User Mailer Failing

I have setup a process in my User model to send a bunch of @users to a mailing script, user_mailer.rb

I am using the http://postageapp.com app to send out emails. The users are getting to the User_mailer but I am getting an error from there. Can anyone please point me in the right direction.

User Model:

class User < ActiveRecord::Base

  acts_as_authentic

  def self.mail_out

    weekday = Date.today.strftime('%A').downcase

    @users = find(:all, :conditions => {"#{weekday}sub".to_sym => 't'})




    UserMailer.deliver_mail_out(@users)



  end

end

User_mailer.rb

class UserMailer < ActionMailer::Base
    def mail_out(users)
    @recipients = { }
    users.each do |user|
      @recipients[user.email] = { :zipcode => user.zipcode }
    end


    from        "no-reply@dailytrailer.net"
    subject     "Check out the trailer of the day!"
    body        :user => user
  end

end

mail_out.html.erb

{{zipcode}},

Please check out the trailer of the day at http://www.dailytrailer.net


Thank you!

I'm not sure if this is the complete solution (what error are you getting?), but it's something that needs to be fixed: on the line body :user => user, the user variable is not defined. Do you mean to do :user => @recipients?

One thing I'm noticing in your code is that your mailer class is not deriving from Postage::Mailer.

So first make sure you have the latest PostageApp plugin installed and then look at some example code here: http://postageapp.com/docs/rails

There's also a sample app here: http://blog.postageapp.com/2009/11/rails-example-app/

Another detail I noticed in your code is in the line body :user => user is not needed because you're not using the user variable in your view besides the fact that, as Alex mentioned, it's not defined at that point.

Hope that helps!
