Should just be @location = @event.location. You have a typo in that
Locatios.find is plural instead of singular.
Ha! That worked. :)

Bob -
Unless I'm not understanding your question, I think this is exactly
what Partials were designed to do: let you keep a snippet of erb
code to render locations with the rest of the views for locations
and then let you call it from anywhere.
Right, and I'll probably shift to partial, but the catch when using
render is that it does not execute the other controller's action
code. So, if you have controller XYZ with action 'show' and a
show.html.erb, "render XYZ/show" will choke if it depends on a
variable set in action XYZ.show. So even a partial would have choked.
The secret above is that "@location = @event.location" needs to be
set in the show action of the Events controller, which i suppose is
fine since I've defined the one-to-many association (an event must
have a location) but it doesn't seem to me to be cleanly OO. (?)
Of course, as soon as I get the answer, I discover something else
that works. From http://guide.rails.info/layouts_and_rendering.html:
----
Every partial also has a local variable with the same name as the
partial (minus the underscore). You can pass an object in to this
local variable via the :object option:
<%= render :partial => "customer", :object => @new_customer %>
Within the customer partial, the customer variable will refer to
@new_customer from the parent view.

I swear I read that section twice and didn't see that little tidbit.
So! What I've got now is,
<%= render :partial => 'locations/location', :object =>
@event.location %>
after copying show.html.erb to _location.html.erb, and changed all
the "@location.xyz" refs to "location.xyz" (eg: location.name, etc).
That works!
I can actually feel myself getting smarter. You guys are awesome.
Thanks!
