我有三个表:“用户”,“门票”和“事件”。我想获取用户的票证,而票证的详细信息正在发生。我想使用关系从所有表中获取数据。

我需要用户和用户票证以及该票证的事件

我也做得正确吗?

我已经与所有桌子建立了联系。

表结构为:

用户

-用户名,用户名

机票订单

-user_id,ticket_id,event_id

事件

-event_id,event_name

  

对于用户

    public function ticketOrder(){
        return $this->hasMany('App\TicketOrder', 'user_id', 'user_id');
    }
  

对于门票

public function user(){
       return $this->belongsTo('App\User', 'user_id', 'user_id');
   }

   public function events(){
       return $this->belongsTo('App\Event', 'event_id', 'event_id');
   }
  

事件

 public function ticketOrder(){
        return $this->hasMany('App\TicketOrder', 'event_id', 'event_id');
    }
  

我在控制器中尝试过

     

此处CreateEvent和Event是相同的。在我的代码中,我使用的是“ CreateEvent”而不是“ Event”

public function showMyTickets()
    {

        $user = Auth::user();
        $ticket= $user->with('TicketOrder','TicketOrder.CreateEvents')->where('user_id',$user->user_id)->get();
        dd($ticket);
    }
  

这就是我在dd($ ticket)中得到的   数据是相关的。现在我不知道该如何找回并且我做对了。
