Add dynamic value in devise email subject - ruby-on-rails

Question

Ok I have seen many discussions about customizing devise email subject but none seems to solve what I want. Currently my confirmation email subject reads "Confirm your Qitch.com account". I want to customize this email subject and add a dynamic value of a user's name in it such that if user ALEX signs up for an account, he should get an email address with the subject, Welcome ALEX, confirm your Qitch.com account. How can I achieve this in devise?
devise.en.yml
mailer:
confirmation_instructions:
subject: 'Confirm your Qitch.com account'
reset_password_instructions:
subject: 'Reset your Qitch.com password'
unlock_instructions:
subject: 'Unlock your Qitch.com account'
Lastly, how do I add a name in the reply address or from address, currently when you receive the mail, it says sender: no-reply#qitch.com Is there a way I can customize it to Qitch
Thanks

Answer 1

I see that no answers are clean enough so I would like to make a short summary here.
First of all, you have to tell Devise you're going to override its origin mailer methods by:
config/initializers/devise.rb
config.mailer = 'MyOverriddenMailer'
After that, you need to create your overridden mailer class and override whatever method you want like this:
app/mailers/my_overridden_mailer.rb
class MyOverriddenMailer < Devise::Mailer
helper :application # gives access to all helpers defined within `application_helper`.
include Devise::Controllers::UrlHelpers # Optional. eg. `confirmation_url`
default template_path: 'devise/mailer' # to make sure that you mailer uses the devise views
def confirmation_instructions(record, token, opts={})
if record.name.present?
opts[:subject] = "Welcome #{record.name}, confirm your Qitch.com account"
else
opts[:subject] = "Confirm your Qitch.com account"
end
super
end
end
Remember to restart your Rails server to apply the changes! :)
Note:
List of opts options: subject, to, from, reply_to, template_path, template_name.
record is the instance of User model
And of course, origin document

Devise helper here and How To: Use custom mailer
class MyMailer < Devise::Mailer
def confirmation_instructions(record, opts={})
headers = {
:subject => "Welcome #{resource.name}, confirm your Qitch.com account"
}
super
end
def reset_password_instructions(record, opts={})
headers = {
:subject => "Welcome #{resource.name}, reset your Qitch.com password"
}
super
end
def unlock_instructions(record, opts={})
headers = {
:subject => "Welcome #{resource.name}, unlock your Qitch.com account"
}
super
end
end
Or
class MyMailer < Devise::Mailer
...
...
private
def headers_for(action)
if action == :confirmation_instructions
headers = {
:subject => "Welcome #{resource.name}, confirm your Qitch.com account"
}
elsif action == :reset_password_instructions
headers = {
:subject => "Welcome #{resource.name}, reset your Qitch.com password"
}
else
headers = {
:subject => "Welcome #{resource.name}, unlock your Qitch.com account"
}
end
end
end
And tell devise to use your mailer:
#config/initializers/devise.rb
config.mailer = "MyMailer"
NOTE : I haven't tried them yet, but they may be helpful and for anyone, please correction my answer, if there is an error you could edit my answer

I'm working with devise (3.2.1) and I've implemented the following solution, but to modify the from: field with localization:
# app/mailers/devise_mailer.rb
class DeviseMailer < Devise::Mailer
def confirmation_instructions(record, token, opts={})
custom_options(opts)
super
end
def reset_password_instructions(record, token, opts={})
custom_options(opts)
super
end
def unlock_instructions(record, token, opts={})
custom_options(opts)
super
end
private
def custom_options(opts)
opts[:from] = I18n.t('devise.mailer.from', name: Tenancy.current_tenancy.name, mail: ENV['FROM_MAILER'] )
end
end
Then I've defined the message in my locale files
# config/locales/devise.es.yml
es:
devise:
mailer:
from: "Portal de trabajo %{name} <%{mail}>"
To modify the subject, it should be almost the same:
def confirmation_instructions(record, token, opts={})
custom_options(opts, :confirmation_instructions)
super
end
private
def custom_options(opts, key)
opts[:from] = I18n.t('subject', scope: [:devise, :mailer, key])
end
# and in your locale file
es:
devise:
mailer:
confirmation_instructions:
subject: Instrucciones de confirmación

Answer 4

Hook in headers_for to e.g. prefix the subject for all devise mails.
# config/initializers/devise.rb
Devise.setup do |config|
# ...
config.mailer = 'DeviseMailer'
# ...
end
# app/mailers/devise_mailer.rb
class DeviseMailer < Devise::Mailer
def headers_for(action, opts)
super.merge!({ subject: 'Hi ALEX! ' + subject_for(action) })
end
end

Answer 5

Yo should create an ActionMailer like this one:
class Sender < ActionMailer::Base
default :from => "'Eventer' <dfghjk#gmail.com>"
def send_recover(user, pw)
mail(:to => user.email , :subject => "You have requested to change your password from Eventer") do |format|
format.text {
render :text =>"Dear #{user.name},
**Body**
Regards."
}
end
end
end
Then you should call it from the controller this way:
Sender.send_recover(#mail, current_user, #meetup).deliver
I hope it works for you!
