php - Laravel 4 Eager Loading in Many to Many Relationship

Question

Trying to do a simple eager load with Laravel 4 using a many to many relationships. My Models look like.

class Facility extends Eloquent {

    public function photos(){
            return $this->belongsToMany('Photo');
    }
}

class Photo extends Eloquent {

    public function facilities(){
            return $this->belongsToMany('Facility');
    }
}

Tabes are set up according to Laravel standards. When I try to load using

$facilities = Facility::with('Photo')->get();

I end up with a Laravel error

Call to undefined method Illuminate\Database\Query\Builder::photo()

Any idea whats being done wrong here?

Answer 1

你应该试试：

$facilities = Facility::with('photos')->get();

请记住，您传递给的参数with()是方法，而不是模型，因此如果您在模型中有另一个方法，例如：location()，您将调用：

$facilities = Facility::with(['photos', 'location'])->get();
