Hi, i haven't disappointed with the concept behind the Transaction, But i lost the opportunity to call methods one by one. I used the below patterns few min ago. Of course it works fine. But from the beginning part of this transaction to the end part i could not see any result. Maybe the method of development in my pc is different from others. I take advantages of interactive python to call functions quickly then i decide what to do in the real module. But here i have to put everything (For example 7 lines of code within the Transaction and then if i typed a mistake in the last one, I only get an error message. Previously it was faster. Anyway i checked your links , the new change is very nice in my point. But i always remember this rule in the world of IT that any advantage WILL have disadvantage.(this rule is true so far for me without exception)
