Rails - Nov 2006 - inferred_routes plugin

Hi --

I''ve written a little plugin -- consisting entirely of modifications
to define_url_helper in ActionController -- which will infer nested
named RESTful route components from one object.

For example, given a nest like this:

   map.resources :schools do |s|
     s.resources :departments do |d|
       d.resources :teachers
     end
   end

instead of doing this:

   teacher_url(@school, @department, @teacher)

the plugin lets you do:

   teacher_url(@teacher)

and it infers that you really want:

   teacher_url(@teacher.department.school, @teacher.department, @teacher)

It''s very much a "see if people like it" kind of thing.  So
let me
know.

You can get it via subversion from:

I''ve made it a little less hackerly by putting the code in lib/ rather
than in init.rb :-)  Nothing else has changed, but if you want to have
a version that''s a bit more well-behaved in its code organization, you
can get:

David,

one more question before you put your sword to rest : what about
polymorphic associations?

   map.resources :articles do |article|
      article.resources :comments
   end
   map.resources :photos do |photo|
      photo.resources :comments
   end

In this case,
    comments_url(@comment)
should translate to something like
    comments_url(@comment.commentable_id, @comment)
(?? and what about the ''commentable_type)

I must confess I''m a REST newbie, so I''m not sure at all REST
can work
with polymorphism.
