Validation documentation error
Reported by Daniel | July 7th, 2009 @ 05:46 PM
Hello Ben,
It seems that there is a discrepancy between the below two documentation pages in that one creates a "before_validation" callback, while the other creates a "validate" callback. In any case, I'm not having success with either version. When using "before_validation", "attempted_record" is nil. When using "validate", my method does not get called at all.

http://rdoc.info/rdoc/binarylogic/authlogic/blob/aa4ee71622b151f3a2...
In the below example, nothing gets printed. Changing "validate"
to "before_validation" prints the $s, but then throws a "nil
object" error when reaching "if attempted_record.invited?" ("The
error occurred while evaluating nil.invited?").
class UserSession < Authlogic::Session::Base
logout_on_timeout true
consecutive_failed_logins_limit 12
validate :ensure_not_invited
private
def ensure_not_invited
puts "$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$"
if attempted_record.invited?
puts "********************************************"
self.errors.clear
self.errors.add_to_base('invited_but_not_created')
end
end end

After updating AuthLogic to version 2.1.1 from 2.0.14, validate :ensure_not_invited now causes ensure_not_invited to be called, but attempted_record is still nil.

You are right, but attempted_record could have the possibility of being nil. Checkout this code:
def valid? errors.clear self.attempted_record = nil before_validation new_session? ? before_validation_on_create : before_validation_on_update validate ensure_authentication_attempted if errors.size == 0 new_session? ? after_validation_on_create : after_validation_on_update after_validation end save_record(attempted_record) errors.size == 0 end private def ensure_authentication_attempted errors.add(:base, I18n.t('error_messages.no_authentication_details', :default => "You did not provide any details for authentication.")) if errors.empty? && attempted_record.nil? endThe validation chain will continue to be called regardless if attempted record is found or not. So if attempted_record is nil, that means the credentials passed could not locate a record. In your method you should check to see if attempted record is present before doing anything with it. If it is not present, there will be errors in the errors object.
Validations have to occur this way for the magic fields and brute force protection. Ex: failed_logins_count.
Hope that wasn't too confusing.

Thanks Ben. I was using valid login data, but perhaps because the object wasn't confirmed, the attempted_record stayed at nil. I was hoping to supersede the unconfirmed error with a different error, but at this point, I'm refactoring away from that need anyway, so it is no longer a problem for me.
Cheers,
Daniel

The documentation error is very common nowadays. It's only because of the lack of knowledge in the initiation procedures. I went through the description and i have followed it. I am glad that it works well. Thanks for the share. online computer repair

Active Record offers many pre-defined validation helpers that you can use directly inside your class definitions. These helpers provide common validation rules. Every time a validation fails, an error message is added to the object's errors collection, and this message is associated with the attribute being validated krogerfeedback.
