#url(env, *args) ⇒ Object

Generates a url from Rack env and identifiers or significant keys.

To generate a url by named route, pass the name in as a Symbol.

url(env, :dashboard) # => "/dashboard"

Additional parameters can be passed in as a hash

url(env, :people, :id => "1") # => "/people/1"

If no name route is given, it will fall back to a slower generation search.

url(env, :controller => "people", :action => "show", :id => "1")
  # => "/people/1"
