Question

I am calling a partial in one of my views like so:

<%= render :partial => 'events/attendees', :collection => @attendees %>

the partial however is running twice for some reason…here is the partial:

<% @attendees.each do |user| %>

    <li><%= link_to user.name, user %></li>

<% end %>

and i verified that rails is in fact running this partial twice because the output shows each item from @attendees twice

Answer 1

That’s because one “loop” is from Rails (:collection means that Rails will render the partial for each item in the collection, in this case @attendees) and one loop via your own partial.

Change the partial to below (not sure about the relation between attendee/user, but here is a sample):

<li><%= link_to attendee.name, attendee.user %></li>

Or, change the call of the partial to:

<%= render :partial => 'events/attendees' %>
