Django video uploads new video not display
I'm using django 3, when I upload a video from the admin panel, it doesn't appear on the page. When I go to the video url, I get a 404 error, but my old uploads are visible, and the newly uploaded files are not visible.

serve() is called twice everytime I reload a blog page in wagtail
I am using wagtail to build a blog website. In order to count the visits of each blog, I override the get_context() and serve() to set cookie. The codes are as follows: def get_context(self, request): authorname=self.author.get_fullname_or_username() data = count_visits(request, self) context = super().get_context(request) context['client_ip'] = data['client_ip'] context['location'] = data['location'] context['total_hits'] = data['total_hits'] context['total_visitors'] =data['total_vistors'] context['cookie'] = data['cookie'] context['author']=authorname return context def serve(self, request): context = self.get_context(request) template = self.get_template(request) response = render(request, template, context) response.set_cookie(context['cookie'], 'true', max_age=3000) return response And the function count_visits is as follows: def count_visits(request, obj): data={} ct = ContentType.objects.get_for_model(obj) key = "%s_%s_read" % (ct.model, obj.pk) count_nums, created = VisitNumber.objects.get_or_create(id=1) if not request.COOKIES.get(key): blog_visit_count, created =BlogVisitNumber.objects.get_or_create(content_type=ct, object_id=obj.pk) count_nums.count += 1 count_nums.save() blog_visit_count.count += 1 blog_visit_count.save() The problem I met is that when I reload the blog page, serve() was loaded twice. The first time request was with cookie info. But the second time the cookie of the request was {}, which caused the count of visit does not work correctly. I do not understand why serve() is called twice everytime I reload page. -
How to check if the email/username already exists in the db in django?
How to check if the email_id/ username already exists in the database in django? I want to check the existence of the email/username in the views rather than in serializer.

Display field from another model in ModelAdmin of User model
My Django project is based on built-in User model. For some extra attributes, I have defined another model: models.py: class Status(models.Model): email = models.ForeignKey(User, on_delete=models.CASCADE) is_verified = models.BooleanField(default=False) is_active = models.BooleanField(default=False) def __str__(self): return self.email And here's the custom ModelAdmin: admin.py: class CustomUserAdmin(UserAdmin): model = User list_display = ['email'] search_fields = ['email'] I want list_display to show me is_verified and is_active fields from Status model but I'm lost. I've looked into some similar questions on SO like Display field from another model in django admin or Add field from another model Django but none of the solutions are applicable because one of my models is Django's built-in. -

Difference between request.user vs. get_user(request) in Django?
I noticed there are two ways to get a user object from request (assuming user is already logged in and the session is valid): user = request.user user = get_user(request) where get_user() is imported from django.contrib.auth. What's the difference? get_user() seems to do a lot of validation for request session. Which is better? -

Is celery-beats can only trigger a celery task or normal task (Django)?
I am workign on a django project with celery and celery-beats. My main use case is use celery-beats to set up a periodical task as a background task, instead of using a front-end request to trigger. I would save the results and put it inside model, then pull the model to front-end view as a view to user. My current problem is, not matter how I change the way I am calling my task, it always throwing the task is not registered in the task list inside celery.
