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

When going the other way (hasMany):

User::with(array('post'=>function($query){
    $query->select('id','user_id');
}))->get();

Don't forget to include the foreign key (assuming it is user_id in this example) to resolve the relationship, otherwise you'll get zero results for your relation.
