Best practices to handle routes for STI subclasses in rails

Question

My Rails views and controllers are littered with redirect_to, link_to, and form_for method calls. Sometimes link_to and <

Answer 1

The cleanest solution I found is to add the following to the base class:

def self.inherited(subclass)
  super

  def subclass.model_name
    super.tap do |name|
      route_key = base_class.name.underscore
      name.instance_variable_set(:@singular_route_key, route_key)
      name.instance_variable_set(:@route_key, route_key.pluralize)
    end
  end
end

It works for all subclasses and is much safer than overriding the entire model name object. By targeting only the route keys, we solve the routing problems without breaking I18n or risking any potential side effects caused by overriding the model name as defined by Rails.
