Parameter count error when using #can Blade directive - php

Question

I'm having the following error when I try to check a permission using policies:
Too few arguments to function App\Policies\AnswerPolicy::view(), 1 passed in /Users/georgio/Projects/Laravel/municipality-app/vendor/laravel/framework/src/Illuminate/Auth/Access/Gate.php on line 710 and exactly 2 expected (View: /Users/georgio/Projects/Laravel/municipality-app/resources/views/layouts/loggedin.blade.php)
AnswerPolicy
<?php
namespace App\Policies;
use App\Answer;
use App\User;
use Illuminate\Auth\Access\HandlesAuthorization;
class AnswerPolicy
{
use HandlesAuthorization;
public function view(User $user, Answer $answer)
{
return true;
}
public function edit(User $user)
{
return true;
}
public function create(User $user)
{
return true;
}
public function delete(User $user)
{
return true;
}
public function update(User $user)
{
return true;
}
}
AnswersController
<?php
namespace App\Http\Controllers;
use App\Question;
use App\Answer;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class AnswersController extends Controller
{
public function index()
{
$this->authorize('view');
return view('answers.show')->with('questions', Question::all());
}
public function create($questionId)
{
$this->authorize('view-submit-answer');
return view('answers.create')->with('question',Question::find($questionId));
}
public function store()
{
$this->authorize('');
$this->validate(request(),[
'answer' => 'required',
]);
$data = request()->all();
$answer = new Answer();
$answer->answer = $data['answer'];
$answer->question_id = $data['question_id'];
$answer->user_id = Auth::id();
$answer->save();
return redirect('/questions/answers');
}
public function edit($answerId)
{ $this->authorize('view-edit-answer');
return view('answers.edit')->with('answer', Answer::find($answerId));
}
public function update($answerId)
{
$this->validate(request(),[
'answer' => 'required',
]);
$data = request()->all();
$answer = Answer::find($answerId);
$answer->answer = $data['answer'];
$answer->save();
return redirect('/answers-question');
}
public function destroy($questionID)
{
$this->authorize('delete-answer');
$answer = Answer::where('question_id', $questionID)->where('user_id', Auth()->id());
$answer->delete();
return redirect('/questions/answers');
}
}
loggedin.blade.php
This is only the part of my code that is causing the error
#can('view', App\Answer::class)
<li>
<a href="/questions/answers">
<span><i class="fa fa-pencil"></i></span>
<span>Answer Question</span>
</a>
</li>
#endcan
I even tried replacing $answer with App\Answer::class and I still had the exact same error.

Answer 1

The documentation says
When defining policy methods that will not receive a model instance, such as a create method, it will not receive a model instance. Instead, you should define the method as only expecting the authenticated user
I don't see an Answer instance inside your #can statement there. Does one exist? If so, you should be doing this:
#can('view', $answer)
Or, if one doesn't exist at that point, define your method like this
public function view(User $user)
And call it like this:
#can('view', \App\Answer::class)
