2017-12-10 Thread Tolstov Sergey
Mike, very thanks for answer. I just use custom function and add to object 
session. I create some lists to save object and after rollback i add them
On this func i just use session.dirty, session.new, session.delete
for rollback i use
 
 def user_commit():
...
config.session.rollback()
 ...
for item in saved_items():
  config.session.add(item)
...
config.session.commit()

config.session.user_commit=user_commit
