Hey, I''m trying to specify validations with ActiveModel::Validations at the module level, i.e., I wish to mix-in validations to a module. I am not succeeding at this, however. How do I mix-in ActiveModel::Validations into another module and use its methods just as I would in a class?

Frederick,
I seek to create Ruby modules that use ActiveModel::Validations. The
examples I have seen of ActiveModel::Validations all involve including
that module in classes. This is not what I want. I want to involve the
use of ActiveModel::Validations in a module, which I may then choose to
implement as a ruby class (even if after a few more descents via other
modules.)
In short, how do I do get to do the following (or its equivalent) in a
module?
validates :some_attribute, :numericality_of=>{:greater_than => 0,
:allow_blank=>true}

Matt, Thanks, that did the trick, and I think it unlikely that I would have found that without some help! Now, on to what is likely the subject of yet another post: How do I obtain the effect of ActiveModel::Validations#validates_associated if applied to non-ActiveRecord classes where I seek to obtain nested validations when the given class is composed of multiple Ruby objects...
