laravel 5 - 机锋关系的两个表

Question

我在Laravel是新的，我有2类模型（表客户和订单）：

table Customer, with columns: 
    - id_cust (PK) 
    - name 

table Order, with columns: 
    - id_order (PK) 
    - id_cust (FK to table Customer) 
    - product_name 
    - qty 

我尝试做模型 “客户”：

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Customer extends Model 
{ 
    protected $primaryKey = 'id_cust'; 
    protected $table = 'customer'; 
} 

和模型类 '订单'：

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Order extends Model 
{ 
    protected $primaryKey = 'id_order'; 
    protected $table = 'order'; 
} 

在SQL：

select a.id_cust, a.name, b.product, b.qty 
    from customer a, order b 
where a.id_cust = b.id_cust; 

我想这样的输出：

======================================== 
|id_cust |name |product |qty | 
|======================================| 
|10  |jeff |Plastic |10  | 
|10  |jeff |Book  |2  | 
|11  |james |Laptop  |1  | 
|11  |james |TV   |1  | 
|12  |davy |shoe  |1  | 
======================================== 

我尝试在控制器，但没有成功

<?php 
namespace App\Http\Controllers; 

use Illuminate\Http\Request; 
use App\Http\Requests; 
use App\Http\Controllers\Controller; 

use App\customer; 
use App\order; 

class ShowDetail extends Controller 
{ 

    public function index(){ 

    $aa = customer->where('customer.id_cust','=','order.id_cust')->order-get(); 
    var_dump($aa); 
    } 
} 

什么建议吗？

谢谢。

顺序模型

Answer 1

：

public function customer(){ 
    return $this->belongsTo('App\Customer'); 
} 

客户模式：

public function order(){ 
    return $this->hasMany('App\Order'); 
} 

，然后在控制器：

public function index(){ 
    $aa= Customer::with('orders')->get(); 
    var_dump($aa); 
}
