Wow, that was fast :)
You are right, the commit() here finally performs the delete. However, the
situation "main section" etc only arose in this script I compiled for
testing. The project uses Pyramid where transaction.commit() is called
automatically at the end of each request. And as I mentioned above, the same
code (without explicit commit()) works fine for Role and Principal, just
RoleMember sucks.
Good code from the controller for Principal
@view_config(name='xhr_delete', context='pym:resources.System_UsrMgr_User',
renderer='json')
def xhr_delete(context, request):
try:
id = int(request.POST['id'])
sess.query(_Entity).filter(_Entity.id==id).delete(synchronize_session=False)
sess.flush()
resp = { 'status': True, 'msg': 'Ok' }
return resp
except (StatementError, NoResultFound) as exc:
resp = { 'status': False, 'msg': repr(exc), 'errors':{} }
return resp
Bad code from the controller for RoleMember:
@view_config(name='xhr_delete',
context='pym:resources.System_UsrMgr_RoleMember', renderer='json')
def xhr_delete(context, request):
try:
id = int(request.POST['id'])
sess.query(_Entity).filter(_Entity.id==id).delete(synchronize_session=False)
#sess.flush()
transaction.commit()
resp = { 'status': True, 'msg': 'Ok' }
return resp
except (KeyError, StatementError, NoResultFound) as exc:
resp = { 'status': False, 'msg': repr(exc), 'errors':{} }
return resp
