Laravel中更新错误：找不到类'App \ Http \ Controllers \ App \ Category'

Question

我是laravel的新手，我正在尝试使用以下代码更新我的表。但收到以下错误

  

类'App \ Http \ Controllers \ App \ Category'未找到

我的代码是

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Collection;
use App\Category;
class CategoryController extends Controller
{


    public function UpdateCategory()
    {
        $category = App\Category::find(3);

        $category->name = 'Women';

        $category->save();
    }
}

Answer 1

试试这个

$category = Category::find(3);

Answer 2

fixedStr =    
1.12345678e-001

  

您已将模型包含在控制器中。所以你不需要再次包括

use App\Category;

  

只需使用此

即可

Answer 3

更改

$category = App\Category::find(3);

要

$category = Category::find(3);
