[patch] fix for multi-nested resources
Reported by humancopy | April 26th, 2009 @ 11:09 AM
hey ...
this patch fixes 2 bugs i found: when trying to use multi-nested resources & when the nested resource uses has_one or bleongs_to.
for example trying to access something like this: /categories/1/threads/2/posts
would throw out 2 exceptions:
- method not found for @thread.categories in specification.rb line # 74 (fixed using a respond_to? check first)
- Ardes::ResourcesController::ResourceMismatch in resources_controller.rb line # 738 (fixed by adding .reverse to the generated enclosing names array)
thanks :)
routing
# accessed /categories
map.resources :categories do |cat|
# accessed /categories/:category_id/threads
cat.resources :threads do |thrd|
# accessed /categories/:category_id/threads/:thread_id/posts
thrd.resources :posts
end
end
model associations
category.rb
has_many :threads
thread.rb
belongs_to :category
has_many :posts
post.rb
belongs_to :thread
controllers
categories_controller.rb
resources_controller_for :categories
threads_controller.rb
resources_controller_for :threads, :in => :category
posts_controller.rb
resources_controller_for :posts, :in => [:category, :threads]

well, this quick patch didn't work all the way through (hash being a hash) :)
then i found a better way, using recognized_route and it's significant_keys array, which is in the right order. if no recognized_route found it will revert to using params as before...
changing line # 738 in resources_controller to:
@route_enclosing_names = (recognized_route and recognized_route.significant_keys or params).select{|k| k.to_s =~ /_id$/}.map{|id| [id.to_s.sub('_id','').pluralize, false]}attached a patch. :)
