Laravel same authorization for update and edit method - php

Question

I would like to keep my authorization as DRY as possibile.
Currently for my update method I am using Laravel 5 FormRequest.
Example:
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
$commentId = $this->route('comment');
return Comment::where('id', $commentId)
->where('user_id', Auth::id())->exists();
}
The problem is that this gets triggered just for update method:
/**
* Update the specified resource in storage.
*
* #param int $id
* #return Response
*/
public function update(UpdateRequest $request, $id)
{
// ...
}
How can I use the same authorize logic for edit method?
Otherwise everyone can just type:
/resources/ID/edit
^
not allowed
Only the owner should see that page, not everyone
Note I can't add that same UpdateForm to the edit method, because otherwise validation could be triggered too
/**
* Show edit form for the specified resource in storage.
*
* #param int $id
* #return Response
*/
public function edit(UpdateRequest $request, $id)
{
// ...
}

You have something called middleware in laravel 5.
You can use it in the route so that it gets executed before the action has been called.
I think for what you need you will have to create your own middleware.
http://laravel.com/docs/master/middleware
After you created one you have to tell laravel to use the middleware and then add it to your route like so
route::get('test', ['middleware' => 'yourmiddleware', 'uses' => 'yourController#index']);
