My controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\User;
use DB;

class PostController extends Controller
{
    //
    public function mapost()
    {

       
        $data = Auth::user()->Announce::orderBy('created_at', 'DESC')->get();

        return view('users.mapost',['data'=>$data]);
    }
}

My route in web.php

Route::get('users/mapost', 'PostController@mapost')->name('users.mapost');

I don`t know where I am getting this wrong, i will appreciate any help thanks in advance

CodePudding user response：

Look at this line:

$data = Auth::user()->Announce::orderBy('created_at', 'DESC')->get();

Here you attempt to call the orderBy method of the Auth::user()->Announce class and of course, such class does not exist. It would make sense to do something like this:

Announce::where('user_id', $youruserid)->orderByDesc('created_at');
