Asking for help for in_place_editor_field

The in-place editor works for me, but not when I’m iterating over
objects in an array. I have the following in my view:
<% @session_types.each do |s| %>

<%= in_place_editor_field :s, 'name' %>

<% end %>

@session_types is an array of objects that have the attribute ‘name’.
However, I’m getting the error message:
Called id for nil, which would mistakenly be 4 – if you really wanted
the id of nil, use object_id

Nevermind. I found the answer here:

Thanks for posting the link… I beat my head over that for a hour or so
the other day and gave up (wanting to save my question karma for more
pressing needs!)
