How is the best way to restrict a delete on an item if it has a value
in a many-to-many mapping?
For example:
I have three tables: User, Group, and UserGroup. UserGroup is a many-
to-many mapping table between User and Group. User has a relation
called 'groups' and Group has a relation called

how come the strack trace shows beta2 as the version number in the path ?
did you mean to say between beta1 and beta2 ? it looks specific to the C
rewrite of RowProxy. basically the rows returned by fetchone(), fetchall()
etc. are expected to be tuples. pep 249 specifies list of tuples
