Question

I am trying to implement an invitation feature on my site. I am trying to display on each user’s page a list of the people they have invited. In my invitations controller I have the following code:

def index
    @invitation = Invitation.new
    @emails_for_invitations = Invitation.find_all_by_sender_id(current_user.id)
    @referred_users = User.where(:referer => current_user.id)
end

In my invitation view I have the following code:

<h1>Sent Invitations</h1>
    <ul>
    <%= for invitation in @emails_for_invitations do %>
      <li><%= invitation.recipient_email %></li>
