事情，我尝试了很多东西根本不起作用，当我从我的表格发出我的帖子请求时，不知何故我的终端出现了这种错误：

所以我有一个使用该设计创建的 Games_controller 用户和一个 Bookings_controller。在我的显示页面中，我看到了我的预订选项，但不知何故，当我点击提交按钮时，没有任何反应，我得到了我之前分享的错误，我不确定为什么。我不明白的是，为什么我没有任何类型的标志，比如我的预订根本没有被保存，或者如果它保存了，我应该有某种标志。所以经过深思熟虑，我决定在这里问。
因为我以 _show.html.erb 的形式定义了我的 games_id。因此，如果有人对此有解决方案，那就太好了
