How to change “Devise: password reset instruction email's subject”

Question

I\'m just unable to change \"password reset instruction\" email\'s subject. I have changed notifer.rb in Mailer to overwrite Devise default email subject. But it\'s not work

Answer 1

If you're willing to translate your Devise messages, which was my case, a better practice would be creating a new yml file in config/locale and changing your application's locale at config/application.rb

1. To illustrate, I had to create devise.pt-BR.yml inside config/locale.

2. Then I copied its translations from internet, on this link.

3. Finally, I set my application's new locale at config/application.rb as follows:

   config.i18n.default_locale = :'pt-BR'
   

Hope it helps some of you guys having the same problem as mine.

Answer 2

I got this to work by creating my own sub-class of Devise::Mailer.

class DeviseMailer < Devise::Mailer
  def reset_password_instructions(record, token, opts={})
    mail = super
    # your custom logic
    mail.subject = "[SOME DB DATA]"
    mail
  end
end

And then modifying the devise.rb initializer to use my mailer.

# Configure the class responsible to send e-mails.
config.mailer = 'DeviseMailer'

For default foreign language (example Japanese)

STEP 1 Create a 'ja.yml' in config/locales/ (or whatever filename)

ja:
  devise:    
    mailer:
      confirmation_instructions:
        subject: '仮会員登録完了のお知らせ'
      reset_password_instructions:
        subject: 'パスワード再設定手順のお知らせ'

STEP 2 On config/environments/development.rb

config.i18n.default_locale = :ja

STEP 3 Restart server

Answer 4

Change option :subject:

class DeviseMailer < Devise::Mailer
  def reset_password_instructions(record, token, opts={})
    opts[:subject] = 'SOME DB DATA'
    super
  end
end

Answer 5

You can write your own method inside your controller and call the respective mailer template. This will help you.. Else devise views, there will be a view page to send reset instruction. Change the content there..

Answer 6

you can change it in devise.en.yml file in intilizer directory

And set your own subject for any mailer

                   mailer:
                     confirmation_instructions:
                       subject: 'Confirmation instructions'
                     reset_password_instructions:
                       subject: 'Reset password instructions'
                     unlock_instructions:
                       subject: 'Unlock Instructions'
