Not sure how you get 2 queries, but this seems like it gives right answer.
class User(Base):
__tablename__ = 'users'
id = Column(Integer, primary_key=True)
items = relationship('Item')
class Item(Base):
__tablename__ = 'items'
id = Column(Integer, primary_key=True)
user_id = Column(Integer, ForeignKey(User.id))
q1 = session.query(User.id, func.count(Item.id)).\
join('items').\
group_by(User.id).having(func.count(Item.id)>5)
Check out the documentation for Query.join for alternatives on the join
parameter
http://www.sqlalchemy.org/docs/06/orm/query.html#sqlalchemy.orm.query.Query.join
for example: if the "items" relationship isn't declared
.join((Item,User.id==Item.user_id))
generates the same SQL
