[ANN] Validation Reflection plugin

The validation reflection plugin adds three things

(1) Reflective access to validations
- ModelClass.reflect_on_all_validations
- ModelClass.reflect_on_validations_for(:property)

(2) It provides “declarative” methods for defining
validations based on database metadata
- validates_presence_of_mandatory_content_columns
- validates_lengths_of_string_attributes
- validates_all_associated

(3) It reflects validation information into the class attributes of
of HTML elements generated from rhtml templates.
See test/instance_tag_validations_test.rb for what this looks like.
Yes, for validates_format_of it gets nasty.

Great work Micheal.

Thanks. I had the functionality lying around for more than a year as
part of my BoilerPlate project. But as that project is all but dead, I
intend to release some of its reusable functionality in the form of
plugins.

If you want to use this for client-side validation, have a look at my
almost purely declarative validator at

It is, unfortunately, based on an earlier version of Prototype and my
own support code probably clashes with current the Prototype lib. I
intend to rectify this some time and bundle the stuff in a plugin.
Alas, I don’t have the time right now to do it right.
