我在MVC项目上实现ASPNetIdentity时遇到了麻烦 我在var行中收到此错误(实体类型IdentityRole不是当前上下文模型的一部分。):
using System;
using System.Linq;
using System.Web.Mvc;
using EZ.Models;
using Microsoft.AspNet.Identity.EntityFramework;
namespace EZ.Controllers
{
public class RoleController : Controller
{
ApplicationDbContext context;
public RoleController()
{
context = new ApplicationDbContext();
}
/// <summary>
/// Get All Roles
/// </summary>
/// <returns></returns>
public ActionResult Index()
{
var roles = context.Roles.ToList();
return View(roles);
}
/// <summary>
/// Create a New role
/// </summary>
/// <returns></returns>
// GET: /Roles/Create
public ActionResult Create()
{
return View();
}
//
// POST: /Roles/Create
[HttpPost]
public ActionResult Create(FormCollection collection)
{
try
{
context.Roles.Add(new Microsoft.AspNet.Identity.EntityFramework.IdentityRole()
{
Name = collection["RoleName"]
});
context.SaveChanges();
ViewBag.ResultMessage = "Role created successfully !";
return RedirectToAction("Index");
}
catch
{
return View();
}
}
/// <summary>
/// Set Role for Users
/// </summary>
/// <returns></returns>
public ActionResult SetRoleToUser()
{
var list = context.Roles.OrderBy(role => role.Name).ToList().Select(role => new SelectListItem { Value = role.Name.ToString(), Text = role.Name }).ToList();
ViewBag.Roles = list;
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult UserAddToRole(string uname, string rolename)
{
ApplicationUser user = context.Users.Where(usr => usr.UserName.Equals(uname, StringComparison.CurrentCultureIgnoreCase)).FirstOrDefault();
// Display All Roles in DropDown
var list = context.Roles.OrderBy(role => role.Name).ToList().Select(role => new SelectListItem { Value = role.Name.ToString(), Text = role.Name }).ToList();
ViewBag.Roles = list;
if (user != null)
{
var account = new AccountController();
account.UserManager.AddToRoleAsync(user.Id, rolename);
ViewBag.ResultMessage = "Role created successfully !";
return View("SetRoleToUser");
}
else
{
ViewBag.ErrorMessage = "Sorry user is not available";
return View("SetRoleToUser");
}
}
}
}
我已经在我的数据库中编写了表格。
这与CodeProject.com中的role-security-mvc5-master项目完全相同。唯一的区别是我在我的数据库中移动了表,并且更改了连接字符串。我错过的是什么?
在我的IdentityModel.cs中我有:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
如果您需要更多代码,请告诉我,我会发布。
