The validates_numericality_of method in ActiveRecord specifically sends (activerecord/lib/active_record/validations.rb:1019, in rails-2.3.5):
record.send("#{attr_name}_before_type_cast")
While this method exists for any native-columns in ActiveRecord, it doesn't with the virtual non-encrypted fields.
Example:
class AchPayment < ActiveRecord::Base
attr_encrypted :account_number, :key => $encryption_key
attr_encrypted :routing_number, :key => $encryption_key
validates_length_of :account_number, :in => 2..15
validates_numericality_of :account_number, :only_integer => true
validates_length_of :routing_number, :is => 9
validates_numericality_of :account_number, :only_integer => true
end
Produces:
a = Factory.build(:ach_payment)
=> #
a.save
NoMethodError: undefined method `account_number_before_type_cast' for #<AchPayment:0x102e380c0>

would it make sense to add a _before_type_cast match to Huberry::AttrEncrypted::Adapters::ActiveRecord::method_missing_with_attr_encrypted ?
