gov_uk_date_field in non-ActiveRecord class

[lostie]

I'm trying to use this helper in a form class which is not particularly tied to an ActiveRecord class and I'm getting the following error:

NoMethodError - undefined method `after_initialize' for Forms::Search:Class:
   () Users/username/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/bundler/gems/gov_uk_date_fields-8694009d8e08/lib/gov_uk_date_fields/acts_as_gov_uk_date.rb:17:in `acts_as_gov_uk_date'

Is it possible to provide support for this helper outside the scope of an ActiveRecord?

PVB team also need to use this with non ActiveRecord::Base model

I'm a bit late to the party but for a Family Justice project I've made this gem works with non-AR models. In case it is useful this is the specific PR implementing a date field in a non-AR object:

ministryofjustice/c100-application#23

The main reason why it was not working is because non-AR models doesn't implement callbacks out of the box. But you can extend your model to use callbacks.

Also, so the gem works out of the box, the methods [] and []= must be re-implemented in your model. This is because the gem uses in a couple places this syntax to have direct access to attributes bypassing getter/setter. Ideally the gem shouldn't rely on these methods so it is less coupled to AR.
