Question

With a standard map.resource routing mechanics and several nested resources the resultant routes are unnecessarily long. Consider the following route:

site.org/users/pavelshved/blogs/blogging-horror/posts/12345

It s easy to create in routes.rb, and I m sure it follows some kind of beneficial routing logic. But it s way too long and also seems like it s not intended to be human-readable.

A nice improvement would be to drop controller names, so it looks like:

site.org/pavelshved/blogging-horror/12345

Clear, simple, short. It may become ambiguous, but in my case I m not going to name any user "users", for instance.

I tried setting :as => , but it yields routes like this: site.org//pavelshved//blogging-horror//12345 when generating them by standard helpers.

Is there a way to map resources in such a way, that controller names become optional?

Answer 1

You re looking for the :path_prefix option for resources.

map.resources :users do |user|
  user.resources :blogs do |blog|
    blog.resources :posts, :path_prefix =>  /:user_login/:blog_title/:id 
  end
end

Will produce restful routes for all blogs of this form: site.org/pavelshved/bogging-horror/posts/1234. You ll need to go to a little extra effort to use the url helpers but nothing a wrapper of your own couldn t quickly fix.

The only way to get rid of the posts part of the url is with named routes, but those require some duplication to make restful. And you ll run into the same problems when trying to use route helpers.

Answer 2

The simplest way to get what you want would be to create a route in addition to your RESTful routes that acts as a shorthand:

map.short_blog  :user_id/:blog_id/:id , :controller =>  posts , :action =>  show

You ll have to change the URL bits to work with how you re filtering the name of the user and the name of their blog. But then when you want to use the shorter URL you can use all the short_blog_* magic.

Answer 3

Straight out of the default routes.rb:

map.connect  products/:id , :controller =>  catalog , :action =>  view

You could write:

map.connect  :user_id/:blog_id/:id , :controller =>  posts , :action =>  show

But be sure to include that in the very end of the file, or it will try to match every three levels deep url to it.

Answer 4

Try this

map.pavelshved  /pavelshved/ , :controller => :users, :action => view or
map.pavelshved  /:id , :controller => :users, :action => show do | blogs|
  blogs.bloging  /:id , :controller => :blogs, :action => show do | post|
    post.posting  /:id , :controller => :posts, :action => show
  end
end

I hope it work :)

Google "rails shallow routes" for information about this.
