Replacing ActiveRecord::Validations with Validatable

Hello, I'm getting familiar with Validatable. I want to change all the ActiveRecord Validations in my applications to Valdatable. But I have a question, since ActiveRecord also handles associations how can use Validatable and keep working the models relationships.

Having an easy way to validate non-ActiveRecord objects would be awesome. The current hack I'm using is ugly as hell.

Using a third party library seems to make sense, as this is a common problem in a lot of Ruby code, and having a single place to put stuff is preferable -- ActiveRecord and ActiveModel could just extend the library with e.g. validates_association.

My ActiveModel implimentation can be found (https://github.com/rjspotter/rai..., "on github"). It works well enough for my purposes so far. I'm looking for others to give it a go and tell me if I'm smoking crack.

Hey guys,

My ActiveModel implementation is here: http://github.com/miloops/rails/...

I took out the tests of ActiveRecord, including i18n tests, of each validation and all tests are passing right now in ActiveModel.

At the moment 9 of 10 validations are working, all except uniqueness since is the most AR dependent by implementation.

Of course this is still experimental but in AR there are 102 tests, 109 assertions in validations and 126 tests, 732 assertions in i18n validations. My ActiveModel implementation is running and passing 117 tests with 602 assertions of those tests.

If anyone interested in what i'm doing please let me know.

Wow, three implementations! Sounds like miloops' is the most compatible and complete so far. Perhaps you guys could collaborate on this?

Here's my take on an ActiveModel implementation: http://github.com/leethal/active...

It is very lightweight. The validations part is pretty much done. It will break ActiveRecord miserably, of course. I think ActiveRecord itself should handle all the naughty backwards compability, so that ActiveModel itself can stay lean and clean.

I'll be working on making the AR tests pass with my code in the coming weeks.
