multiple routes file rails 5 - ruby-on-rails

Question

I have the following code
application.rb
config.autoload_paths += %W(#{config.root}/config/routes)
routes.rb
Rails.application.routes.draw do
root to: 'summary#index'
extend General
end
/config/routes/general.rb
module General
def self.extended(router)
router.instance_exec do
# devise routes
devise_for :users, controllers: { sessions: 'users/sessions' }
end
end
end
I get uninitialized constant General when loading the app.
I''m using Ruby 2.2.6 and Rails 5.0.2

Answer 1

in rails 6, you can use draw(:general), which will look for route definition in config/routes/general.rb
You can emulate this with an initializer:
module RoutesSubfolder
# Extension to Rails routes mapper to provide the ability to draw routes
# present in a subfolder
#
# Another solution would be to add the files to `config.paths['config/routes']`
# but this solution guarantees the routes order
#
# Example: <config/routes.rb>
#
# Rails.application.routes.draw do
# # this will eval the file config/routes/api.rb
# draw :api
#
# Example:
# draw :'api/whatever' # loads config/routes/api/whatever.rb
#
def draw(name)
path = Rails.root.join('config', 'routes', "#{name}.rb")
unless File.exist?(path)
raise StandardError, "Unable to draw routes from non-existing file #{path}"
end
instance_eval(File.read(path), path.to_s, 1)
end
end
ActionDispatch::Routing::Mapper.prepend(RoutesSubfolder)
The only difference with what you proposed is that:
you don't need to change the autoload_path
in general.rb, you directly declare your routes the same way you'd do in config/routes.rb inside the Rails.application.routes.draw do block
