Get Specific Columns Using “With()” Function in Laravel Eloquent

Question

I have two tables, User and Post. One User can have many posts and one post belongs to only one user

Answer 1

Try with conditions.

$id = 1;
Post::with(array('user'=>function($query) use ($id){
    $query->where('id','=',$id);
    $query->select('id','username');
}))->get();
