How can I send email to email contact in rails app form?

Question

I want to have a form in my app where a logged in user can input their friend's email addresses, click send, and it will send out an automated email to the email addresses that they entered into the form. Here is what I have so far. I get unitialized constant when I click on the button to take you to the form so I don't know what else isn't working too.

invitations_controller.rb

class InvitationsController < ApplicationController
def new
    @invitation = Invitation.new
end

def create
     @invitation = Invitation.new(params[:invitation])
     @invitation.invited_by = current_user.invitation_token # set the sender to the current user
     if @invitation.save
      Mailer.invitation(@invitation, new_user_path(:invite_token =>  @invitation.invited_by)).deliver #send the invite data to our mailer to deliver the email
     else
      flash.now[:notice] = "Something went wrong"
      redirect_to root_url
     end
    end
   end

mailer.rb

class Mailer < ActionMailer::Base
 default from: "donotreply@mysite.com"

 def invitation(invitation, signup_url)
  subject    'Invitation'
  recipients @recipient_email
  from       'donotreply@mysite.com'
  body       :invitation => invitation, :signup_url => signup_url
  invitation.update_attribute(:sent_at, Time.now)
 end
end

invitation.html.erb

Mailer#invitation
You are invited to join our beta!

<%= signup_url(@invitation.invited_by) %>

new.html.erb (invitation form)

    <%= simple_form_for @invitation, :url => new_invitation_path do |f| %>
    <%= f.hidden_field :invitation_token, :value => @invitation.invited_by %>
    <%= f.label :email %>
    <%= f.email_field :email %>
    <%= f.submit 'Send' %>
    <% end %>

I can't even get to the invitation form because I get the uninitialized constant error. So for all I know it works beyond that. Help please

You need an Invitation model.

rails generate model Invitation invited_by:string sent_at:timestamp
