laravel请求验证数据更新 [英] laravel request validation on updating of data

问题描述

我有一个请求验证，用于我的数据更新

I have a request validation for my updating of data

public function rules()
{
   return [
      'name' => 'required|string|max:255',
      'email' = 'required|string|email|max:255|unique:users,email,'.$this->id,
      'password' => 'min:6',
   ];
 }

这是我的控制器

public function update(UpdateUserInfo $request, $id){
        $user = User::findOrFail($id);
        $user->name = $request->input('name');
        $user->email = $request->input('email');
        $user->role_id = 2;
        if($request->input('password')){
            $user->password = Hash::make($request->input('password'));
        }
        return $user->save() ?: new UsersResource($user);
    }

但是我有一个错误提示The Response content must be a string or object implementing __toString(), "boolean" given.

However i have an error saying The Response content must be a string or object implementing __toString(), "boolean" given.

在我进行验证之前，是在控制器本身上

Before my validation is on the controller itself

   public function update(Request $request, $id)
    {
        $this->validate($request, [
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users,email,'.$id,
            'password' => 'min:6',
        ]);
        $user = User::findOrFail($id);
        $user->name = $request->input('name');
        $user->email = $request->input('email');
        $user->role_id = 2;
        if($request->input('password')){
            $user->password = Hash::make($request->input('password'));
        }
        if($user->save()){
            return new UserResource($user);
        }
    }

，它工作正常.现在，我只想将验证与控制器分开.

and it is working fine. And right now i just want to separate the validation from the controller.

我认为问题出在电子邮件的验证上

I think that the problem is on the validation of email

'email' = 'required|string|email|max:255|unique:users,email,'.$this->id,

但是我不知道如何通过更新方法传递ID

but i dont know how to pass the id from the method of update

推荐答案

要解决此问题，我们需要先了解该错误:

To fix the issue, we need to understand the error first:

响应内容必须是实现的字符串或对象 __toString()，给出布尔值".

The Response content must be a string or object implementing __toString(), "boolean" given.

这表明问题出在控制器的响应(返回)上.

It indicates that the problem is in the response (return) of your controller.

由于$user->save()成功返回true，因此此行会导致您的控制器在更新成功时返回布尔值，而Laravel期望string or object implementing __toString():

Since $user->save() returns true on success, this line causes your controller return boolean when the update success while Laravel expects string or object implementing __toString():

return $user->save() ?: new UsersResource($user);

因此，您可以尝试解决此问题的方法是简单地还原以前的返回值(您可以保留其余代码):

So what you can try to fix this is by simply restoring the previous return (you can keep the rest of the code):

if($user->save()){
    return new UserResource($user);
}

或者简单地:

$user->save();
return new UserResource($user);

因为我们希望验证错误会引发异常.

Because we expect exception to be thrown on validation error.
