:action=\>“index”}  
POST /posts(.:format) {:controller=\>“posts”,  
:action=\>“create”}  
new\_post GET /posts/new(.:format){:controller=\>“posts”,  
:action=\>“new”}  
edit\_post GET /posts/:id/edit(.:format){:controller=\>“posts”,  
:action=\>“edit”}  
post GET /posts/:id(.:format){:controller=\>“posts”, :action=\>“show”}  
PUT /posts/:id(.:format){:controller=\>“posts”, :action=\>“update”}  
DELETE /posts/:id(.:format){:controller=\>“posts”, :action=\>“destroy”}  
post\_comments GET /posts/:post\_id/comments(.:format)  
{:controller=\>“comments”, :action=\>“index”} POST  
/posts/:post\_id/comments(.:format){:controller=\>“comments”,  
:action=\>“create”}  
new\_post\_comment GET  
/posts/:post\_id/comments/new(.:format){:controller=\>“comments”,  
:action=\>“new”}  
edit\_post\_comment GET /posts/:post\_id/comments/:id/edit(.:format)  
{:controller=\>“comments”, :action=\>“edit”}  
post\_comment GET /posts/:post\_id/comments/:id(.:format)  
{:controller=\>“comments”, :action=\>“show”}  
PUT /posts/:post\_id/comments/:id(.:format)  
{:controller=\>“comments”, :action=\>“update”}  
DELETE /posts/:post\_id/comments/:id(.:format)  
{:controller=\>“comments”, :action=\>“destroy”}
