Routes are cool. I was especially pleased when I found out that link_to
and the like use them backwards to form the URLs I intend. I just
thought I''d mention that.
But anyway, I am having trouble with one of my routes, or more
specifically, the variable in my route. I have this line in routes.rb:
map.connect ''news/:page'', :controller =>
''news''
In my news_controller.rb file I have this, which is basically what was
there from when I generated the scaffolding:
@news_item_pages, @news_items = paginate :news_item, :per_page => 2,
:order_by => ''postdate DESC''
In the view, I have the following line to generate the "Next page"
link:
<% if @news_item_pages.current.next %>
<%= link_to "Next page", :page =>
@news_item_pages.current.next %>
<% end %>
Now, when I visit the page with the URL /news?page=2 everything works
swell and the "Next page" links shows up properly. When I visit the
page
with the URL /news/2 things mess up. I get the following error, at the
link_to line:
undefined method `paginator'' for "2":String
The "2":String part changes depending on whether I go to /news/3 or
/news/17. I do not understand why I get this problem. What do I do?
Sincerely,
Tom Reinhart

Hey, Railers. I did not have any luck last time I posted this message here, but I really have no idea where else to ask. I have asked a few times about this issue in the IRC channel, and read a lot of the documentation, but I still feel that I am missing something obvious. My personal belief is that it has something to do with scope, but I cannot be sure.

I do not understand why I get this problem. What do I do?I made a patch for that bug: http://dev.rubyonrails.com/ticket/1184 Basically, the Pagination_links helper sends a paginator object to the link_to function. This normally works fine because it converts the paginator to a string when forming the URL (action?page=2). However, when it''s in a route, it does some comparison between the Paginator and the default value of that path parameter, which causes that error that you get. My patch forces it to send a string. I also added a :link_prefix option to pagination_links so I could get sweet flickr-style URLs (action/page2). Let me know if it works out. -- rick http://techno-weenie.net
