Ruby on Rails

Interesting... was not aware of this. Just today was writing a helper method to create a friendly id for an object I am writing to a table row. The challenge with dom_id/class is that when using Cucumber you really do not know (without making a good guess) what the id of a record will be.

I am curious if anyone has done or thought of the following for models, something where one defines what fields would constitute a friendly field id which does not involve the index but fields that would be known in a Cucumber scenario? I seem to be writing helpers for this quite often as it seems like often the best strategy for checking for something on a page is to place the data with an id or as a child of some object with a specific id or class. I am not quite sure how to do this as it seems it would have to extend ActiveModel/ActiveRecord...or maybe be done in a module which can be aware of what constituted the friendly_id of a model:

include FriendlyId
class Borrower < ActiveRecord::Base
  friendly_id :last_name, :first_name # so in each model you just define what fields of the model will constitute the friendly id
end

module FriendlyId
  def friendly_id
     # how do I access the 'friendly_id' settings from the model I am mixed in to?
  end
end

borrower = Borrower.new(:last_name => "Kahn", :first_name => "David) # using ActiveRecord/ActiveModel



borrower.friendly_id
>> "kahn_david"

or

friendly_id(borrower)



David
