Why can't he see the model? error Class 'Task' not found?

Question

Laravel

I just started to learn Laravel, according to this guide Link
In the paragraph Create a task Link
there are lines:

$task = new Task;
    $task->name = $request->name;
    $task->save();

But when trying to send data from / to /task , it gives an error

Class 'User' not found ?

before that, step 2, I created the Task model, but for some reason he does not see it,
the guide uses version 5.2, I think that there are some changes in 5.3, help!!
PS also did not find the routes.php file in htt, which is mentioned in this part of the manual
, created routes in routes/web.php

Answer 1

What version of Laravel are you using? With $input = $request->all(); Throws error Call to undefined method Illuminate\Support\Facades\Request::all()

Use:
Or if you have a standard alias:
use Request;

Answer 2

php artisan make:auth
?
