【问题描述】:
由于某种原因,我无法链接模型对象。我正在尝试为“订单”加载“位置”,并且希望将逻辑包含在模型本身中。但是过了一个链就不行了。
class Order extends Eloquent {
protected $table = 'orders';
public function customer() {
return $this->belongsTo('Customer');
public function location() {
return $this->customer()->location(); // this does not work
}
}
class Customer extends Eloquent {
protected $table = 'customers';
public function user() {
return $this->belongsTo('User');
}
public function orders() {
return $this->hasMany('Order');
}
public function location() {
return $this->user()->location();
// return $this->user(); // WORKS!!
}
}
class User extends Eloquent {
protected $table = 'users';
public function locations() {
return $this->hasMany('Location');
}
public function location() {
return $this->locations()->first();
}
}
我最终想这样做:
class ChefController extends BaseController {
public function get_orders() {
$chef = $this->get_user_chef(); // this already works
return $chef->orders()->with('location')->get(); // does not work
}
}
