Module: Devise::Models::Recoverable

Extended by:
ActiveSupport::Concern
Defined in:
lib/devise/models/recoverable.rb

Overview

Recoverable takes care of resetting the user password and send reset instructions.

Options

Recoverable adds the following options to devise_for:

* +reset_password_keys+: the keys you want to use when recovering the password for an account
* +reset_password_within+: the time period within which the password must be reset or the token expires.
* +sign_in_after_reset_password+: whether or not to sign in the user automatically after a password reset.

Examples

# resets the user password and save the record, true if valid passwords are given, otherwise false
User.find(1).reset_password('password123', 'password123')

# creates a new token and send it with instructions about how to reset the password
User.find(1).send_reset_password_instructions

def reset_password(new_password, new_password_confirmation)
  if new_password.present?
    self.password = new_password
    self.password_confirmation = new_password_confirmation
    save
  else
    errors.add(:password, :blank)
    false
  end
end

#reset_password_period_valid? ⇒ Boolean

Checks if the reset password token sent is within the limit time. We do this by calculating if the difference between today and the sending date does not exceed the confirm in time configured. Returns true if the resource is not responding to reset_password_sent_at at all. reset_password_within is a model configuration, must always be an integer value.

Example:

# reset_password_within = 1.day and reset_password_sent_at = today
reset_password_period_valid?   # returns true

# reset_password_within = 5.days and reset_password_sent_at = 4.days.ago
reset_password_period_valid?   # returns true

# reset_password_within = 5.days and reset_password_sent_at = 5.days.ago
reset_password_period_valid?   # returns false

# reset_password_within = 0.days
reset_password_period_valid?   # will always return false

Returns:

  • (Boolean)
