I'm coding a site that's using tags. Two other classes (Foo and Bar) both will use tags, but the tags used in Foo won't apply to Bar, and vice-versa. So I created the Tags table with both foo_id and bar_id columns, so when a record is saved, the foreign key for the correct object-type can be added. Will this cause problems? Is there ...

When the app was initially designed, it was assumed that the User would have different behaviors based on type. This assumption was wrong, so I'm looking to refactor. The question is how would you refactor out the User STI? Add a ton of boo...
