Unfortunately Desert doesn't help us with overriding filters, validations
and associations. That means you can't just re-declare a validation in your
overriding model and expect it to work. Instead, you have to do an ugly
hack, something like:
class User < ActiveRecord::Base
after_validation :fix_errors
def fix_errors
self.errors.remove(:login) #remove all errors on login
unless self.login ~= /^[\s\.A-Za-z0-9_-]+$/ #(replace with whatever
regex you want)
errors.add(:login, "is invalid")
end
end
end
And also add an initialize in config/ar_remove_error.rb:
module ActiveRecord
class Errors
#removes all errors on the given attribute
def remove(attribute)
@errors.delete(attribute.to_s)
end
end
end
Please note that changing the regex for login validation may cause problems
in other parts of your app.
Thanks,
Bruno
