Hi,
Q1: The goal is to return the current object with 'self'.
When, you try in irb => 'a' && 'b', Ruby returns you 'b', because is the last non nil object but when the password comparaison failed, it the comparaison value which is returned, thus 'false'.
Q2: According to my interpretation, there is none validations on the current object.
Best regards.

has_secure_password has a method authenticate to authenticate users
using bcrypt. In secure_password.rb file I found the following lines
(from github):
def authenticate(unencrypted_password)
BCrypt::Password.new(password_digest) == unencrypted_password &&
self
end
BCrypt::Password.new(password_digest) == unencrypted_password is clear.
Q1: Can anyone explain why the result of
BCrypt::Password.new(password_digest) == unencrypted_password is ANDed
with 'self'?
Q2: Since authenticate becomes an instance method of a class, for
instance,User and so an instance method of, say, object user, self must
be equal to (the current object) `user'. Am I right?
