我有这个控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Category;

class CategoriesController extends Controller
{

    public function index()
    {
        $categories = Category::all();
        
        return view('home', ['categories'=> $categories]);
    }
}

而我的blade是这样的（他的调用“home.blade.php”）

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/Swiper/4.3.3/css/swiper.min.css">
    <script src="https://cdnjs.cloudflare.com/ajax/libs/Swiper/4.3.3/js/swiper.min.js"></script>
    <div class="container">
        <div class="row text-center mb-3">
            <div class="col-md-12">
                <h2>Categorias</h2>
                
                <hr>
                @foreach($categories as $cat)
                    <button>{{ $cat->CATEGORIA_NOME }}</button>
                @endforeach
            </div>
        </div>

型号：

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use HasFactory;

    protected $fillable = ['CATEGORIA_NOME', 'CATEGORIA_DESC'];
    protected $table = 'CATEGORIA';
    protected $primaryKey = 'CATEGORIA_ID';
    protected $timestamp = false;

    public function categorias()
    {
        return $this->hasMany(Product::class, 'CATEGORIA_ID');
    }
}

但我仍然收到错误：未定义的变量$categories
我试着用

$categories = Category::all();
    
    return view('home', ['categories'=> $categories]);

或
返回视图（'home'）-〉with（'categories'，$categories）;
但没有成功
