I'm following http://edgeguides.rubyonrails.org/plugins.html and at chapter 8, I'm told to add: ActionController::Routing::RouteSet::Mapper.send :include, Yaffle::Routing::MapperExtensions
In order to add the routes of my plugin in my Rails app...
Unfornately, ActionController::Routing is deprecated,
What should I use instead?
Thanks in advance,
