merb router weird behavior.rb

resources :companies do
  collection :do_something, :method => :post

#
# You might notice that 2 routes have the same index (3)
#

# in router.rb, method route_for:
# You have this line:

route = routes[index] if index


#
# So, if you go to /companies/1
# You will find that:

request.route
=> /companies/do_something(.:format)

# Isn't that weird?
#
# Shouldn't it be: /companies/:id(.:format) ?
#
# Maybe I shouldn't use request.route (private) but I thought I should still mention it
