Updating user by UserManager.Update() in ASP.NET Identity 2

Question

I use ASP.NET Identity 2 in an MVC 5 project and I want to update Student data by using UserManager.Update() method. However,

Answer 1

This took me a little while to understand, but you simply need to use the UserManager. My task was to simply update the LoginViewModel with a new Date. I tried different methods, but the only thing that seemed to work was FindByEmailAsync, which is specific to my MODEL because I'm not using Id to sign in.

Case SignInStatus.Success
            Dim user As ApplicationUser = Await UserManager.FindByEmailAsync(model.Email)
            user.LastActivityDate = model.LastActivityDate

            UserManager.Update(user)

            Return RedirectToLocal(returnUrl)

Answer 2

There is no need to pass the student as ApplicationUser to the UserManager.Update() method (because Student class inherits (hence is) ApplicationUser).

The problem with your code is that you are using new Student operator, thus creating a new student rather than updating the existing one.

Change the code like this:

// Get the existing student from the db
var user = (Student)UserManager.FindById(model.Id);

// Update it with the values from the view model
user.Name = model.Name;
user.Surname = model.Surname;
user.UserName = model.UserName;
user.Email = model.Email;
user.PhoneNumber = model.PhoneNumber;
user.Number = model.Number; //custom property
user.PasswordHash = checkUser.PasswordHash;

// Apply the changes if any to the db
UserManager.Update(user);
