如何让我的应用程序转到此自定义视图？
我的视频控制器中有这个自定义操作：
def upvoted_songs
@votes = current_user.videos_votes.where("value = 1")
@videos = @votes.videos.page(params[:page]).per(15)
end
这是我的路线：
resources :videos do
member do
put 'topic_update'
get 'upvoted_songs'
end
end
我的视频索引视图中的此链接：
<%= link_to "Upvoted Songs", videos_path, :action => "upvoted_songs", :class => "upvoted_songs chosen_home_option" %>
以及一个名为videos/upvoted_songs.html.erb的视图文件。
为什么链接不直接指向 upvoted_songs.html.erb 视图，而是保留在视频索引视图上？
更新：
这些是我的routes.rb：
root :to => "videos#index"
resources :video_votes
resources :videos do
resources :comments
member do
put 'topic_update', :on => :member
get 'upvoted_songs', :on => :collection, :as => 'upvoted'
end
end
resources :comment_titles
resources :users
resources :profiles
resources :genres
resources :topics
resources :topicables
resource :session
我最初收到此错误：
ArgumentError
can't use member outside resource(s) scope
然后刷新页面后，我收到此错误：
ActionController::RoutingError in Videos#index
Showing /rubyprograms/dreamstill/app/views/videos/_video.html.erb where line #22 raised:
No route matches {:action=>"show", :id=>#<Video id: 485, title: "I'm Ready For You", description: nil, embed_code: nil, thumbnail_url: nil, released: nil, user_id: 57, created_at: "2011-04-02 08:47:36", updated_at: "2011-04-09 22:42:48", video_url: "http://www.youtube.com/watch?v=wy86KNtOjVg", video_votes_count: 0, vote_sum: 3, rank_sum: 28927.724512>, :controller=>"videos"}
22: <%= link_to video.title, video_path(video), :class => "normal" %>
I have this custom action in my videos controller:
def upvoted_songs
@votes = current_user.videos_votes.where("value = 1")
@videos = @votes.videos.page(params[:page]).per(15)
end
this is my routes:
resources :videos do
member do
put 'topic_update'
get 'upvoted_songs'
end
end
And this link in my videos index view:
<%= link_to "Upvoted Songs", videos_path, :action => "upvoted_songs", :class => "upvoted_songs chosen_home_option" %>
and a view file called videos/upvoted_songs.html.erb.
Why doesn't the link direct to the upvoted_songs.html.erb view but rather stay on the video index view?
UPDATE:
These is my routes.rb:
root :to => "videos#index"
resources :video_votes
resources :videos do
resources :comments
member do
put 'topic_update', :on => :member
get 'upvoted_songs', :on => :collection, :as => 'upvoted'
end
end
resources :comment_titles
resources :users
resources :profiles
resources :genres
resources :topics
resources :topicables
resource :session
I initially get this error:
ArgumentError
can't use member outside resource(s) scope
Then after refreshing the page, I get this error:
ActionController::RoutingError in Videos#index
Showing /rubyprograms/dreamstill/app/views/videos/_video.html.erb where line #22 raised:
No route matches {:action=>"show", :id=>#<Video id: 485, title: "I'm Ready For You", description: nil, embed_code: nil, thumbnail_url: nil, released: nil, user_id: 57, created_at: "2011-04-02 08:47:36", updated_at: "2011-04-09 22:42:48", video_url: "http://www.youtube.com/watch?v=wy86KNtOjVg", video_votes_count: 0, vote_sum: 3, rank_sum: 28927.724512>, :controller=>"videos"}
22: <%= link_to video.title, video_path(video), :class => "normal" %>

要查看哪些路由可在您的应用中使用，请在应用根目录的命令行上使用
rake paths。您应该会看到一行引用upvoted_songs的内容。然后像这样使用它：
因为它有一个 member 路由，所以 url 助手将获取一个视频对象（或 id）并生成一个类似于以下内容的 url：
/videos/7/ upvoted_songs但是，您的代码表明您可能正在执行一些不依赖于单个视频对象的操作，并且也不需要在 URL 中使用该对象。因此，您希望将该路由从成员路由更改为集合路由。该 URL 最终会看起来像
/videos/upvoted_songs，并且您不会向其传递视频对象。希望这会有所帮助:)
第 2 部分
删除会员块：
To see what routes are available for use in your app use
rake routeson the command line in the root directory of the app. You should see a line that refers toupvoted_songs.Then use it like so:
Since you have it has a member route the url helper will take a video object (or id) and generate a url that looks something like:
/videos/7/upvoted_songsHowever, your code suggests that you might be doing something that does not rely on a single video object, and wouldn't need that in the URL either. So you would want to change that route from a member route to a collection route. The URL would then end up looking something like
/videos/upvoted_songsand you wouldn't be passing it a video object.Hope this helps :)
PART 2
Remove the member block:
您正在链接到
videos_path，它是“videos#index”的帮助程序。正如 ctcherry 所解释的，您当前的路由使用的是成员路由而不是集合。以下是您要查找的更多内容：
然后您可以使用
upvoted_videos_path代替videos_path。You are linking to
videos_path, which is a helper for "videos#index".As ctcherry explained, your current route is using a member route and not a collection. The following is more what you're looking for:
Then you can use
upvoted_videos_pathin place of justvideos_path.你没有身份证。做一个耙路线| grep upvoted 并看看你的路线应该是什么样子。
它可能类似于
upvoted_songs_video_path(video)You don't have an id. Do a rake routes | grep upvoted and see what your route should look like.
it's probably something like
upvoted_songs_video_path(video)
