Error Action App\Http\Controllers\[email protected]_name not defined. Why does it occur?

Question

Laravel

Route

Route::get('admin/students', '[email protected]_avatar');

Controller

public function update_avatar()
    {

    }
// ну тут просто объявленная функция

view

<a href="{{action('[email protected]_avatar')}}">Link name/Embedded Button</a>

It gives an error Action App\Http\Controllers\[email protected]_avatar not defined
I don't understand what's wrong.

Answer 1

First:
Functions are called through camelCase with a small bull, and variables through snack_case (PSR-2).
Secondly:
Route can be called in a bunch of ways:
one.

<a href="{{ route('updateAvatar') }}">Link name/Embedded Button</a></li>

2.

<a href="{{ action('[email protected]') }}">Link name/Embedded Button</a>

- If you have

FrontEndController

is in namespace

App\Http\Controllers

3.

<a href="{{ url('admin/students'') }}">Link name/Embedded Button</a></li>

4.

<a href="/admin/students'">Link name/Embedded Button</a></li>

Answer 2

so FrontEndController or all the same StudentsController?
In the route one thing, in the link another. Look somewhere they wrote something wrong
