Laravel：单击按钮后更新数据库出现问题

Question

我有问题：我构建了一个应用程序，我的数据库中有2个表：习惯和用户。用户有一个名为points的字段，点击“添加点”按钮后，我想增加该值。我在HabitsController中添加了一个名为addPoints的方法，并在视图中添加了按钮，但是我收到一条错误消息：MethodNotAllowedHttpException没有消息。有我的代码。

HabitsController.php

路线/ web.php

Route::get('/', 'PagesController@index');
Route::get('/about', 'PagesController@about');

Route::resource('habits', 'HabitsController');
Auth::routes();

Route::get('/dashboard', 'DashboardController@index');

我将不胜感激任何帮助。 :)

更改

{{Form::hidden('_method', 'POST')}}

至

{{Form::hidden('_method', 'PUT')}}
