I have what I think is a very simple problem (famous last words)...
I have a Category
model that has_and_belongs_to_many
Events
. I want to construct a simple and efficient query that finds all categories that have 1 or more events. (using Rails 3)
I'm sure I'm having a dumb moment here - any help appreciated :)
