如何建立两个模型之间的关系并更新数据库

我又来了,但现在我需要你的一些帮助,我有一些版本的购物车,整个想法就是当我点击产品按钮时数据库要用用户信息更新( id)订购产品(id)。首先我使用信息(id,product_name,price)创建订单表,其他表是users表(id,user_name)和最终表user_order表(id,user_id,order_id);

之后我制作了两个模型,一个是产品的订单模型,第二个是用户模型。我想要的关系是这两种模式之间的关系。

用户模型功能:

public function orders(){
        return $this->belongsToMany('App\Orders', 'user_order', 'user_id', 'order_id');
       // return $this->belongsToMany('App\Orders');
    }

订单模型功能:

public function users(){
      return $this->belongsToMany('App\User', 'user_order', 'order_id', 'user_id');
        //return $this->belongsToMany('App\User');
   }

这是我使用提交按钮显示所有产品的主要HTML:

 <div class="row">
                    @foreach($orders as $order)
                    <div class="col-sm-4 col-lg-4 col-md-4">
                        <div class="thumbnail">
                            <img src="http://placehold.it/320x150" alt="">
                            <div class="caption">
                                <h4 class="pull-right">{{ $order->cena }}</h4>
                                <h4><a href="#">{{ $order->order_name }}</a>
                                </h4>

                            </div>
                            <div class="ratings">
                                <p class="pull-right">15 reviews</p>
                                <p>
                                    <span class="glyphicon glyphicon-star"></span>
                                    <span class="glyphicon glyphicon-star"></span>
                                    <span class="glyphicon glyphicon-star"></span>
                                    <span class="glyphicon glyphicon-star"></span>
                                    <span class="glyphicon glyphicon-star"></span>
                                </p>
                            </div>
                            <div class="btn-group center">

                                <a href="{{ route('product.makeOrder',['id' => $order->id]) }}" name="req" class="btn btn-warning">Order this product!</a> 
                            </div> 
                            <br>
                        </div>
                    </div>
                    @endforeach

控制器功能:

public function makeOrder(Request $request, $id){

        $user = User::where('email', $request['email'])->first();
        $findorder = Orders::find($id);
        //$user->orders()->detach();
        $user->orders()->attach(Orders::where('id', $findorder))->first();

        return redirect()->back();

    }

路线:

Route::get('/add-to-database/{id}',[
        'uses' => 'AppController@makeOrder',
        'as' => 'product.makeOrder'
        ]);

整个想法是如何在提交按钮后使用用户的id和产品的id更新表user_order来创建函数。

有任何帮助吗?

答案 0 :(得分:0)

您的makeOrder()应该是:

public function makeOrder(Request $request, $id) {
  $user = User::where('email', $request->get('email'))->first();

  // this is to make sure that order is available in database
  $order = Orders::findOrFail($id);

  $user->orders()->attach($order->id);

  return redirect()->back();
}
