lazy_model
More documentation to come. Check the tests to see all the permutations.
If you have boolean attributes on a model or a text/string attribute and a set list of values (think enumerable), then you can get several finders & instance methods for free. For instance:
Examples
class Post < ActiveRecord::Base
CHOICES = [“one”, “two”, “three”]
lazy_model :archived #boolean lazy_model :choice, Post::CHOICES, => [“one”, “three”] #string
end
Post.prime.archived #composable query where choice is in “one”, “two” and archived is true
Post.one.nil_archived #composable query where choice is equal to “one” and archived is nil
Post.not_two.not_archived # composable query where choice is not equal to two and archived is false
Post.choice # composable query of all posts where choice is not nill
post = Post.new
post.one? #true if post.choice == “one” post.prime? #true if [“one”, “three”].include?(post.choice)
Restrictions
This is a ActiveRecord 3.x party.
Notes
The next simple addition is to add date support.
Even cooler would be to add some support for intellegent association methods. I’d love to get some feedback on this. What would that api look like?

Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
