I have devise_invitable gem and an invitations controller InvitationsController < Devise::InvitationsController. I invite my user with this method User.invite!(user, inviter) from the gem.
Now, I would like to add pdf attachment to this invitation but I am not able to override the mailer method in order to do stuff like this: attachments['terms.pdf'] = File.read('/path/terms.pdf').
My invitation email is working fine and I would like to keep it like that but with an attachment.
Here my routes.rb:
devise_for :users, controllers: { invitations: 'api/v1/users/invitations' }
What am I missing?
Thanks 🙏
DeviseInvitable has a usefull skip_invitation option.
With the following method you can easily use your own mailer and add attachment in it :
def invite_and_notify_user(email)
user = User.invite!({ email: email }) do |u|
u.skip_invitation = true
end
notify_by_email(user)
end
def notify_by_email(user)
MyUserMailer.invited_user_email(user).deliver
end
In MyUserMailer class:
def invited_user_email(user)
@user = user
attachments['terms.pdf'] = File.read('/path/terms.pdf')
mail(to: user.email, from: 'contact@mail.com', subject: "Your subject")
end
You can override the devise mailer like so...
class MyMailer < 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 your mailer uses the devise views
# If there is an object in your application that returns a contact email, you can use it as follows
# Note that Devise passes a Devise::Mailer object to your proc, hence the parameter throwaway (*).
default from: ->(*) { Class.instance.email_address }
end
You can then in your config/initializers/devise.rb, set config.mailer to "MyMailer". Note that this overrides the mailer used for all devise modules.
Then in that class add your attachment to invited_user_instructions...
def invited_user_instructions(*args)
attachments['terms.pdf'] = File.read('/path/terms/pdf')
super
end
