I have a piece of code like below which is truncated for concise: bargained_count = BargainLog.objects.filter(bargain_start_log=bargain_start_log).count() ... money = calc_single_bargain_money( bargained_count=bargained_count, ...... ) ... BargainLog.objects.create(bargain_start_log=bargain_start_log, money=money, ...)
bargained_count is a parameter of func calc_single_bargain_money. But, because of the race condition, I am not sure if this is one kind of race condition. I may get bargained_count as same values in high concurrency which will affect the result of calc_single_bargaiN_money. So, how should I avoid it, please give me some advice. Like in multi threading, I want to add a lock before getting bargained_count and release the lock after creating new BargainLog instance to ensure they are bundled together. -- You received this message because you are subscribed to the Google Groups "Django REST framework" group.
