MVC5 ApplicationUser custom properties

问题:

I am trying to get to grips with the new Membership system introduced in ASP.NET MVC 5 and I've come across a small issue which I am pretty sure you will be able to help me with.

I am going based off this tutorial and have introduced custom properties to ApplicationUser such as Name, Surname, DOB, etc.

However, instead of creating the user, I am trying to update the currently logged in one. I am looking at the controller method which is currently used to change password.

public async Task<ActionResult> Manage(ManageUserViewModel model)
        {
            string userId = User.Identity.GetUserId();
            bool hasLocalLogin = await IdentityManager.Logins.HasLocalLoginAsync(userId);
            ViewBag.HasLocalPassword = hasLocalLogin;
            ViewBag.ReturnUrl = Url.Action("Manage");

            if (hasLocalLogin)
            {               
                if (ModelState.IsValid)
                {
                    IdentityResult result = await IdentityManager.Passwords.ChangePasswordAsync(User.Identity.GetUserName(), model.OldPassword, model.NewPassword);
                    if (result.Success)
                    {
                        return RedirectToAction("Manage", new { Message = "Your password has been changed." });
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }
            }
            else
            {
                // User does not have a local password so remove any validation errors caused by a missing OldPassword field
                ModelState state = ModelState["OldPassword"];
                if (state != null)
                {
                    state.Errors.Clear();
                }

                if (ModelState.IsValid)
                {
                    // Create the local login info and link it to the user
                    IdentityResult result = await IdentityManager.Logins.AddLocalLoginAsync(userId, User.Identity.GetUserName(), model.NewPassword);
                    if (result.Success)
                    {
                        return RedirectToAction("Manage", new { Message = "Your password has been set." });
                    }
                    else
                    {
                        AddErrors(result);
                    }

            }
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

How exactly would I go on about updating an ApplicationUser's Surname for example? Do I need to call the DbContext or?

I hope my question is clear.

回答1:

Explore IdentityManager.Store.UserManagement and IdentityManager.Store.Users.

ApplicationUser cUser = (ApplicationUser) await IdentityManager.Store.Users.FindByNameAsync(HttpContext.User.Identity.Name, new System.Threading.CancellationToken());
cUser.Surname = "New Something";
IdentityResult result1 = await IdentityManager.Store.SaveChangesAsync();

Above code is an example only. Basically you need to explore the Store property of IdentityManage.

When we used the Users object of our database context we ran into other tracking errors. In our application, we would retrieve users as such

var user = UserManager.FindById(userId);

Edit the properties:

user.StorageName = "gooblygook";
//whatever other properties you would like to use

And then we would save it with the UserManager in the controller:

UserManager.Update(user);

This is currently a working solution for us.

Mark the Person object as virtual in your ApplicationUser definition. That worked for me.

public class ApplicationUser : IdentityUser
{
    public virtual Person Person { get; set; }
