I''m trying to add paging parameters to link_to inside an
application_helper method.
def index_show_link(elm, link_text = ''Show'')
(can?(:read, elm)) ? link_to( link_text, elm ) :
'' ''.html_safe
end
I want to add the :page => params[:page] pair into the link, but I
can''t seem to find a way to add it. If I use the long-hand syntax: {:id
=> elm.id, :controller => controller_name, :action => :show, :page
=> params[:page]} then it works, but that also horses around with
friendly_id.
I''ve looked through the link_to and url_for documentation, and I
can''t see a way to pass the bare object to either method and also
include the extra parameter.
What''s the trick?
Thanks,
Walter

If I use the long-hand syntax: {:id => elm.id, :controller => controller_name, :action => :show, :page => params[:page]} then it works, but that also horses around with friendly_id.I found that substituting to_param for id makes FriendlyId work correctly again, and this one is solved. Still seems awfully long-hand. Walter -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That''s a new one on me.

Thanks!polymorphic_path is a rails provided method - it''s what gets called by rails when you shorthand stuff like form_for(some_object) or link_to ''blah'', some_other_object. It basically just looks at the class name (probably via the activemodel::naming) stuff and then calls the explicit path helper (comment_path etc) that it expects to exist given what you''re asking it to do.
