Method [validate] does not exist error in laravel 5.2

Question

I have just started learning laravel. I am using laravel 5.2.29 I am getting error when running the code:

Whoops, looks like something went wrong. BadMethodCallException in Controller.php line 107: Method [validate] does not exist.

Here is the error line displayed:

My route code:

<?php


Route::group(['middleware' => ['web']], function(){

Route::get('/', function () {
    return view('home');
})->name('home');

Route::group(['prefix'=>'do'], function(){


    Route::get('/{action}/{name?}', [
        'uses' => 'NiceActionController@getNiceAction', 
        'as' => 'niceaction'  //router name same as ->name('routername')
    ]);



    Route::post('/', [

        'uses' => 'NiceActionController@postNiceAction',
        'as'   => 'benice'

    ]);

});

});

My Controller code is given below:

<?php

namespace App\Http\Controllers;


use Illuminate\Routing\Controller;
use \Illuminate\Http\Request;

class NiceActionController extends Controller
{
public function getNiceAction($action, $name=null)
{
    return view('actions.'.$action, ['name' => $name]);

}

public function postNiceAction(Request $request)
{

    $this->validate($request, [

           'action' => 'required',
           'name' =>'required'

       ]);

            return view('actions.nice',            ['action'=>$request['action'],'name'=>$this->transformName($request['name'])]);

}
private function transformName($name)
{
    $prefix='KING';
    return $prefix.strtoupper($name);
}
}

My base main controller "controller" has following code:

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesResources;


class Controller extends BaseController
{
use AuthorizesRequests, AuthorizesResources, DispatchesJobs, ValidatesRequests;

}

Am i missing anything????

Answer 1

You need to extend the App\Http\Controllers\Controller class which uses the necessary ValidatesRequests trait that implements the required validate method.

So in your NiceActionController class just remove this line:

use Illuminate\Routing\Controller;

That way this line:

class NiceActionController extends Controller

Will extend the proper Controller class from the same namespace (more precisely App\Http\Controllers\Controller), which includes the necessary traits and which already extends that Illuminate\Routing\Controller class (aliased as BaseController).

Answer 2

To display errors, simply remove the line below and the closing )}

Route::group(['middleware' => ['web']], function(){

As of 5.2, routes.php is by default already called in the context of a ['middleware'=>'web'] by RouteServiceProvider. // But in routes.php default generation of auth routes, the Route::group call is still happening by default - so if you delete that Route::group // declaration from routes.php the application then correctly shows errors.
