Passing Params to a 301 redirect in rails 2.3

Question

I'm stuck on a Rails 2.3 app trying to redirect some old URLs. I'm new to RoR and know 3+ way better, so I'm having trouble getting this done.

So: http://siteurl.com/foo/:foo_id goes to http://siteurl.com/foo/:foo_id/foo_items

I think I'm close because the end product goes to: http://siteurl.com/foo/foo_id/foo_items but doesn't pass the :foo_id params it actually writes it out!

Any help, or pointers are much appreciated.

In my routes.rb

map.connect '/foo/:foo_id',
      :controller => 'redirect',
      :action => :redirectoldfoo,
      :monkey_tag => ':foo_id'

In my redirect controller:

  def redirectoldfoo
    redirect_to "/auctions/#{params[:monkey_tag]}/catalog_items"
  end

You should not need the :monkey_tag at all, since :foo_id is all you're using anyway.

  map.connect '/foo/:foo_id',
      :controller => 'redirect',
      :action => :redirectoldfoo

  def redirectoldfoo
    redirect_to "/auctions/#{params[:foo_id]}/catalog_items"
  end

Note that in your example you indicated that you were trying to redirect to both /foo/:foo_id/foo_items and then /auctions/:foo_id/catalog_items. I assumed that the second one was closer to the real code, so I left that one in there.
