從多個表中檢索數據

Question

我有兩個表（用戶和角色）具有一對一關系用戶模型

public function user_role()
{
    return $this->hasOne('App\Role');
}

控制器中的功能

   public function update_role($id)
{

    $role = User::with('user_role')->find($id);
    return view('update_role') -> with ('role',$role);
}

update_user視圖

{{$role -> name}}
{{$role -> setting}}
{{$role -> images}}

但是檢索到的數據只是用戶表中的用戶名，而不是角色表中的用戶設置和用戶圖像

Answer 1

嘗試這個

{{$role->user_role->name}}         //this is if you are getting the role name
{{$role->user_role->setting}}      //this is if you are getting the role setting
{{$role->user_role->images}}       //this is if you are getting the role images

嘗試在控制器中更改變量的名稱，以便在我們將其帶到視圖時具有正確的含義，因為您正在為用戶帶來user_role。

//controller
$user= User::with('user_role')->find($id);
return view('update_role') -> with ('user',$user);

//view - accessing it will be as simple as
Username {{$user->username}}<br>             //accessing column in your user table
Role     {{$user->user_role->name}}<br>      //accessing column in your user_role
Setting  {{$user->user_role->setting}}<br>
Image    {{$user->user_role->images}}
