                  </form>

控制器：

  public function edit(Category $category)
  {
    $categories = Category::findOrFail($category->id);
    return view('admin.category.edit', compact('categories'));
  }

如果您使用的是资源控制器，那么您的编辑功能应如下所示：

 public function edit(Category $category)
 {
     return view('admin.category.edit', compact('category'));
 }

您两次运行相同的查询。另外，请确保您使用的是资源路由：

 Route::resource('category', 'CategoryController');

请参见Laravel Docs
