Rails - Nov 2010 - Re: Train wreck getting render_to_string to work from foreign controller [SOLVED]

Just for collective knowledge as I have found no info on this problem
online:

I solved this by adding an .html.erb file for the "missing template",
since
by design or bug Rails3 will not find or render another controllers view (in
my experience). Then in the new html.erb file, I just put <%= render
"comparisons/display" %> because the views *are* able to find
templates from
another controller.

It seems like this is more work, but I can see that perhaps this was done by
design as it forces me to more cleanly define what the controller actions
render.
