我的破坏函数编码如下：

 public function destroy($id)
{
    $status = 'success';
    $statusMsg = 'Data Deleted';

    try {
        $category = Category::find($id);
        $category->delete();

    } catch (QueryException  $e) {
        $status = 'success';
        $statusMsg = $e;
        return  back();

    }
    $category = Category::find($id);
    $category->delete();
    return redirect()->route('category.index')->with($status,$statusMsg);

}
