Python Session.delete Examples

Example #1

def changestuff():
    session = Session()
    a1, a2 = session.query(A)
    b1, b2, b3 = session.query(B)
    a1.name = "first a modified"
    b2.a = a2
    session.delete(b3)
    session.commit()

Example #2

File: conflict_detection_tests.py Project: bintlabs/python-sync-db

def changestuff():
    session = Session()
    a1, a2 = session.query(A)
    b1, b2, b3 = session.query(B)
    a1.name = "first a modified"
    b2.a = a2
    session.delete(b3)
    session.commit()

Example #3

def teardown():
    session = Session()
    # map(session.delete, session.query(A))

    for a in session.query(A).all():
        session.delete(a)
    for b in session.query(B).all():
        session.delete(b)
    for op in session.query(models.Operation).all():
        session.delete(op)
    for ver in session.query(models.Version).all():
        session.delete(ver)

    session.commit()

        session.delete(b)
    for op in session.query(models.Operation).all():
