Module: Devise::Models::Confirmable

Extended by:
ActiveSupport::Concern
Includes:
ActionView::Helpers::DateHelper
Defined in:
lib/devise/models/confirmable.rb

Overview

Confirmable is responsible to verify if an account is already confirmed to sign in, and to send emails with confirmation instructions. Confirmation instructions are sent to the user email after creating a record and when manually requested by a new confirmation instruction request.

Options

Confirmable adds the following options to devise_for:

* +allow_unconfirmed_access_for+: the time you want to allow the user to access his account
  before confirming it. After this period, the user access is denied. You can
  use this to let your user access some features of your application without
  confirming the account, but blocking it after a certain period (ie 7 days).
  By default allow_unconfirmed_access_for is zero, it means users always have to confirm to sign in.
* +reconfirmable+: requires any email changes to be confirmed (exactly the same way as
  initial account confirmation) to be applied. Requires additional unconfirmed_email
  db field to be setup (t.reconfirmable in migrations). Until confirmed new email is
  stored in unconfirmed email column, and copied to email column on successful
  confirmation.
* +confirm_within+: the time before a sent confirmation token becomes invalid.
  You can use this to force the user to confirm within a set period of time.

Examples

User.find(1).confirm!      # returns true unless it's already confirmed
User.find(1).confirmed?    # true/false
User.find(1).send_confirmation_instructions # manually send instructions

#active_for_authentication?Boolean

Returns:

  • (Boolean)
