ASP.NETCore - Friends System - mysql

Question

I`m building an application where I try to make a friend system.
Now, I work with 2 tables for that.
1st: Default AspNetUsers where i store user information.
2nd: Friends Table as below:
public class AspNetFriends
{
public int ID { get; set; }
public string friendFrom { get; set; }
public string friendTo { get; set; }
public bool isConfirmed { get; set; }
}
In this table both "friendFrom" and "friendTo" is string type, and receiving the registered users ID.
What i want to achieve is that when i display this table on my view, i want to show the Username of the same UserID thats either in the "friendFrom" or "friendTo" column.

Answer 1

You need to change your class as followed (I didn't test this):
Default application user of asp.net core
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
namespace project.Models
{
// Add profile data for application users by adding properties to the ApplicationUser class
public class ApplicationUser : IdentityUser
{
}
}
Model
public class AspNetFriends
{
public int ID { get; set; }
public bool isConfirmed { get; set; }
public virtual ApplicationUser friendFrom { get; set; }
public virtual ApplicationUser friendTo { get; set; }
}
Now you can get to the getters and setters of the aspnet user
Controller
public async Task<IActionResult> Details(int id)
{
var query = from m in _dbContext.AspNetFriends
join ff in _dbContext.Users on
new { m.friendFrom.Id } equals new { Id = cu.Id }
join ft in _dbContext.Users on
new { m.friendTo.Id } equals new { Id = cu.Id }
where m.ID == id
select m;
return View(query.Single());
}
View
#model project.AspNetFriends
<p>
#model.friendFrom.UserName
</P>
#item.CreationUser.UserName
