Not use default route if you use RESTful design

Bad Smell

map.resources :posts, :member => { :push => :post }

map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'

Why do not use the default route? In this example, you define the resources posts, that means user can only create a post by HTTP POST, update a post by PUT and destroy a post by DELETE. If this is what you expect, default route will be a security problem, because user can create, update or destroy a post by HTTP GET if you define the default route.

Refactor

map.resources :posts, :member => { :push => :post }

#map.connect ':controller/:action/:id'
#map.connect ':controller/:action/:id.:format'

map.connect 'special/:action/:id', :controller => 'special'

Because default route is evil, just comment out or remove it (if you use RESTful)
