I am trying to do a project using the MVC entity framework code first method. I have been following the Microsoft tutorial but with different data to get this far (http://www.asp.net/mvc/overview/getting-started/getting-started-with-ef-using-mvc/creating-an-entity-framework-data-model-for-an-asp-net-mvc-application). I have a person model:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace CleryAct.Models
{
public class Person
{
[Key]
public string rockets { get; set; }
public bool csa { get; set; }
public string fname { get; set; }
public string lname { get; set; }
public string email { get; set; }
public virtual ICollection<Session> Sessions { get; set; }
}
}
And I have a sessions model
using System;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
namespace CleryAct.Models
{
public class Session
{
[Key]
public int ID { get; set; }
public string rockets { get; set; }
public virtual Person Person { get; set; }
public DateTime training { get; set; }
}
}
I then created a new scaffolding item under controller for both person and session. I have not done anything to the code auto generated to the view or the controller.cs files. Up to this point it works fine unless I power down my computer. If I turn off my computer the view ends up with errors all over. Deleting both the view and the controller and reading them fixes the problem until I restart my computer and the errors come back. This is an issue because I cannot keep deleting the files and re-adding them. This is my auto generated view code
@model IEnumerable<CleryAct.Models.Session>
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
<th>
@Html.DisplayNameFor(model => model.Person.fname)
</th>
<th>
@Html.DisplayNameFor(model => model.training)
</th>
<th></th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.DisplayFor(modelItem => item.Person.fname)
</td>
<td>
@Html.DisplayFor(modelItem => item.training)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=item.ID }) |
@Html.ActionLink("Details", "Details", new { id=item.ID }) |
@Html.ActionLink("Delete", "Delete", new { id=item.ID })
</td>
</tr>
}
</table>
Model and Viwebag have an error saying ____ does not exist in current context. Actionlink and DisplayNameFor have the error message 'System.web.webpages.html.htmlhelper' does not contain a definition for ________ and no extention method __________ accepting the first argument type 'system.web.webpages.html.htmlhelper' could be found (are you missing a user directive or an assembly reference). Updating the database does not fix it. A clean and rebuild does not fix it. Starting over with a new database does not fix it (or at least I think I did that right). The only thing that works is completely deleting it and re-adding it. Which only works until the next time I restart my computer. Every autogenerated view has these errors that behave in the same way. Any ideas? web.config
