Rails 3 link_to 路由（编辑）嵌套资源
抱歉，如果其他地方有人问过这个问题，但我无法弄清楚。我有一个包含版块、主题和回复的论坛。我正在尝试从显示主题视图中编辑和删除回复。这是结构：
resources :sections do
resources :topics do
resources :replies
end
end
所以我做了一个 rake 路线来查看我在哪里链接我的编辑回复。我看到它的 edit_section_topic_reply 并在我的 link_to 中添加了 _path 。现在这是我无法弄清楚的。我传递什么参数？不应该是这样吗：
<%= link_to 'Edit', edit_section_topic_reply_path(@reply, @topic, @section) %>
当我这样做时，我在 Topics#show 中收到 ActionController::RoutingError 。
No route matches {:topic_id=>#<Topic id: 2, section_id: 2, user_id: nil, subject: "subject", body: "body", created_at: "2011-03-04 08:37:37", updated_at: "2011-03-04 21:37:16">, :controller=>"replies", :action=>"edit", :section_id=>nil, :id=>#<Section id: 2, name: "Section", description: "Section Description", created_at: "2011-03-04 07:50:56", updated_at: "2011-03-04 07:50:56">}
看起来好像没有传递ID，但是之前的嵌套，我的新主题工作正常
new_section_topic_reply_path(@topic, @section)
Sorry if this has been asked elsewhere, but I can't figure this out. I have a forum with sections, topics, and replies. I'm trying to edit and delete replies from the show topic view. This is the structure:
resources :sections do
resources :topics do
resources :replies
end
end
So I do a rake routes to see where I'm linking my edit reply. I see that its edit_section_topic_reply and in my link_to I add _path to it. Now this is what I can't figure out. What parameters am I passing it? Shouldn't it be:
<%= link_to 'Edit', edit_section_topic_reply_path(@reply, @topic, @section) %>
I get a ActionController::RoutingError in Topics#show when I do this.
No route matches {:topic_id=>#<Topic id: 2, section_id: 2, user_id: nil, subject: "subject", body: "body", created_at: "2011-03-04 08:37:37", updated_at: "2011-03-04 21:37:16">, :controller=>"replies", :action=>"edit", :section_id=>nil, :id=>#<Section id: 2, name: "Section", description: "Section Description", created_at: "2011-03-04 07:50:56", updated_at: "2011-03-04 07:50:56">}
It seems like it isn't passing IDs, but the nest before, my new topic works fine
new_section_topic_reply_path(@topic, @section)

我真的不喜欢
link_to帮助器的这一方面。为了使您的代码更具可读性且不易出错，我建议您明确要传入的 ID。由于参数乱序，我遇到了太多微妙且看似疯狂的错误 。一个
link_to。I really dislike this aspect of the
link_tohelper. In the interest of making your code more readable and less prone to error, I would suggest that you be explicit about which IDs you are passing in.I've run into too many subtle and seemingly insane bugs due to params being out of order in a
link_to.编辑链接的另一种方法
One more way for edit link
我认为正确的顺序应该是：
I think the right order should be:
