Hi,
I''ve got troubles overriding some Rails generated URL helpers...
My site allows registered users to create some kind of diagrams online,
and then to browse all created diagrams, etc.
I''ve got a route to access a diagram created by a user:
map.diagram '':owner_id/:id'', :controller =>
''diagrams'', :action =>
''show''
When I want to have a link or redirect to a diagram, I''m currently
doing
this:
redirect_to diagram_path(diagram.owner, diagram) -- so that :owner_id
and :id are correctly set
I want to do something so that diagram_path(diagram) would generate the
correct URL with diagram''s owner id and diagram''s id.
What I have tried to do is to rename my route:
map.full_diagram '':owner_id/:id'', :controller =>
''diagrams'', :action =>
''show''
and then in DiagramsHelper, to override diagram_path and diagram_url
like this:
def diagram_path(diagram, *args)
full_diagram_path(diagram.owner, diagram, *args)
end
It''s working well, except for one thing: the method is not available in
my controllers. Though I''ve got "helpers :all" in
ApplicationController.
So, in a view, diagram_path(diagram) would give "/olance/27", whereas
a
redirect_to diagram_path(diagram) in a controller would redirect to
"/diagrams/27".
If I copy my overriden methods in application_controller.rb, then it
does work. So I really don''t get it, why would my helpers not be
included?
Is there a better way to do what I''m trying to achieve? I might have
missed something in the routes mechanisms... nested routes maybe?
I''m using Rails 2.3.8 by the way.
Thanks a lot,
Olivier

I''ll certainly try going this way... however, do you have any idea about this overriding thing? I''d like to understand why my views can use my overriden methods but not my controllers... :\ -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Not sure whats up in your case but you can do a quick google search for rails using helpers in controllers -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Helpers are made for views indeed, but who''s ever been doing a controller without any URL helper? That''s maybe why my overridden ones aren''t in my controllers, maybe they''re not Helpers as other view helpers? I''ll try to figure that out... Another thing now... I''m using acts_as_commentable and I have a comments controller that can create a comment and associate it to any commendable model. I''m using polymorphic_path to redirect to the model show page once the comment is added. How can I still do this with a nested route, which will require owner plus model''s id, when any other model pah would just require the model''s id?! (that''s why I came to the override at first) Thanks again!
