Encapsulates the pattern of wanting to validate a password or email address field with a confirmation.
1 2 3 4 5 6 7 8 9 10 | Model: class Person < ActiveRecord::Base validates_confirmation_of :user_name, :password validates_confirmation_of :email_address, message: 'should match confirmation' endView: <%= password_field "person", "password" %> <%= password_field "person", "password_confirmation" %> |
The added password_confirmation attribute is virtual; it
exists only as an in-memory attribute for validating the password. To
achieve this, the validation adds accessors to the model for the
confirmation attribute.
NOTE: This check is performed only if password_confirmation is
not nil. To require confirmation, make sure to add a presence
check for the confirmation attribute:
1 | validates_presence_of :password_confirmation, if: :password_changed? |
Configuration options:
-
:message- A custom error message (default is: âdoesn't match confirmationâ).
There is also a list of default options supported by every validator:
:if, :unless, :on,
:allow_nil, :allow_blank, and
:strict. See ActiveModel::Validation#validates
