How to update single column in laravel - updates

Question

I am new in Laravel and I'm trying to create an application. I have created a form and I use a controller to store this form into my database.The form has a drop-down field named "Status".
The "Status" is like "Categories" so I need to change this without changing anything else. I am trying to write the code but I am doing something wrong. You can see my code below:
Controller:
public function show($id)
{
$servicedevice = DeviceService::findOrFail($id);
return view('device_service.show', compact('servicedevice', $servicedevice));
}
public function devicestatus(Request $request)
{
$devstat = DeviceService::FindOrFail($servicedevice->id);
$devstat->status_id = $request->device_id;
$devstat->save();
return back();
}
View:
{!! Form::open(['action' => 'DeviceServiceController#devicestatus']) !!}
{!! Form::select('status_id', $statuslist, null, [
'class' => 'js-example-basic-single',
'style' => 'width:50%'
]) !!}
{!! Form::hidden('id', $servicedevice->id) !!}
{!! Form::submit('ok', ['class' => 'btn btn-sm btn-flat btn-warning']) !!}
{!! Form::close(); !!}
Route:
Route::get('/devicestatus', 'DeviceServiceController#devicestatus');
When I try to change The "Status", returns the following error
MethodNotAllowedHttpException in RouteCollection.php line 218:

Can you help me please?

Answer 1

The error message and stack trace tells you exactly what happened:
MethodNotAllowedHttpException
...
RouteCollection->methodNotAllowed(array('GET', 'HEAD'))
You are submitting a form (which is POST method by default) but you only define the route as Route::get.
You need to change that to Route::any or define a second route Route::post to the same URL but with a different method call.
