schema validator must not allow userId to exist if there is a userPk
describe output may have to list userId
qualifiers need to convert userId into userPk
post/put needs to accept userId as input and convert to userPk
Might be better to actually store an extra column for these relationships as an extra column. Would then just have to make sure they can only be set via userPk, and not userId.
userPk will also be userId
