Django error: Relation "<name>" already exists
I am attempting to run migrations on an existing model where i am adding a history field/table via the django-simple-history.

django json.loads() of string of list
I'm trying to save a list of ids as a string and then turn it back to a list and use it's values for filtering a queryset. So first I do something like this - my_items_ids = list(Item.objects.filter(....).values_list('id', flat=True)) which returns list of UUIDS - [UUID('ef8905a7-cdd3-40b8-9af8-46cae395a527'), UUID('0904bcc4-7859-4c38-a2f9-94a4a2b93f0a')] Then I json.dumps it so I get - "[UUID('ef8905a7-cdd3-40b8-9af8-46cae395a527'), UUID('0904bcc4-7859-4c38-a2f9-94a4a2b93f0a')]" Later on I want to use those IDs for filtering again. something like - my_items = Item.objects.filter(id__in=my_items_ids) Since it's a string I'm trying json.loads(my_items_ids) first and I get json.decoder.JSONDecodeError: Expecting value: line 1 column 2 (char 1) I also tried to turn the UUIDs in the list to strings before the json.dumps() but I got the same results. -

Django POST Question for Hangman Game - Cant Update More Than One Letter
I'm working on a Hangman game using Django and trying to update the correct letters guessed in the word on the page. It seems I can get one letter at a time but not more than one to update the word as the game progresses. Its almost like a new list is initializing each time the function is called. Any suggestions? Here is my code, the 'else' is defaulted off a post request. Any buttons clicked from the keyboard are sent to a function where I handle the POST request, one button at a time. I'm a little unfamiliar working with HTTP requests/responses so any help would be appreciated. else: game_id = int(request.POST['game_id']) letter_guess = request.POST['letter'] game = Game.objects.get(game_id=game_id) game.guess = letter_guess split_answer = game.answer.split() answer1 = split_answer[0] len1 = int(len(game.display1) / 2) word1 = list(range(len1)) for x in range(len1): if answer1[x] == letter_guess: word1[x] = answer1[x] + " " else: word1[x] = "_ " word1 = "".join(word1) game.display1 = word1 game.save()
