With the route generated by the Vanity gem, what is the Rails route helper I can use?

问题

This is the route the Vanity gem generates:

controller :vanities do 
  match ':vname' => :show, :via => :get, :constraints => {:vname => /[A-Za-z0-9\-\+]+/}
end

This is the rake routes:

GET    /:vname(.:format)                       {:vname=>/[A-Za-z0-9\-\+]+/, :controller=>"vanities", :action=>"show"}

How do I use the Rails link helper to link directly to URL mydomain.com/vname?

回答1:

From the top of my head (sorry, I don't really have the time to test it right now):

controller :vanities do 
  match ':vname' => :show, :via => :get, :constraints => {:vname => /[A-Za-z0-9\-\+]+/}, :as => :vanity
end

which you would use like this:

vanity_path(:vname => "marcamillion")
