Best practices to handle routes for STI subclasses in rails

by

This is the simplest solution I was able to come up with with minimal side effect.

class Person < Contact
  def self.model_name
    Contact.model_name
  end
end

Now url_for @person will map to contact_path as expected.

How it works: URL helpers rely on YourModel.model_name to reflect upon the model and generate (amongst many things) singular/plural route keys. Here Person is basically saying I’m just like Contact dude, ask him.
