Laravel:多个where子句中许多一对多的关系

问题描述:

我不能对laravel创建此SQL查询:Laravel:多个where子句中许多一对多的关系

select * from `events_theatre` where 
    event_id IN (
     select id from events where (`events`.`id` = `events_theatre`.`event_id` and `user_id` = 1 and `event_type` ='theatre') and `events`.`deleted_at` is null 
    ) 
    or event_id IN (
     select id from events inner join events_managers on events.id = events_managers.event_id and events_managers.user_id = 1 
    ) 
    and `events_theatre`.`deleted_at` is null 

的Events_Theatre模型有这种关系:

public function event() 
{ 
    return $this->hasOne('App\MyEvent', 'id'); 
} 

虽然MyEvent模型具有以下关系:

public function managers() 
{ 
    return $this->belongsToMany('App\User', 'events_managers', 'event_id', 'user_id'); 
} 

实际上Events_Theatre模型是Event模型,Ev模型ent模型可能有许多管理者,但只有1个管理员。

我需要获取Events_Theatre(及其MyEvent),其用户是管理员或管理员之一。

我试着用这个雄辩查询:

$list = App\Events_Theatre::whereIn('event_id', function ($query) { 
    $query 
     ->where(['user_id' => Auth::id(), 'event_type' => 'theatre']) 
     ->orWhereHas('managers', function ($query) { 
      $query->where('user_id', Auth::id()); 
     }); 
}); 

但我得到这个SQL查询:

select * from `events_theatre` where 
exists (
    select * from `events` where (
     `events`.`id` = `events_theatre`.`event_id` and `user_id` = 1 and `event_type` = 'theatre' 
    ) or exists (
     select * from `users` inner join `events_managers` on `users`.`id` = `events_managers`.`user_id` where `events_managers`.`event_id` = `events`.`id` and `user_id` = 1 
    ) 
    and `events`.`deleted_at` is null 
) and `events_theatre`.`deleted_at` is null 

但它错了。我该如何解决这个问题?

感谢

我得到了答案。这是雄辩的代码,我用:

$list = Events_Theatre::whereHas('event', function ($query) { 
    $query 
     ->where(['user_id' => Auth::id(), 'event_type' => 'theatre']); 
})->orWhereHas('event', function ($query) { 
    $query 
     ->whereHas('managers', function ($query) { 
      $query->where('user_id', Auth::id()); 
     }); 
})->get();

在表是你的域user_id说明和EVENT_TYPE,第一选择到存在吗? –

你能说清楚你试图寻找什么样的条件。从你粘贴的所有不同的sql推断出来有点令人困惑。 –

我需要获取其用户是管理员或管理员之一的Events_Theatre(及其MyEvent)。 –

你可以试试has方法

App\Events_Theatre::has('event')->orhas('managers')->get();
