Identity User FK - asp.net-core-mvc

Question

I've an application in Asp.NET Core 3.1 MVC with EF Core and Identity.
I've two tables Calls and AspNetUsers. AspNetUsers has many Calls and one Call has one AspNetUsers.
The Calls table structure is okay, I think. But now I need to get Calls from AspNetUsers.
In CallsController I'm trying: IList<Call> calls = this.User.Calls; but no success.
I tried:
IList<Call> calls = this._context.Calls.Where(x => x.UserId == this._userManager.GetUserId(this.User)).ToList();
I've success. But do it is correct?
So, in application i've identity classes and an ApplicationUser like this:
public class ApplicationUser : IdentityUser
{
public virtual IList<Call> Calls { get; set; }
}
And in Startup class in ConfigureServices method:
services.AddDefaultIdentity<ApplicationUser>(options =>
options.SignIn.RequireConfirmedAccount = true)
.AddEntityFrameworkStores<ApplicationDbContext>();
So, What's the better way to get Calls from AspNetUsers? Thanks!

Answer 1

You can set ApplicationUser like :
public class ApplicationUser : IdentityUser
{
public virtual ICollection<Call> Calls { get; set; }
}
Call.cs:
public class Call
{
public int ID { get; set; }
public string name { get; set; }
// other properties
public string UserID { get; set; }
[ForeignKey("UserID")]
public virtual ApplicationUser ApplicationUser { get; set; }
}
In ApplicationDbContext , add :
public virtual DbSet<Call> Calls { get; set; } //add this line
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
Then you can query the current user's call by :
if (User.Identity.IsAuthenticated)
{
var userID = User.Claims.FirstOrDefault(x => x.Type == ClaimTypes.NameIdentifier).Value;
var calls = _applicationDbContext.Users.Include(u => u.Calls).First(u => u.Id == userID).Calls.ToList();
//or
var callsa = _applicationDbContext.Calls.Where(p => p.UserID == userID).ToList();
}

ApplicationUser should be
public class ApplicationUser : IdentityUser
{
public virtual ICollection<Call> Calls { get; set; }
}
Call entity should be
public class Call
{
public int ID { get; set; }
//...
public string ApplicationUserId { get; set; }
[ForeignKey(nameof(ApplicationUserId))]
public virtual ApplicationUser ApplicationUser { get; set; }
}
and, of course, you should override the OnModeCreating method in your DbContext like this
public class ApplicationDbContext: DbContext
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options){}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<Call>()
.HasOne(x => x.ApplicationUser)
.WithMany(x => x.Calls);
}
//...DbSets..
}
and finally, load all your calls in Calls collection of ApplicationUser
var user = await _context.ApplicationUsers.FindAsync(_userManager.GetUserId(this.User));
await context.Entry(user)
.Collection(x => x.Calls)
.LoadAsync();
Now, you have all your calls loaded in Calls collection of the current user.
