为 ApplicationUser.cs 添加控制器？ MVC 核心

Question

我正在尝试为 ApplicationUser.cs 添加一个控制器，以便当管理员登录时，他们能够查看、编辑、删除 dbo.AspNetUsers 表中的任何记录，但是我认为我正在这样做它错了。有什么想法吗？

这是 ApplicationUser.cs 的代码：

namespace ProjectTest.Models
{
    // Add profile data for application users by adding properties to the ApplicationUser class
    public class ApplicationUser : IdentityUser
    {
        public string Summary { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        override public string UserName { get; set; }
        public string RoleType { get; set; }
        public string Address { get; set; }
        public string City { get; set; }
        override public string PhoneNumber { get; set; }
        override public string Email { get; set; }
    }
}

当我尝试为 ApplicationUser 模型类添加控制器时，控制器被创建（包括视图文件）但无法启动。控制器是新建控制器后的默认代码。

你完全走上了正轨，Dean。 但是，我将向您介绍如何手动创建控制器，以及如何创建编辑方法。随意检查您生成的控制器是否有任何不匹配，或者更好的是，完全按照这些步骤操作。

首先：我建议您创建一个仅包含您打算向管理员公开的属性的 Viewmodel（在一个新文件中）。此视图模型可能如下所示。

public class UserViewModel
{    
    public string Summary { get; set; }
    public string Email { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string RoleType { get; set; }
    public string Address { get; set; }
    public string City { get; set; }
    override public string PhoneNumber { get; set; }
}

请注意，使用视图模型是一种更标准化的方法，因此请随意跳过此步骤。

下一步：您应该创建一个控制器，例如 AdminControllerlike so。

[Authorize(Roles = "Admin")]
public class AdminController : Controller
{
     private readonly ApplicationDbContext _dataContext;
     private readonly UserManager<ApplicationUser> _userManager;

    public AdminController(ApplicationDbContext dataContext, UserManager<ApplicationUser> userManager, IHostingEnvironment environment)
    {
        // Inject the datacontext and userManager Dependencies
        _dataContext = dataContext;
        _userManager = userManager;
    }

    // HTTPGET Controller action to edit user
    [HttpGet]
    public IActionResult EditUser()
    {
        return View();
    }

     // HTTPPOST Controller action to edit user
    [HttpPost]
    public async Task<IActionResult> EditUser(UserViewModel model)
    {
        //Get User by the Email passed in.
        /*It's better practice to find user by the Id, (without exposing the id to the view).
        However, to keep this example simple, we can find the user by email instead*/
        var user = await _userManager.FindByEmailAsync(model.Email);

        //edit user: replace values of UserViewModel properties 
        user.Summary = model.Summary;
        user.FirstName = model.FirstName;
        user.LastName = model.LastName;
        user.RoleType = model.RoleType;
        user.Address = model.Address;
        user.City = model.City;

         //add user to the datacontext (database) and save changes
        _dataContext.Update(user);
        await _dataContext.SaveChangesAsync();

        return RedirectToAction("ACTION_NAME", "CONTROLLER_NAME");
        //this could be
        //return RedirectToAction("Index", "Home");
    }
}
