Ruby Forum Ruby on Rails > ActionMailer

Hi all,

I need a help. I have got a user registration form, where the user signs
up and then an activation link is sent to the user email id for
activating his/her account. Now I need to send an another email to the
user, only after he logs in for the first time in my site, then the
second email should be sent. Can anybody give me some suggestion on how
to do it ??


NB: When the user clicks on the activation link, he is not directed to
user home page, only the home page of my website is displayed.


Thanks
Saurav

In your controller where you check the activation link, mark the user
as activated, call a second ActionMailer, and then redirect.

In the following example the user gets an email with a link that
points to www.yoursite.com/process_activation/<ACTIVATIONCODE>
There is a "Mailman" model which is your ActionMailer.

def process_activation
  if user = User.find_by_activation_code(params[:id])
    user.active = true #or however you mark a user as fully active
    user.save
    Mailman.deliver_after_activation(user)
    redirect_to... and return #this is where a validated user should
go
  else
    flash[:error] = "Invalid Activation Code"
    redirect_to... #or do whatever you want here when someone has an
invalid code
  end
end

This isn't 1000% secure, it doesn't actually match the user with the
code, etc.  But it's good enough for me. If it's not good enough for
you then it's easy enough to adapt.

Of course, you need a standard ActiveMailer model and view.  'user'
will be passed to it.

Hi Andrew,
Thanks for the interest.Actually this is not the problem Im facing. Rite 
now Im using restful authentication plugin, and with this Im able to 
send the email after user has clicked on the activation link. But what I 
really want is that no email should go to the user after he activates 
himself.What I really want is that only after the activation when the 
user first logs into my site, then only an email should be sent to him. 
I think some sort of tracker is needed for the  user login. But Im not 
really understanding on how to do it

Hi Andrew,
Thanks for the interest. But this is not my problem. Rite now Im able
to send the email once the user clicks on the activation mail. But
what
I really want is that the welcome email should go to the user only
after he first logs into my website.
Im using restul_authentication plugin

my user_observer.rb file is
class UserObserver < ActiveRecord::Observer
  def after_create(user)
    UserMailer.deliver_signup_notification(user)
  end

  def after_save(user)

    UserMailer.deliver_activation(user) if user.pending?

  end
end


So when a user signs up initially the mail having the activation link
is being sent. When the user clicks on the activation link, another
email is sent to the user. But I want this second email to sent only
after he logs in the site for the first time. I m stuck here.

I was thinking that you could have an initial_login boolean field in
your users table that could initially be set to false.  Each time a
user logs in, you could call a method that sees if the user has logged
in before (i.e., is initial_login still false?), and if not, sends the
user an email and sets initial_login to true.

You could also use a 'last_logged_in_at' field that's null by
default.  The email gets fired in response to the first login (field
null=>value) and you also get a field that helps you understand how
much your users are using the system (and the chance to send "You've
been away for a while..." emails).

Bro, it's simple question. What do you call for after_create or 
after_save? is it called trigger? if yes, can i write trigger in modul? 
or helper?

Thanks,
