Ah!
I just overrode DM::V::ValidationErrors.default_error_messages
somewhere after the gem is loaded, but before models are. In Rails 3,
this means creating an initializer and placing http://gist.github.com/447681
in it. Total monkey patch, but it works.
As for custom validation, you'd most likely want to create a validator
class that inherits from DM::V::GenericValidator. The catch with:
if u.valid?
u.errors.add(:name, 'Invalid name')
puts "Valid: #{u.valid?}"
end
is that calling #valid? actually clears all errors, then reruns all
validators for that resource.
However, if you only want to override the default validation error
messages, might I suggest another ugly hack: http://gist.github.com/447683
.

Yeah, i saw the default messages, but i dont really want to change
original gem.
Also, i noticed that custom validation errors does not work.
Example:
class User
include DataMapper::Resource
property :id, Serial
property :name, String
property :email, String, :length => 6..64, :format
=> :email_address
end
u = User.new(:name => 'My name', :email => '[email protected]')
if u.valid?
u.errors.add(:name, 'Invalid name')
puts "Valid: #{u.valid?}"
end
Or maybe im just doing it wrong. Ideas?

AFAIK, there isn't an option to disable column names from being
included.
Instead, I do what you describe: change the default validation
messages
(DataMapper::Validations::ValidationErrors.default_error_messages=).
Unfortunately, this also means I had to monkey-patch
DM::V::VE.default_error_message so that it doesn't interpolate the
field name.

Oh, and i forgot to add, this can be done with custom validation
messages.
But the question still the same: is it possible to make this
conversions automatically?
