Determine if path exists as route in Rails controller
12,766
Solution 1
SOLUTION:
@related_page_path = '/' + @page.path
begin
ActionController::Routing::Routes.recognize_path(@related_page_path, :method => :get)
rescue
@related_page_path = nil
end
Solution 2
For Rails 3 the call is
Rails.application.routes.recognize_path
Instead of
ActionController::Routing::Routes.recognize_path
Example:
def path_exists?(path)
Rails.application.routes.recognize_path(path)
true
rescue ActionController::RoutingError
false
end
Solution 3
If you want to connect an arbitrary path the a controller and and action, you can use map.connect
map.connect '/any/random/string/of/stuff', :controller => 'items', :action => 'new'
You can even call out embedded param designations in the path:
map.connect '/seeking/room/for/[:number_of_nights]/nights', :controller => 'rooms', :action => 'index'
with the above you will receive the value represented in the url as part of the params
hash in the controller.

I want to know if an arbitrary path can be mapped to a route
recognized_request_for accomplishes what I want, but I can't get it to work in my controller.
Specifically, how can I execute recognized_request_for or something that accomplishes the same task from my controller?
