# Validatable creates all needed validations for a user email and password.
|
|
# It's optional, given you may want to create the validations by yourself.
|
|
# Automatically validate if the email is present, unique and its format is
|
|
# valid. Also tests presence of password, confirmation and length.
|
|
#
|
|
# == Options
|
|
#
|
|
# Validatable adds the following options to devise_for:
|
|
#
|
|
# * +email_regexp+: the regular expression used to validate e-mails;
|
|
# * +password_length+: a range expressing password length. Defaults to 6..128.
|
|
#
|
|
module Validatable
|
|
# All validations used by this module.
