命名空间App \ Http \ Requests;
使用Illuminate \ Foundation \ Http \ FormRequest;
类UpdateDataRequest扩展了FormRequest { / ** *确定用户是否有权发出此请求。 * * @返回布尔 * / 公共功能authorize（） { 返回true； }

答案 0 :(得分：0)
$request->get('department')的值是什么？
在dd($request);方法内尝试public function update。
您可以在UpdateDataRequest内共享代码吗？
答案 1 :(得分：0)
在控制器上：
df = df.sort_values(by = ‘Profitability’, ascending = False)
df.head(10)
冗余..... 改为：
$Record->department = $request->get('department');
$Record->password =bcrypt($request->get('password')) ;
$Record->department = $request->get('bacs');
看在上帝的份上。对不起，麻烦。
