I got models: - Post (id, thread_id, text, pid) - Thread (id, name, last_pid)
PID is the number of post in thread. So it needs to be unique to each thread. Like: Thread 1 : [1, 2, 3, 4, 5] Thread 2 : [1, 2, 3, 4, 5, 6, 7] And the "last_pid" field of thread is cache of pid of last post in post_set. How can last_pid update method be properly build? Today I'm incrementing last_pid on each post creation and assigning incremented value to new_post.pid. The problem of this variant is: if many users post simultaneously, some posts would have duplicate PIDs: [1, 2, 3, 3, 2, 4, 5] I don't know if this is a bug, but it can't be reproduced with built- in-django http server, I only see it with apache or nginx. -- You received this message because you are subscribed to the Google Groups "Django users" group.
