In my application there are 2 models - Profile and Topic. Profiles can
be attached to topics and hence I have a many to many relationship
between them. Things were good until recently I encountered a problem
that said “stack level too deep”. I’m using Rails 2.2.2 and Ruby 1.8.6
My controller method looks like this:
def show
@topic = Topic.find(params[:id])
@attachments = @topic.profiles
end
Looks pretty trivial.
On the view, I am iterating through the attachments and calling a
partial by sending every attachment as a local variable
My view looks like this -
<% for profile in @attachments %>
<% p profile %>
<% p profile.id %>
<% p session[:user] %>
<% onclick_expand = “expand(‘show_chart_button_#
{profile.id}’,‘attached_chart#{profile.id}’)” if session[:user] %>
<%#= current_user ? (render :partial=>’/profile/
chart_partial’, :locals => {:profile => profile}) : “Please <a href=”/
“>login to view the chart.” -%>
However, even before the partial is called, I get “stack level too
deep error”, on lines where I try to inspect the profile object and
its attributes, after waiting for a long time. Before inspecting the
profile object, I was getting the same error on line no. 33 (See the
log below)
My log looks like this -
ActionView::TemplateError (stack level too deep) on line #31 of app/ Topic Attachments
views/topic/attachments.html.erb:
28:
29: <% for profile in @attachments %>
30: <% p profile %>
31: <% p profile.id %>
32: <% p session[:user] %>
33: <% onclick_expand = "expand('show_chart_button#
{profile.id}’,‘attached_chart#{profile.id}’)" if session[:user] %>

I have no clue about why this is happening. This is something not
complex at all and I have done it hundreds of times. Can someone
please help me out here?
