Update user profile in MVC 5

Hi, I am using identitiy framework to my existing application (I added it after I start working with the login).

Generally, I was using my own database. Right Now, I have the user inserted in 2 tables 1- my own table 2- aspnetUsers table.

As a resule, when I try to update or display user profile I use the identity user to generate that information.

However, when the user login and try to access the profile view, I'm getting an error that the "UserName" parameter cann't be null.

How Would I generate the user information in this case?

My action function looks as the following:

[HttpGet]
public async Task UpdateDriverProfile()
{
var user = User.Identity.Name;
var userStore = new UserStore();
var userManager = new UserManager(new UserStore(new RidesDbContext()));
DriversModel driver = new DriversModel();
IdentityUser theUser = new IdentityUser()
{
UserName = driver.email,
Email = driver.email
};
driver.email = theUser.UserName;
driver.email = theUser.Email;
driver.phoneNumber = theUser.PhoneNumber;
driver.PasswordHash = theUser.PasswordHash;
driver.userID = theUser.Id;
var store = await userStore.FindByNameAsync(theUser.UserName);
theUser = await userManager.FindByNameAsync(driver.email);
DriversTier tier = new DriversTier();
driver = tier.getDriverByUserID(driver.userID);
return View("UpdateDriverProfile", driver);
}

just to make things clear, this is how I rwgister or add the user to the database:

[HttpPost]
public async Task DriversRegistration(DriversModel driver, IEnumerable images)
{
var profileImg = images.ElementAt(0);
var licenseImg = images.ElementAt(1);
//First check the first Image
if (profileImg != null && profileImg.ContentLength > 0)
{
driver.profileImgType = profileImg.ContentType;
string fileName = profileImg.FileName;
string pattern = @"([^\s]+(\.(?i)(jpg|png|gif|bmp))$)";
Regex rgx = new Regex(pattern);
//Get the length of the image in bytes and create that array
driver.profileImg = new byte[profileImg.ContentLength];
//fill the array of bytes with the image data
profileImg.InputStream.Read(driver.profileImg, 0, profileImg.ContentLength);
//Need to do model state checking here, provided some code for that already
ModelState.Clear();
}
//Now check the second Image
if (licenseImg != null && licenseImg.ContentLength > 0)
{
driver.licenseImgType = licenseImg.ContentType;
string fileName = licenseImg.FileName;
string pattern = @"([^\s]+(\.(?i)(jpg|png|gif|bmp))$)";
Regex rgx = new Regex(pattern);
//Get the length of the image in bytes and create that array
driver.licenseImg = new byte[licenseImg.ContentLength];
//fill the array of bytes with the image data
licenseImg.InputStream.Read(driver.licenseImg, 0, licenseImg.ContentLength);
//Need to do model state checking here, provided some code for that already
ModelState.Clear();
}
if (ModelState.IsValid)
{
bool processError = false;
var userStore = new UserStore();
var userManager = new UserManager(userStore);
string statusMessage = "";
IdentityUser theUser = new IdentityUser() {
UserName = driver.email,
Email = driver.email,
PasswordHash = driver.PasswordHash,
PhoneNumber = driver.phoneNumber
};
IdentityResult theResult = await userManager.CreateAsync(theUser,driver.PasswordHash);
var store = await userStore.FindByNameAsync(theUser.UserName);
theUser = await userManager.FindByNameAsync(driver.email);
string UserName = theUser.UserName;
string password = theUser.PasswordHash;
string Email = theUser.Email;
string phoneNumber = theUser.PhoneNumber;
string userID = theUser.Id;
driver.userID = userID;
DriversTier tier = new DriversTier();
int newID = tier.insertDriver(driver);
driver.driverId = newID;
if (theResult == IdentityResult.Success)
{
//First check to see if User Role exists. If not create it and add user to User role.
if (driver != null)
{
var roleStore = new RoleStore();
var roleManager = new RoleManager(roleStore);
var therole = new IdentityRole("Driver");
theResult = await roleManager.CreateAsync(therole);
if (theResult == null)
{
statusMessage = string.Format("User Group Creation failed because : {0}", theResult.Errors.FirstOrDefault());
//Need to exit nicely here for some reason, we could not create the role with the DB
processError = true;
}
}
if (!processError)
{
//The role exists, now add the user to the role
theResult = await userManager.AddToRoleAsync(theUser.Id, "Driver");
statusMessage = string.Format("Identity User {0} was created successfully! {0} was added to the User group: {1}", theUser.UserName, theResult.Errors.FirstOrDefault());
}
}
else
{
//could not create a user
statusMessage = string.Format("User Creation failed because : {0}", theResult.Errors.FirstOrDefault());
processError = true;
}
List userList = userManager.Users.ToList();
return RedirectToAction("ThankYou", "Default");
}
else
{
return View();
}

