使用表单请求时路由模型绑定失败

Question

当我使用 FormRequest 验证请求时，Route 模型绑定失败。更具体地说，当我尝试访问表单请求中的参数并给出以下错误时：

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name:\"moniersa\"' in 'where clause' 
(SQL: select count(*) as aggregate from `users` where `email` = a.monier2130@gmail.com and 
`name:\"moniersa\"` <> {\"id\":5 and `email:\"a`.`monier2130@gmail`.`com\"` = 
email_verified_at:null and `admin:1` = verified:0 and `created_at:\"2020-02-11 22:33:33\"` = 
updated_at:\"2020-02-11 23:17:40\"})

更新方法的代码：

public function update(User $user, UpdateUserRequest $request)
    {
        $data = $this->extract_data($request);
        $user->update($data);
        return response()->json(['data' => $user], 200);
    }

Update请求中规则函数的代码：

public function rules()
    {
        return [
            'name' => 'required|string|min:3|max:40',
            'email' => 'required|email|unique:users,email,' . $this->user,
            'password' => 'required|string|min:9|confirmed'
        ];
    }

每当我从更新方法中删除User 提示或从更新请求文件中删除$this->user 时，一切正常。关于问题出在哪里的任何线索？

路由模型绑定意味着您不再需要使用$user = User::findOrFail($user);，

public function update(User $user, UpdateUserRequest $request)
    {

        $user = User::findOrFail($user);// this line is redundant, you can remove it.
        $data = $this->extract_data($request);
        $user->update($data);
        return response()->json(['data' => $user], 200);
    }
