Laravel 8 - 必须满足多个 where 子句

Question

我有一张商务桌和一张员工桌。

我正在尝试查看员工表中是否已经存在具有相同 user_id 和 business_id 的用户，但是，使用我当前的代码我不确定如何执行此操作。

我的代码：

if (BusinessEmployee::where('user_id', Auth::user()->id)->where('business_id', $business->id)) {
        dd('already in business');
    }

Answer 1

if (BusinessEmployee::where('user_id', Auth::user()->id)->where('business_id', $business->id)->exists()) {
        dd('already in business');
}

或

$business = BusinessEmployee::where('user_id', Auth::user()->id)->where('business_id', $business->id);
        
        if($business->exists())
        {
          dd('already in business');
        }
