Hey guys. In Rails 2, is there a way to create a route at run-time? I
want to do this because a gem that I’m writing requires a single
resource route, and I’d prefer that the gem create it at run-time
instead of forcing the user to define the route in routes.rb .
While trying to figure this out, I discovered that calling
ActionController::Routing::Routes.draw do |map|
# my gem’s route here
end
causes all of the routes in routes.rb to be removed.
I tried copying the routes from ActionController::Routing::Routes into
a new array or hash, then rebuilding them and adding my gem’s route,
but couldn’t get that to work. Also, it’s messy and less than ideal.

If you have a plugin with a structure that looks like
my_plugin/
app/
controllers/
…
config/
routes.rb
lib/
…
Then rails will add the routes from that routes.rb file. (Don’t know
if you have to have app/controllers, i’ve just always wanted to add a
route to a controller that was also in the plugin).
Since plugins can be packaged as gems, some variation on the above
should work

Interesting! I didn’t that you could do that. Unfortunatey, I couldn’t
get it to work.
$cat config/routes.rb
ActionController::Routing::Routes.draw do |map|
map.resource :dashboard, :only => :show
map.connect “dashboard/widgets/path", :controller
=> :dashboards, :action => ‘widget_data’
end
$
$ cat vendor/gems/acts_as_dashboard-0.0.0/config/routes.rb
puts "**** #{FILE}”
ActionController::Routing::Routes.draw do |map|
map.connect ‘foo/*path’, :controller => :dashboards
end
$
$ rake routes
(in /home/nick/src/acts_as_dashboard_container)
dashboard GET /dashboard(.:format)
{:action=>“show”, :controller=>“dashboards”}
/dashboard/widgets/:path
{:action=>“widget_data”, :controller=>“dashboards”}
$
Any idea why the gem’s routes.rb isn’t being processed?
“Another big change is that Rails now supports multiple routing files,
not just routes.rb. You can use RouteSet#add_configuration_file to
bring in more routes at any time – without clearing the currently-
loaded routes.”
I just found Section 5.4 inhttp://guides.rubyonrails.org/2_3_release_notes.html
:
“Another big change is that Rails now supports multiple routing files,
not just routes.rb. You can use RouteSet#add_configuration_file to
bring in more routes at any time – without clearing the currently-
loaded routes.”
I’ll check this out tonight!
In addition to
ActionController::Routing::RouteSet#add_configuration_file , there’s
also #add_named_route , and simply #add_route . How convenient!
