Does transaction.atomic roll back increments to a pk sequence
I'm using Django 2.2 and my question is does transaction atomic roll back increments to a pk sequence? Below is the background bug I wrote up that led me to this issue I'm facing a really weird issue that I can't figure out and I'm hoping someone has faced a similar issue. An insert using the django ORM .create() function is returning django.db.utils.IntegrityError: duplicate key value violates unique constraint "my_table_pkey" DETAIL: Key (id)=(5795) already exists. Fine. But then I look at the table and no record with id=5795 exists! SELECT * from my_table where id=5795; shows (0 rows) A look at the sequence my_table_id_seq shows that it has nonetheless incremented to show last_value = 5795 as if the above record was inserted. Moreover the issue does not always occur. A successful insert with different data is inserted at id=5796. (I tried reset the pk sequence but that didn't do anything, since it doesnt seem to be the problem anyway) I'm quite stumped by this and it has caused us a lot of issues on one specific table. Finally I realize the call is wrapped in transaction.atomic and that a particular scenario may be causing a double insert with the same … -

Dockerizing django, postgres, gunicorn, ngnix - only admin static works, other 404
As in topic. I have tried to apply solutions I found in internet, but no success :( I am pretty new to programming and as making an app is one thing, deploying it just overwhelmed me. I have managed to put it on server, run it on docker with SSL, but main problem is that only admin static files load, other give 404 error. Weird thing is that static subdirectories structure is kept, but there are no files inside. Please help me, I am really stuck :( If you require any other data, please write Note that neither STATIC_ROOT or STATIC_DIRS work (in some cases changing it helped, not here).
