="Save" />
    </p>
</fieldset>
<% } %>

And this is my model for fights:

public class FightDetailsViewModel
{
    public Fight Fight { get; set; }
    public List<Fighter> Fighters { get; set; }
}

There is no ViewModel for fighters (in any case, this is not involved in this scenario).

I can post any code you might want to see.

: ViewModel MVC 2 HTML- ASP.NET MVC 2 UpdateModel() , .

UpdateModel(fighter, "Fighter"); , UpdateModel(fighter);. , Fighter Fighter, , Fight model.Fight, . . : asp.net mvc2 - model.something ?
