Question

I have a User model (with Devise), and a Post model that belongs to the user. I used this railscast (pro) to send the User an email after creating an account

I created a “NewPostMailer”

This is my mailer:

class NewPostMailer < ActionMailer::Base
  default :from => "[e-mail]"

  def new_post_email(user)
    @user = user
    @url = "http://localhost.com:3000/users/login"
    mail(:to => user.email, :subject => "New Post")
   end
end

My posts_controller:

  def create
    @post= Post.new(params[:post])

    respond_to do |format|
      if @deal.save
        NewPostMailer.new_post_confirmation(@user).deliver
        format.html { redirect_to @post, notice: 'Post was successfully created.' }

post.rb

  after_create :send_new_post_email

  private
  def send_new_post_email
    NewPostMailer.new_post_email(self).deliver
  end

What do I have to change to send the User an email after he creates a Post. Thanks.

Answer 1

Create another mailer (http://railscasts.com/episodes/206-action-mailer-in-rails-3)

 class YourMailerName < ActionMailer::Base
     default :from => "[e-mail]"

   def post_email(user)
    mail(:to => "#{user.name} <#{user.email}>", :subject => "Registered")
   end
 end

In your Post model

 after_create :send_email

 def send_email
   YourMailerName.post_email(self.user).deliver
 end

Sending an email is very slow so think about putting this in a background job.
