Overriding path helpers in Rails using define_method

I need to override quite a few path helper methods in Ruby on Rails and call super from them. My standard approach would be:
path_helper.rb

def business_path(business)  if params[:city_id] == 2    moscow_business_path(business)  else    super  endend

But I have a lot of these methods, so I want to define them dynamically like this:

  %i[root businesses business ...].each do |path_method|    method_name = "#{path_method}_path"    old_method = method(method_name)    define_method(method_name) do |*args|      if params[:city_id] == 2        public_send("moscow_#{method_name}")      else        old_method.call(*args)      end    end  end

But I get this error:

 /home/leemour/Ruby/burobiz/app/helpers/path_helper.rb:31:in `method': undefined method `root_path' for class `Module' (NameError)  from /home/leemour/Ruby/burobiz/app/helpers/path_helper.rb:31:in `block in <module:PathHelper>' from /home/leemour/Ruby/burobiz/app/helpers/path_helper.rb:29:in `each' from /home/leemour/Ruby/burobiz/app/helpers/path_helper.rb:29:in `<module:PathHelper>' from /home/leemour/Ruby/burobiz/app/helpers/path_helper.rb:1:in `<top (required)>' from /home/leemour/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/activesupport-5.1.3/lib/active_support/dependencies.rb:476:in `load'

I guess helper modules haven't been included yet, so there is no original path helper method to capture with method(method_name). Then I guess I'd have to use self.included hook but I couldn't figure it. How can I adjust this code to make it work? (I don't want to use eval).
