Django: never_cache is not working, it still shows same data on browser back button
I have a create view which is used to make an object of type Course(model). i'm using never_cache decorator to reload the page from server everytime i use it. now if i create a course it gets added in the Course database, now if i press browser back button it still shows me the data with course name that i wrote, which allows me to resubmit the same data, how can i prevent this?(ik i can prevent saving same data twice by overriding save method but i want to prevent user from going back to form in which he entered data). @method_decorator(never_cache, name='dispatch') class CourseView(CreateView): model = Course template_name = 'teacher/course.html' fields = ['name', 'year'] def get_context_data(self, **kwargs): kwargs['course_list'] = self.model.objects.all().order_by('name','year') return super().get_context_data(**kwargs) def form_valid(self, form): messages.success(self.request, 'Course added successfully.') return super().form_valid(form) def get_success_url(self): return self.request.GET.get(key='next', default=reverse('teacher:course')) -

Is using UUId as pk a good idea in microservices?
I am working on a microservice project which contains 4 services developed in django i use dj rest auth to handle login and register process , each service has its own database and the information of users are kept in account service and other 3 services get the users information via an api request to account service , in each service i have only access to logged in user pk (dj rest auth handles this) and when i need to save a record for example location of logged in user ,i save a user object which only has pk alongside other info so the record in db will be like this : user=request.user(which saves logged in user but i only see the pk) lat = latitue number lng = longitude number everything is fine but if i loose the database of account service and restore the backup and some how the records generate a different pk (for example before restoring backup some new records would be added) from the ones saved in other services which makes a huge problem in all services. the solution i tried is to change the pk to uuid filed but is it a good idea? … -
Keywords Must Be Strings When Passing Variable As Parameter
I'm trying to pass a variable as a keyword argument like this: true_frequency = 'weeks' next_month = today + relativedelta(**{true_frequency: true_loop}) This is for a django site and it doesn't error when I run this through the site. However, when I run a test I'm getting this error: next_month = today + relativedelta(**{true_frequency: true_loop}) TypeError: keywords must be strings I'm not entirely sure how to solve this as I've never passed a keyword as a variable before so I'm not overly familiar with the process. This is happening on a receiver object. Thanks -

DJANGO: caching a services.py method so it's always available
I'm trying to use this python ML library and turn it into an APIView for my project. There is a single line that loads the ML model which took around ~20s, so I separated that line into services.py and decorated with @lru_cache so it doesn't always take ~20s. Because lru_cache is Least Recently Used caching method, the cached model is quickly un-cached and makes user wait for another 20s sooner or later. So I am looking for a way to either cache load_model() method so it's always available, or cache it within a certain time. I tried using cache_page method for the latter but had no luck so far. Is there a better method I can use, or would just tweaking the lru_cache's maxSize be a more elegant solution? This APIView isn't called very often, which makes user wait ~20s every time. I was hoping to just make it always available so user don't have to wait. views.py from .services import load_model, extract_keyword class ExtractKeyphrase(ApiAuthMixin, APIView): def post(self, request): try: text = request.data["text"] kp_model = load_model() # the line that takes ~20s keyphrases = extract_keyword(kp_model, text) return JsonResponse(keyphrases, status=status.HTTP_200_OK, safe=False) except requests.exceptions.RequestException: Response("Request Failed", status=status.HTTP_400_BAD_REQUEST) services.py from functools import lru_cache … -

How to set "DJANGO_SETTINGS_MODULE" for a "config" module divided into common, local, production files
I'm setting up a wsgi.py to deploy my django app in DigitalOcean, but I'm getting the following errors during deployment phase after successful build.
