conditional table association?
I''m using a db to log two types of events, link events and tag
events. At first I had two tables, link_events & tag_events, but this
seemed not very DRY because the only column that was different
between them was link_id and tag_id respectively. So I made these
tables:
events:
id int
user_id int
objtype_id int (holds ''1'' or ''2'' depending on if the item is a link
or a tag)...
