Models has change in Django but they are not reflected in celery
I have a Django project running inside a Docker container. Celery Worker, Celery Beat, Redis and Postgres are running inside it containers too. My problem is that i made some changes in a Django model then generate migration, applied it and everything works. When celery tries to save an instance of that model, i get the classic Django error: The col non exists. My question is: Do i have to do something like apply migrations in celery? Thanks for your help, Regards. -
Django Rest Framework and url shortcuts
I have a url: path('reservations/', views.ReservationViewSet.as_view(dict(get='list', post='create')), name='reservations'), so I will call it like: reservations?restaraunt=3 and I want to have a shortcut for it: path('restaurants/<int:restaurant_id>/reservations/', views.RestaurantReservationsForwardView.as_view(), name='restaurant-reservations'), which I gonna call like restaurants/3/reservations so, I have two views: class ReservationViewSet(viewsets.ModelViewSet): queryset = models.Reservation.objects.all() serializer_class = serializers.ReservationSerializer def get_queryset(self): queryset = super().get_queryset() restaurant_id = self.request.query_params.get('restaurant', None) if restaurant_id: queryset = queryset.filter(restaurant=restaurant_id) return queryset def create(self, request, *args, **kwargs): request.data['restaurant'] = request.query_params.get('restaurant') return super().create(request, *args, **kwargs) class RestaurantReservationsForwardView(View): @method_decorator(csrf_exempt) def dispatch(self, request, *args, **kwargs): request.GET = request.GET.copy() request.GET['restaurant'] = kwargs.get('restaurant_id') return ReservationViewSet.as_view(dict(get='list', post='create'))(request) It works but I fill like inventing the will.

Django - how to log error and display message
Currently, we use django logger to log errors and send emails to admin. # settings.py 'handlers': { 'mail_admins': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler', }, 'applogfile': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', } }, 'loggers': { 'django': { 'handlers': ['applogfile', 'mail_admins'], 'level': 'ERROR', }, } We want to create custom user error page so we created a middleware to process exception: # exceptionMiddleware.py class ExceptionMiddleware: def process_exception(self, request, exception): message = str(exception) if isinstance(exception, BusinessLogicException) else "Sorry, we encountered an unexpected error" return HttpResponse( message ) The problem with this middleware is that the logging mechanism stop working. How do I get the loggers that are set up in settings.py to run from exceptionMiddleware.py? Thanks! -
Removing old permissions from a model in DJANGO
I changed the name of a model. It was called "Riesgo asociado", I changed it to "Reglas", then to "Regla" and applied the migrations, everything was ok. But now I have change, delete, view and add permissions for each name, even tho they are the same model. I need to change this because all this permissions are displayed in a custom admin view and those permissions for the old names are useless. -
How would I make a user who is verifed have a blue tick next to their name in Django
I would like to know how I would go about adding a system so that if a user if verified, a tick will appear next to their name. I think I will have to make a variable called verifed and make it a bool and only admins can change it. So how would I display an icon next to their name if verified == True? I haven't tried anything because whenever I Google it, tutorials on how to get verified on Instagram flood everything -

Wagtail - use same slug multiple times
I would like to have a structure like this on a site: learn.com/math/lessons learn.com/english/lessons learn.com/science/lessons In wagtail, the "lessons" slug would get used three times. At least out of the box, that doesn't seem allowed. Is there a wagtail setting I can override to achieve this structure? Or is there a better method? The closest I've been able to get is creating three sites and then writing a filter that gets the leason page under a certain root page. But I really would like everything on one site. -

Django When does cache expire?

How does web (Django) cache works?
When server caches a page, I thought it worked like this, but apparently I'm wrong. server stores http response contents in a cache-store with a key (that's generated for the endpoint) one could create separate cache key for certain aspects of requests (such as user language) when there's a request for the same key, and it's stored in cache-store (such as redis), webserver returns the cached response instead of recreating the response I think the above understanding is flawed because,, when I hit the endpoint with axios, first request is hit on the server, but the second request doesn't even hit the endpoint, it seems axios is reusing the previous response it received. So, if I clear all cache store between two requests, the second request doesn't get to the request handler (view function in django) In django, I'm using from django.views.decorators.cache import cache_page But the question is more of general working of web response cache
