没有路由匹配控制器
在我的 Rails 3 应用程序中，我有一条在调用 rake 路线时显示如下的路线：
topic_snippets GET /topics/:topic_id/snippets(.:format) {:action=>"index", :controller=>"snippets"}
在 paths.rb 中
resources :topics do
member do
get 'get_topics'
end
resources :snippets, :only => [:index]
end
在我看来，我按如下方式引用该路线（其中 @name =“snippets”）：
<%= send("topic_#{@name}_path")%>
执行上一行时，我收到以下路由错误，不知道为什么：
No route matches {:controller=>"snippets"}
更新：我发现了另一个问题，其响应似乎暗示上述内容应该有效：使用 Rails 动态构建 RESTful 路由
谢谢

In my rails 3 app, I have a route which shows up as follows while calling rake routes:
topic_snippets GET /topics/:topic_id/snippets(.:format) {:action=>"index", :controller=>"snippets"}
In routes.rb
resources :topics do
member do
get 'get_topics'
end
resources :snippets, :only => [:index]
end
In my view, I am referencing this route as follows (where @name = "snippets"):
<%= send("topic_#{@name}_path")%>
When executing the previous line, I get the following routing error, not sure why:
No route matches {:controller=>"snippets"}
Update: I found another question whose responses seem to imply that the above should work: Dynamically construct RESTful route using Rails
Thanks

好的，我找到了 - Ryan 的评论提供了线索。
我没有传递@topic，这是必需的。如果我删除@topic，它会尝试访问没有路由的/snippets/。在调用此行之前，我将 @topic 设置为有效主题，并且它有效。谢谢，瑞安！
OK, I found it - Ryan's comment provided the clue.
I wasnt passing in @topic, which is required. If I remove @topic, it tries to just get at /snippets/ which doesn't have a route. I set @topic to a valid topic before calling this line and it works. Thanks, Ryan!
你尝试过吗
