Profile "relation username slug" alternative
I'm using a profile system as each user can see. I'm looking for an alternative. Because if a user register from FB or Google he always has "." in username. So if I want to reach his profile with slug I got a 404 error. Because username != slug. Do you have any idea? In my UserProfile I got unique slug for each user. def userpublicpostview(request, slug): userid = get_object_or_404(User.objects.select_related('userprofile'), username=slug) posts = Post.objects.filter(author_id=userid.id) comments = Comment.objects.filter(user_id=userid.id) pictures = Picture.objects.filter(user_id=userid.id) story = Story.objects.order_by('-created_on').all() return render(request, 'user_public_profile.html', { 'user_posts': posts, 'current_user': userid, 'user_comments': comments, 'user_pictures': pictures, 'story': story, }) -

Needing help: Trying to receive a POST request on a django server from an external piece of hardware
okay here is the deal: i'm rather new to this, so i don't know much. I have a piece of hardware, that is connected to my network, and i have a django server running. The hardware is able to send data in a specific typ, like this: $,,,,,*\r\n examples: $GPRP,CCB97E7361A4,CB412F0C8EDC,-49,1309696773206D65736820233220285445535429020106 so what i need is, to receive this information,maybe print it as a first step just for visualization,save it and then and process it. For exmple i need to have three of these hardware pieces and take every RSSI-value of them, and calculate with them, to get a new information out of it. The problem is, i dont know how to write that code, and i dont know what i should search for exactly to solve my problem. Maybe some of you can help! -
Making webpage hit count/trending section for blog
I am trying to make this simple feature of sorting by the most viewed articles in the last 24 hours. I did this by saving the timestamp every time the webpage gets a request. Now the most "trending" article is the one that has maximum timestamps saved in T-24 hours. However, I don't think that this is the right way to do it as the list keeps getting bigger, and it must be slowing down the webpages (which will become noticeable after a critical number of views).

In Django, how can the Graphene GraphQL endpoint be protected for API usage?
Graphene provides a GraphQL integration into Django and supplies a view to create a URL endpoint. The question is how can the endpoint be protected for API usage? The recommend method is to use a LoginRequiredMixin which is great for logged in users, but not for use as an API. I've tried integrating it with DRF tokens, but still end up with the session middleware requiring CSRF. The only solution that works is adding a CSRF exempt decorator, but I fear that this opens up a security vulnerability. # urls.py path("graphiql/", root_views.SessionGraphQLView.as_view(graphiql=True), name="graphiql"), path("graphql/", root_views.TokenGraphQLView.as_view(graphiql=False), name="graphql"), # views.py class TokenLoginRequiredMixin(AccessMixin): """A login required mixin that allows token authentication.""" def dispatch(self, request, *args, **kwargs): """If token was provided, ignore authenticated status.""" http_auth = request.META.get("HTTP_AUTHORIZATION") if http_auth and "Token" in http_auth: pass elif not request.user.is_authenticated: return self.handle_no_permission() return super().dispatch(request, *args, **kwargs) @method_decorator(csrf_exempt, name="dispatch") class TokenGraphQLView(TokenLoginRequiredMixin, GraphQLView): authentication_classes = [TokenAuthentication] class SessionGraphQLView(LoginRequiredMixin, GraphQLView): pass -

Can I use Django and HTML extensions at the same time in VSCcode?
I recently started learning Django and when I am writing templates, I have to switch between HTML and Django HTML extensions to use the tab for autocompletion. With the HTML extension, I can autocomplete the tags using the tab but when Django HTML is in use, it does not work anymore and have to write all the tags manually. Switching between the two is also frustrating, and sticking with the HTML extension means writing the Django syntax (eg. loops, if, and so on) manually also. Is there any extension that provides this? Or is there any way to use both at the same time? If not, even a quick shortcut for switching between the two would help. Thanks. -
