[Rails-core] Re: bug in routes ???

Sat, 23 Sep 2006 04:57:54 -0700

Hi,

I'm still battling this one and am yet unsure whether this is a bug or not.  It would be great if someone could put me out of my misery  and confirm whether this is bug or not?

With the latest testing to characterise the problem it seems to be something to do with (a) controllers a sub-directory down &/or (b) url_for usage in a layout perhaps.  That is in the sense that I have a "url_for" which resolves find when the context is one controller but throws an error when in the context of another. 

Key points include:
  1. routes.rb routes a URL to a controller which is down 1 subdirectory - Example
      map.connect ':locale/mygoodness', :controller => 'highlevel/midlevel', :action ="" 'testaction', :defaults => {:locale => nil}
      map.connect ':locale/contactbackdoor', :controller => "contacts", :defaults => {:locale => nil}
  2. controller picks this up ok
    class Highlevel::MidlevelController < ApplicationController
      def testaction
        puts "Highlevel::MidlevelController - testaction"
      end
    end
  3. the "views/highlevel/midlevel/testaction.rhtml" view is small as the application.rb has a layout "site_layout" line.
  4. The "site_layout" has
             <%= link_to "2-contacts ", :controller => 'contacts' %>
  5. The site_layout link is generator OK when it is used from the opening page, BUT when it is utilised after a URL has come in via the controller which is down a sub-directory ( i.e. 'highlevel/midlevel) an error is encountered.  See below.
    1. Note the hash indicated in the error below has ":controller=>" highlevel/contacts" and it has seemed to munge the "highlevel/midlevel" controller name with the "contacts" controller name.
    2. Interestingly if I change the "url_for" line in the layout to: 

      •  <%= link_to "2-contacts ", :controller => nil %> one sees the following in the error :controller=>" highlevel/highlevel/midlevel"

      • <%= link_to "2-contacts ", :controller => "" %> one sees the following in the error
        :controller=>"highlevel/"
===============================================

ActionController::RoutingError in Highlevel/midlevel#testaction

Showing app/views/layouts/site_layout.rhtml where line #15 raised: 

No url can be generated for the hash {:action="" :controller=>"highlevel/contacts"}
