How to set a timer inside the get request of an APIView?
I am trying to build a timer inside a get method in a DRF View. I have created the timer method inside the GameViewController class and what I am trying to achieve is that a every minute (5 times in a row) a resource object is shown to the user through the get request and a game round object is created. My View works at the moment, however the timer doesn't seem to be doing anything. I know this isn't exactly how things are done in django but this is how I need to do it for my game API for game logic purposes. How can I make the timer work? Do I need to use something like request.time or such? Thanks in advance. views.py class GameViewController: def timer(self): """Start a new timer as soon as a gameround has been started/created""" start_time = datetime.now() elapsed_time = None if start_time is not None: elapsed_time = time.perf_counter() """Stop the timer, and return the elapsed time""" if start_time is None: elapsed_time = time.perf_counter() - start_time return elapsed_time ... class GameView(APIView): def get(self, request, *args, **kwargs): ... round_number = gametype.rounds time = controller.timer() while round_number != 0: if time >= 1: random_resource = Resource.objects.all().order_by('?').first() … -

I've been writing a test with RequestFactory to test one of my views, with the following code: class ViewTestCase(TestCase): @classmethod def setUp(self): self.factory = RequestFactory self.user = User.objects.create_user( first_name='tester', username='test1', password='123', email='testuser@something.com' ) def test_room_creation(self): payload = {"titlePlanning": "Test1","styleCards": "Fibonnaci","deck": ["1","2","3"]} request = self.factory.post('/room', payload) request.user = self.user response = BeginRoom.as_view()(request) self.assertEqual(response.status_code, 200) This is the data that I need to send to use POST: class BeginRoom(APIView): permissions_classes = (IsAuthenticated,) def post(self, request, format=None): data= self.request.data user = request.user name = data['titlePlanning'].strip() styleCards = data['styleCards'] cards = data['deck'] My problem is that whenever I run my tests I get the following error: data = self._encode_json({} if data is None else data, content_type) AttributeError: 'str' object has no attribute '_encode_json' What should I do? I'm lost from here and can't find anything related. Any help is appreciated! -

How to show in templates if a scheduled end of project is delayed based on end date in django?
I'm kinda stuck with a logic wherein if a project that is past it's due date and it's progress value is still not in 100% completion it should show a delayed text or if it's progress is still not in 100% but in the range of date end it should show an ongoing text.

How to filter objects in Django by time since last 24 hours?
Assuming there's a starting time from 00:00 to 00:00 every day, how best are Django objects filtered by time, based on the current day? I initially came up with this: from django.utils import timezone yesterday = timezone.now() - timezone.timedelta(1) qs = Foo.objects.filter(date__gte=yesterday) ## yesterday = datetime.date.today() - datetime.timedelta(1) qs = Foo.objects.filter(date__gte=yesterday) However, this is not particularly right. I would prefer time starting exactly from 00:00 to timezone.now() -so something like Foo.objects.filter(date__range=[00:00, timezone.now()]) Thank you. -

Running Several Server and Clients From a Shared Local Drive?
I have devolved a web application that manages prescriptions for a pharmacy. It uses a SQLite database, Django server, GraphQL API, and React on the frontend. It takes several weeks to get elevated privileges for any task so I have installed all of this software without admin rights (nodejs, npm, py, etc). All of the software is installed into a shared drive so all of the computers may access the files. Also, please note that all of the data must be local and can not be hosted by a third party; I also doubt they will be able to host it on a server themselves. So right now I have a .bat file that starts up the Django server and runs the React production build (npm run build, serve -s build). The problem is when several users try to use the React build it gives a Server Error 500 msg. My question is: Is there a easier way to run the Django/react builds without having to make one copy of the repository in the shared drive per user? Additionally, is it okay to have several Django servers connected to the SQLite database or should I do something else? -

How to get real path instead of fakepath while using AJAX with DJANGO?
I am trying to get real path of image where it is uploaded in the local directory instead of fakepath. Before using AJAX, I was able to get the real path but to stop the page refreshing on each time form is submitted ( the reason is I wanted the current values present and not to go back to the default values each time form is submitted ), I incorporated AJAX. I understand its a security measure and all that but I am working in local environment and does anyone have any work around that? What I want is something in the top link ( I got this link by submitting values through admin ) but what I am getting is something in bottom ( through submit button on form ).

Google app engine Django app is crashing intermittently but the log files aren't showing me why
