Laravel 5 eloquent包含来自第二个连接表的外键的另一个表的行

Question

我有3个样本模型

1. 顾客 ID
2. 订购 ID 顾客ID deliver_address_id
3. customer_address id customer_id 街 国家

客户可以在他的个人资料中保存许多地址，但他每个订单只能选择一个地址。

我想在一个查询中使用laravel 5 eloquent获取所有客户订单，包括地址。我是laravel的新手，因此难以查询复杂的关系表。

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');
    }

}
