I have gerated a scaffold_resource for "news" like so:
script/generate scaffold_resource news <fields>
I have also added a route to routes.rb
map.resources :news
I have an application-wide layout that contains a menu with the entry:
<%= link_to("News", news_path) %>
Now, the odd thing is that this generates <applicationurl>/news from
most pages, but the same entry points to <applicationurl>/news/1 from
within the news/1 page and from within the edit page for news 1. Similar
it points to <applicationurl>/2 from the show and edit pages for news 2.
When a news_path occurs anywhere on an news edit or show page, it does
not link to the index action but to the show action for that specific
record.
I have a couple of other models/views/controllers which all work fine,
only the news part shows this odd (and definitely wrong) behavior.
I tried to add :singular => :news to the route definition, but that did
not help.
Is this a bug in RoR?

I would recommend: map.resources :news, :singular => "news_item" Then you can do: <%= link_to item.title, news_item_path(item) %> <%= link_to "All news", news_path %> That will separate the singular from the plural, and it actually makes more sense linguistically too.

When I do > scaffold_resource it works as expected.I agree that it does what''s expected, but that''s not what the OP wants :-) If you look at views/news/show.rhtml, as produced by the scaffolding, you''ll see: <%= link_to ''Edit'', edit_news_path(@news) %> | <%= link_to ''Back'', news_path %> That "Back" link would normally link to the index action (a plural GET), but in this case, news_path has been taken up by the singular, and the :id field is inferred from the current environment. So it''s equivalent to: news_path(2) # for example, if params[:id] is current 2 and if you click on it, it takes you back to the show page you''re already on. That''s why you need to differentiate between singular and plural news. (As tested on Rails 1.2.3.) David -- Q. What is THE Ruby book for Rails developers? A. RUBY FOR RAILS by David A.

That did not seem intuitively right to me. In any case, I have chosen to avoid the confusion and changed the naming alltogether. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That did not seem intuitively right to me.It''s really the other way around: because news_path is a singular resource route, and it requires an :id value, it makes use of the existing value. news_path itself doesn''t change. If you try to put this in index.rhtml: <%= link_to "Attempting link back to showing all news", news_path %> you''ll get an error, because it will be trying to execute news_path but unable to find an :id value. (If my description isn''t consistent with what you''re getting, I''d be interested to hear about it.)> In any case, I have chosen to avoid the confusion and changed the naming > alltogether.That''s definitely the best plan.
