How do I store user input into database using ASP.NET Core MVC? - asp.net-mvc

Question

I am struggling to find a solution on how to add user input like first name, last name, zipcode.... to the database. The email is already stored in database during signUp.
I tried looking at some resource but they seem complicated.
HomeController
public async Task<IActionResult> ProfileView(ApplicationUser users)
{
return View();
}
Application user model:
public class ApplicationUser: IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public int ZipCode { get; set; }
}
Profile view:
<form>
<div class="form-row">
<div class="form-row col-md-6">
<div class="col">
<label for="firstName">First Name:</label>
<input type="text" class="form-control" placeholder="First name">
</div>
<div class="col col-md-6">
<label for="lastName">Last Name:</label>
<input type="text" class="form-control" placeholder="Last name">
</div>
</div>
<div class="form-group col-md-6">
<label for="inputEmail4">Email</label>
<input type="email" class="form-control" id="inputEmail4" placeholder="Email">
</div>
</div>
Database context:
public class DataBaseContext: IdentityDbContext<ApplicationUser>
{
public DataBaseContext(DbContextOptions<DataBaseContext> options): base(options)
{
}
public new DbSet<SignUp> Users { get; set; }
public DbSet<Products> Products { get; set; }
}
When the user fills out the information in the view it should store it in an existing database.

Here is a working example on modifying user's profile after logining :
Profile View :
#model MVC2_2Project.Models.ApplicationUser
<div class="row">
<div class="col-md-6">
<form id="profile-form" method="post">
<div asp-validation-summary="All" class="text-danger"></div>
<div class="form-group">
<label asp-for="FirstName"></label>
<input asp-for="FirstName" class="form-control" placeholder="First name"/>
<span asp-validation-for="LastName" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="LastName"></label>
<input asp-for="LastName" class="form-control" placeholder="Last name"/>
<span asp-validation-for="LastName" class="text-danger"></span>
</div>
<button id="update-profile-button" type="submit" class="btn btn-primary">Save</button>
</form>
</div>
</div>
#section Scripts {
<partial name="_ValidationScriptsPartial" />
}
HomeController:
public class HomeController : Controller
{
private readonly UserManager<ApplicationUser> _userManager;
private readonly SignInManager<ApplicationUser> _signInManager;
private readonly ApplicationDbContext _context;
public HomeController(
UserManager<ApplicationUser> userManager,
SignInManager<ApplicationUser> signInManager,
ApplicationDbContext context)
{
_userManager = userManager;
_signInManager = signInManager;
_context = context;
}
public async Task<IActionResult> ProfileView()
{
var user = await _userManager.GetUserAsync(User);
if (user == null)
{
return NotFound($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
}
return View(user);
}
[HttpPost]
public async Task<IActionResult> ProfileView(ApplicationUser users)
{
if (!ModelState.IsValid)
{
return View();
}
var user = await _userManager.GetUserAsync(User);
if (user == null)
{
return NotFound($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
}
user.FirstName = users.FirstName;
user.LastName = users.LastName;
_context.Users.Update(user);
await _context.SaveChangesAsync();
await _signInManager.RefreshSignInAsync(user);
return RedirectToAction();
}
}
