Laravel : Method [index] does not exist on [App\Http\Controllers\admin\PostsController]

Question

This answer doesn't solve my problem Route::controllers - Method [index] does not exist on [App\Http\Controllers

In web.php

Route::prefix('admin')->group(function () {
    Route::resource('post', 'admin\PostsController');
});

in app/Http/Controllers/admin

I have PostsController.php

which contains

<?php

namespace App\Http\Controllers\admin;

use App\Model\Post;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class PostsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        //
        $posts = \App\Post::all();
        return view('admin.posts',['posts'=>$posts]);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create(Request $request)
    {
        //
        $post = new Post;

        $post->content = $request->input('descr');

        $post->save();
    }

When I go to this url http://127.0.0.1:8000/admin/post

I get the following error

BadMethodCallException Method [index] does not exist on [App\Http\Controllers\admin\PostsController].

call_user_func_array
…
/vendor/laravel/framework/src/Illuminate/Routing/Controller.php 56 

 public function callAction($method, $parameters)
    {
        print_r($this);
        echo $method;die();
        return call_user_func_array([$this, $method], $parameters);
    }

//prints

App\Http\Controllers\admin\PostsController Object ( [middleware:protected] => Array ( ) ) index

php artisan prints the following

php artisan route:list 

|        | GET|HEAD  | admin/post             | post.index   | App\Http\Controllers\admin\PostsController@index   | web

Answer 1

Maybe you have Ambiguous class in your controllers, that means you may have same class name in different controllers. To solve that problem, run these commands

 1. composer update 
 2. composer dumpautoload
 3. php artisan config:cache
 4. php artisan view:clear

Make sure that composer update runs successfully without errors. If errors are mentioned in the console, correct all of them where they occur in your codebase.

Answer 2

Using laravel version 5.4 , i ran this commands

php artisan make:controller admin/PostsController --resource

in web.php routes file added this

Route::prefix('admin')->group(function () { Route::resource('post', 'admin\PostsController'); });

controller file

namespace App\Http\Controllers\admin;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class PostsController extends Controller
{
 /**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
  public function index()
  {
    echo "call to index";
  }
  ........
   other functions

}

works fine for me
