Is it possible to have a few passwords in authlogic gem? - ruby-on-rails

Question

Right now we have phone_number as login, and sms code (4 digits) as password.
When user wants to login:
- user enters phone number
- we generate code
- we save code to user password field
- we send code to user via sms
- user uses this sms code to login in
We want to be able to have last 3 generated codes (password) be valid for login:
- we started to save generated codes in separate table
And here is the question: How do I connect this to authlogic? Is the any callback that turns off default password check and give me ability to add my custom logic for password checking?

Answer 1

I found a solution which helped me to tune password validation logic.
My authlogic version 3.5.6 and I has method called validate_by_password in following implementation.
I copied first part of it to save blank fields and logic checks. And overwrote invalid password check in way I need.
class Client::Session < Authlogic::Session::Base
...
def validate_by_password
# copy paste from gem
self.invalid_password = false
# check for blank fields
errors.add(login_field, I18n.t('error_messages.login_blank', default: 'cannot be blank')) if send(login_field).blank?
errors.add(password_field, I18n.t('error_messages.password_blank', default: 'cannot be blank')) if send("protected_#{password_field}").blank?
return if errors.count > 0
# check for unknown login
self.attempted_record = search_for_record(find_by_login_method, send(login_field))
if attempted_record.blank?
generalize_credentials_error_messages? ?
add_general_credentials_error :
errors.add(login_field, I18n.t('error_messages.login_not_found', default: 'is not valid'))
return
end
# custom check for invalid password
...
end
end
