Comment (by boonebgorges):

 Also:

 - We should be cognizant of null vs `0` vs `'0'` as much as possible.
 [attachment:6977.BP_Friends_Friendship.patch] will mean that a failed
 lookup results in a `BP_Friends_Friendship` object where, eg,
 `initiator_user_id` is `null`. I think this is good - better than `0`,
 which would be misleading - but either way, we should try to be
 consistent.
