activemodel (support for other mappers like mongoid)?

[sanford]

Seems like this would be a great addition to activemodel for Rails3 so it could be used across other database mappers (mongoid, mongo_mapper, datamapper).

I'd love to use it with mongoid right now. How easy would a port be?

I think you can use it right away. One way is to use auto_html method that is available in any object that includes AutoHtml module. You'd only have to implement before_save if you want to cache result.

Other (not sure if it will work) is to include AutoHtmlFor module (if you want auto_html_for method) in non AR model which uses only before_save callback and read/write attribute methods so I guess it should work with mongoid.

Please let me know of the result if you try that out.

Currently auto_html has activerecord as runtime dependancy.
I have fixed this here.

Working mongoid example:

class Post
  include Mongoid::Document
  include AutoHtmlFor

  field :body

  auto_html_for :body do
    link
  end
end

Thanks! I've included the fix, and added your example to readme.

Great! In the readme you should change the title from "Non-ActiveModel models" to "Non-ActiveRecord models"

Good catch, thanks.