and this is the model I'm using for both registration and the profile:

public class DriversModel
{
[Key]
[Display(Name ="Id")]
public int driverId { get; set; }
//this is the FK associated with the aspnetusers table
public string userID { get; set; }
[Display(Name = "First Name")]
[Required(ErrorMessage = "Pleas Enter Your First Name")]
public string firstName { get; set; }
[Display(Name = "Last Name")]
[Required(ErrorMessage = "Pleas Enter Your Last Name")]
public string lastName { get; set; }
[Display(Name = "Email Address")]
[DataType(DataType.EmailAddress)]
[Required(ErrorMessage = "Pleas Enter Your Email Address")]
[RegularExpression(".+\\@.+\\..+", ErrorMessage = "Please Enater a Valid Email Address")]
public string email { get; set; }
[Display(Name = "Mobile Number")]
[Required(ErrorMessage = "Pleas Enter Your Mobile Number")]
public string phoneNumber { get; set; }
[Display(Name = "Address")]
[Required(ErrorMessage = "Pleas Enter Your Address")]
public string Address { get; set; }
[Display(Name = "City")]
[Required(ErrorMessage = "Pleas Enter Your City")]
public string city { get; set; }
[Display(Name = "State")]
[Required(ErrorMessage = "Pleas Enter Your state")]
public string state { get; set; }
[Display(Name = "Car")]
[Required(ErrorMessage = "Please Identify Your Car")]
public string car { get; set; }
[Display(Name = "Driver's License")]
[Required(ErrorMessage = "Please Enter Your Driver's Licende Number")]
public string driverslicense { get; set; }
[Display(Name ="Profile Image")]
[Required]
public byte[] profileImg { get; set; }
public string profileImgType { get; set; }
[Display(Name = "License Image")]
[Required]
public byte[] licenseImg { get; set; }
public string licenseImgType { get; set; }
[Display(Name ="Password")]
[DataType(DataType.Password)]
[Required(ErrorMessage ="Please Enter a password")]
public string PasswordHash { get; set; }
[Display(Name = "Username")]
public string UserName { get; set; }
}
}

I would appreciate your help. Thank You.

It is null, How would I get the username there?
Can you please demonstrate that?

Thank you

you are getting error because your username is null here,
IdentityUser theUser = new IdentityUser()

           {
             UserName = driver.email,
             Email = driver.email
           };
you need to get username here first and then get user data and assing correct in above place then it will work for you.

I am getting the store = null //line#15

I don't know how to insert an image in this editor.

I have changed code snippet on previous answer. Could you please check and let me know? If you face the issue.

The registration works as expected, but the updateProfile Action doesn't.
I don't have any problem with the registration part. I just add it for clarefication of what I am doing.

Thank You.

Hi,

Put debugger in below code and check you are getting data here, You UserName not getting values. In below code line no - 5 your are assigning driver email. Check there you are getting data. Line no 15 you are using theUser.UserName in parameter. using FindByNameAsync(theUser.UserName)
DriversModel driver = new DriversModel();
           IdentityUser theUser = new IdentityUser()

           {
             UserName = driver.email,
             Email = driver.email
           };

           driver.email = theUser.UserName;
           driver.email = theUser.Email;
           driver.phoneNumber = theUser.PhoneNumber;
           driver.PasswordHash = theUser.PasswordHash;
           driver.userID = theUser.Id;

           var store = await userStore.FindByNameAsync(theUser.UserName);
           theUser = await userManager.FindByNameAsync(driver.email);
