Laravel: Update value of a column on button click

Question

Hello i'm still new to laravel and I've searching the web for almost 3 hours about this issue I have I tried many things but it didn't work.

So basicly I have a page with a button , when I click that button "Approve" I want to update the value from 0 to 1 (the column is of type boolean). This is my controller :

public function approve($id){
    $training = Training::find($id);
    $training->update(['Approved' =>'1']);


    // $training->Approved = 1;
   // $training->save();
    return redirect('/trainings')->with('success', 'Training Approved');
}

This is page section with the button it's in the folder trainings and has the name " show.blade.php" :

 {!!Form::open(['action' => ['TrainingsController@approve',$training->TrainingsID], 'method' => 'POST','class' => 'pull-left'])!!}
            {{Form::hidden('_method','PUT')}}
            {{Form::submit('Approve',['class' => 'btn btn-success'])}}

    {!!Form::close()!!} 

and the routes (I guess this is the part I'm doing wrong):

Route::post('/trainings',['as' =>'trainings.show', 'uses' => 'TrainingsController@approve']);

The error I get when clicking the button is this :

Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException

Thank you for your Help

Since the route is post, you should change form method to post too:

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

Or:

{!! Form::open(['method' => 'post', 'action' => ....

You also need to add id to the route definition:

Route::post('trainings/{id}', ['as' => 'trainings.show', 'uses' => 'TrainingsController@approve']);
