Invite a friend invitation system error
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> <% end %> </ul>
The output displayed on the site is as follows:

<% for invitation in @emails_for_invitations do %>
without the equals sign "=" will get rid of the output. The reason is you tell rails to render the return value of your for loop, which happens to be each individual invitation object as it looks ...
