尝试创建一个视频游戏评论网站进行练习。遇到了缺少关键/没有路线匹配的问题。
下面是我的游戏，评论控制器。评论嵌套在游戏中。非常感谢提前：）
编辑：
错误是：
没有路由匹配{：action =＆gt;＆＃34;更新＆＃34;，：controller =＆gt;＆＃34;评论＆＃34;，：game_id =＆gt; 3，：id =＆gt; nil}丢失必填项：[：id]
以下完整错误代码：

**也有Show视图的问题。我认为它的删除行动 ***你也可以看看我的表格部分提交审查？我基本上试图渲染文本区域在显示视图中呈现，然后一旦提交，就会显示在文本区域下方。
我可以添加评论并保存，但一旦提交，我就会收到错误消息。我去了rails控制台，看到评论被保存了 - 但只是好奇我的逻辑是否正常。

答案 0 :(得分：0)
我认为错误发生在这里：edit_game_path
编辑路径需要模型ID才能工作，因此您需要传递它：
edit_game_path(@game)
答案 1 :(得分：0)
您必须在show.html.erb
<%= link_to "delete comment", game_review_path(review.game_id), method: :delete %>
到
<%= link_to "delete comment", game_review_path(review, review.game_id), method: :delete %>
