Thanks, duh, that makes sense to me. I just created the database, and
now I'm going to start writing methods that connect everything with the
actions table so I can get some data in there.
I have a performance-related question. I don't think it'd be too
demanding to ask the action table "show me everything this user has
done" because it's just a :conditions => [:user_id = 1}. How crazy is it
to ask the actions table "show me every time someone else favorites or
comments on my recipe"? I believe this is possible with the actions
table you have laid out, but will it take a while to grind out of the
database?
