# DeviseEmailValidator
|
|
#
|
|
# Custom validator for email formats. It asserts that there are no
|
|
# @ symbols or whitespaces in either the localpart or the domain, and that
|
|
# there is a single @ symbol separating the localpart and the domain.
|
|
#
|
|
# The available options are:
|
|
# - regexp: Email regular expression used to validate email formats as instance of Regexp class.
|
|
# If provided value has different type then a new Rexexp class instance is created using the value.
|
|
# Default: +Devise.email_regexp+
|
|
#
|
|
# Example:
|
|
# class User < ActiveRecord::Base
|
|
# validates :personal_email, devise_email: true
|
|
#
|
|
# validates :public_email, devise_email: { regexp: Devise.email_regexp }
|
|
# end
