Laravel - get values of relation to the same model - php

Question

I have my User Table, which has a ID and a comes_from (id), which points to the id column of the same user table.
for example:
User
id, comes_from
1, null
2, 1
So user with ID 2 comes from user with ID 1
Now I'm trying to build this.
I want to print out a table with all users I have and another table column which gives me the email of the user, that the current row user comes from.
My User model:
public function recruited()
{
return self::findOrFail($this->comes_from)->pluck('email', 'id');
}
Now in my Controller:
public function recruitedUsersList()
{
return view('admin.recruitedUsers')->with('users', User::all()->with('recruited'));
}
This tells me "Call to undefined method with"
In my blade:
#foreach($users as $user)
<tr>
<td>{{ $user->id }}</td>
<td>{{ $user->email }}</td>
<td>{{ $user->name }}</td>
<td>{{ $user->recruited()->email }}</td>
</tr>
#endforeach
Well.. this doesn't work for me. Does someone has a idea?
The Idea is:
A user can come from only one person. He get the "comes_from (id) as he register himself"
A User can recruite as many people as he wants.

Answer 1

Note: I assume a person can recruit more than one other person in your application. So I think hasMany relationship best describes this.
Update the function in your User Model
public function recruited()
{
return $this->hasMany('App\User', 'comes_from');
}
Update your controller to this
public function recruitedUsersList()
{
return view('admin.recruitedUsers')->with('users', User::with('recruited')->get());
}
Update your view logic to this
#foreach($users as $user)
<tr>
<td>{{ $user->id }}</td>
<td>{{ $user->email }}</td>
<td>{{ $user->name }}</td>
<td>
#foreach($user->recruited as $recruit)
{{ $recruit->email }},
#endforeach
</td>
</tr>
#endforeach
