My two methods using Devise:
Method1
def self.find_first_by_auth_conditions(warden_conditions) conditions = warden_conditions.dup wh
2.. I guess you mean that signin is not defined in find_first_by_auth_conditions? Then I also guess that signin is an attribute of warden_conditions so you can try: warden_conditions.signin.
signin
find_first_by_auth_conditions
warden_conditions
warden_conditions.signin
