在null / AdminHomeController.php第26行调用成员函数delete（）：

Question

Using the multi_auth from laravel 5.3 im trying to make a delete/edit/update button.

Im trying to delete an user from the admin dashboard retrieving information from the users table. Actually my first problem is with the destroy function.

This is my destroy route:

Route::get('{id}',[
    'as' => 'admin.destroy',
    'uses' => 'AdminHomeController@destroy'
]);

This is my controller from admin:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\User;

class AdminHomeController extends Controller
{
    public function __construct()
    {
        $this->middleware('admin.user');
    }

    public function index()
    {
        $users = User::all();

        return view("admin-home")->with('users', $users);
    }

    public function destroy($id)
    {
        $users = User::find($id);
        $users->delete();

        Flash::error('El usuario ' . $users->name . '$ ha sido eliminado con exito!');
        return redirect()->route('admin-home');
    }
}

View with delete button:

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            <div class="col-sm-offset-2 col-sm-8">
                @if (count($users) > 0)
                    <div class="panel panel-default">
                        <div class="panel-heading">
                            Todos los Usuarios
                        </div>
                        <div class="panel-body">
                            <table class="table table-striped user-table">
                                <thead>
                                    <th>Nombre:</th>
                                    <th>&nbsp;</th>
                                    <th>Email:</th>

                                    <th>&nbsp;</th>
                                </thead>
                                <tbody>

Check $id in $users = User::find($id); $users->delete();

Object $users is null because user didn't found in database or $id is incorrect
