php - Laravel Eager Loading - Load only specific columns

Question

I am trying to eager load a model in laravel but only return certain columns. I do not want the whole eager loaded table being presented.

public function car()
{
    return $this->hasOne('Car', 'id')->get(['emailid','name']);
}

I am getting the following error:

log.ERROR: exception 'SymfonyComponentDebugExceptionFatalErrorException' with message 'Call to undefined method IlluminateDatabaseEloquentCollection::getAndResetWheres()'

Answer 1

Make use of the select() method:

public function car() {
    return $this->hasOne('Car', 'id')->select(['owner_id', 'emailid', 'name']);
}

Note: Remember to add the columns assigned to the foreign key matching both tables. For instance, in my example, I assumed a Owner has a Car, meaning that the columns assigned to the foreign key would be something like owners.id = cars.owner_id, so I had to add owner_id to the list of selected columns;
