Display UserName and Role in MVC4 - asp.net-mvc

Question

I want to create an easy Admin panel for editing users roles. First I want to display users list with their roles.
First I edited some things in AccountModel:
Context:
public class UsersContext : DbContext
{
public UsersContext()
: base("DefaultConnection")
{
}
public DbSet<UserProfile> UserProfiles { get; set; }
public DbSet<UserRole> UserRole { get; set; }
}
User profile:
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public string EmailId { get; set; }
public string Details { get; set; }
public virtual ICollection<UserRole> UserRole { get; set; }
}
User roles:
[Table("webpages_Roles")]
public class UserRole
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int RoleId { get; set; }
public string RoleName { get; set; }
public virtual ICollection<UserProfile> UserProfile { get; set; }
}
After that I created UserController with ActionResult Index:
public ActionResult Index()
{
using (var db = new UsersContext())
{
return View(db.UserProfiles.Include("UserRole").ToList());
}
}
And View:
#model IEnumerable<AnimeWeb.Models.UserProfile>
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
#Html.ActionLink("Create New", "Create")
</p>
<table>
<tr>
<th>
User Name
</th>
<th>
User Role
</th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.UserName)
</td>
<td>
#Html.DisplayFor(modelItem => item.UserRole)
</td>
</tr>
}
Partial View for UserRole looks like this:
#model AnimeWeb.Models.UserRole
<tr>
#Html.DisplayFor(model => model.RoleName),
</tr>
When I try to execute it I get InnerException error: "Invalid object name 'dbo.UserRoleUserProfiles'.". I dont quite get it. Could someone explain me why is this happening and how to resolve this?

Answer 1

Seems like the problem lies here
public virtual ICollection<UserRole> UserRole { get; set; }
And you don't have a mapping for these classes, so the default setting creates a UserRoleUserProfiles table(or class) and it doesn't exist in the database, so the problem occurs.
You can try remove this line of code and then try run the project again
