Laravel 5:如何使用Eloquent对数据透视表进行连接查询？

Question

我的Laravel应用程序中有2个表,即客户和商店.客户可以属于许多商店,商店可以拥有许多客户.它们之间有一个数据透视表来存储这种关系.

问题是,如何使用Eloquent提取给定商店的客户列表？可能吗？我目前能够使用Laravel的Query Builder提取它.这是我的代码:

| customers | stores      | customer_store |
-------------------------------------------
| id        | id          | customer_id    |
| name      | name        | store_id       |
| created_at| created_at  | created_at     |
| updated_at| updated_at  | updated_at     |

客户模型:

public function stores(){
        return $this->belongsToMany(Store::class)
            ->withPivot('customer_store', 'store_id')
            ->withTimestamps();
    }

商店型号:

public function customers(){
        return $this->belongsToMany(Customer::class)
            ->withPivot('customer_store', 'customer_id')
            ->withTimestamps();
    }

数据库查询(使用查询生成器):

$customer = DB::select(SELECT customers.id, customers.name, customers.phone, customers.email, customers.location FROM customers LEFT JOIN customer_store on customers.id = customer_store.customer_id WHERE customer_store.store_id = $storeID);

Answer 1

试试这个:

public function result(Request $request) {

    $storeId = $request->get('storeId');

    $customers = Customer::whereHas('stores', function($query) use($storeId) {
        $query->where('stores.id', $storeId);
    })->get();

}
