Laravel 5雄辯inlcude從第2的外鍵的其它表的行加入表

Question

我有3個樣本模型

1. 客戶

   ID

2. 爲了

   id

   CUSTOMER_ID

   deliver_address_id

3. customer_address

   ID CUSTOMER_ID

   街道

   國家

客戶可以在其個人資料中保存許多地址，但他只能爲每個訂單選擇一個地址。

我想獲得所有的客戶訂單，包括一個查詢中的地址，使用laravel 5 eloquent。我是laravel的新手，所以很難查詢複雜的關係表。我希望有人可以幫助我..謝謝

Answer 1

class Customer extends Model { 

    $table = 'customers'; 

    function addresses(){ 
     return $this->hasMany(Address::class, 'customer_id'); 
    } 

    function orders(){ 
     return $this->hasMany(Order::class, 'customer_id'); 
    } 

} 

class Order extends Model { 

    $table = 'orders'; 

    function address(){ 
     return $this->belongsTo(Address::class, 'address_id'); 
    } 

    function customer() { 
     return $this->belongsTo(Customer::class, 'customer_id'); 
    } 
} 

class Address extends Model{ 

    $table = 'customer_addresses'; 

    function customer(){ 
     return $this->belongsTo(Customer::class, 'customer_id'); 
    } 

}
