Django homepage without cookie before login
I see "we are using cookies" everywhere. I want to have my homepage without a cookie, if no one is logged in. I am using some REST-queries, if someone is logged in, so later on cookies are needed. Is that possible with django ? How ? I am using django 2.2.6. -
Django- "python manage.py runserver" not working
Hi im new to django and i cant get my web server running. First of all i viewed several of other threads and ive been searching for a solution for 4 hours and i couldn't find any help. So this is what ive done: Installed django using the following "pip install django" Created a project using "django-admin startproject DjangoProject" Went into the directory using "cd DjangoProject" Inputted "python manage.py runserver" into the console and the console doesn't display anything. So ive tried several of methods to solve this issue and have even set up environmental variables C:\Python37\scripts C:\Python37 After setting up environmental variables when i input "python -m django --version" or "python manage.py runserver" i receive an output of "'python' is not recognised as an internal or external command,operable program or batch file." I think i haven't set up my environmental variables properly Have i set up my environmental variables properly? Or have i done something else wrong, I can't seem to figure out the problem. Any Help would be appreciated. -

Type object 'Token' has no attribute 'DoesNotExist'
In urls.py, I added token-auth url and I can successfully get token with right credentials: from rest_framework_jwt.views import obtain_jwt_token .... path('token-auth/', obtain_jwt_token), In Postman I tried to hook this method with jwtToken variable like this: var data = JSON.parse(responseBody); postman.setEnvironmentVariable('jwtToken', data.token); Than I tried to call another URL which starts like this: class MyRequestView(viewsets.ModelViewSet): permission_classes = (IsAuthenticated,) authentication_classes = (TokenAuthentication, ) def list(self, request): .... In postman, when I call this method I tried to add an Authorization header: Authorization: Bearer {{jwtToken}} // Response: "Authentication credentials were not provided." Authorization: JWT {{jwtToken}} // Response: "Authentication credentials were not provided." Token returns a different response: Authorization: Token {{jwtToken}} > WrappedAttributeError at /mypath type object 'Token' has no attribute 'DoesNotExist' I also tried to add a Bearer Token manually but I still get "Authentication credentials were...." I added rest_framework_jwt among INSTALLED_APPS and my DEFAULT_AUTHENTICATION_CLASSES config has TokenAuthentication, SessionAuthentication and BasicAuthentication. What am I missing? -

How to generate unique results is django queryset?
I'm retriving a set of objects in django view using following query: shuffle(query) query2=list(ChannelPost.objects.annotate(num_images=Count('channelpostmedia')).filter(num_images__gt=0).order_by('-user_like').distinct()[:6]) query4=list(CommunityPost.objects.distinct().annotate(num_images=Count('communitypostmedia')).filter(num_images__gt=0).order_by('-user_like')[:16]) query3=list(Communities.objects.distinct().order_by('-points')[:5]) query5=list(channel.objects.distinct().order_by('-chaneldate')[:9]) shuffle(query2) shuffle(query3) shuffle(query4) shuffle(query5) query6=list(post.objects.order_by('-DatePosted')) The main problem with the queryset is the fact that the result always contain duplicate objects which is undesirable. -

Two Django Views that throw "Internal Error 500" only when in production
I have a website that works perfectly fine in my development environment but throws an Internal Error (500) in production on a Debian 9, Nginx, and Gunicorn setup. Here are the troublesome views: @login_required def post(request): if request.method == "POST": form = ListingForm(request.POST, request.FILES) if form.is_valid(): post = form.save(commit=False) post.lat, post.lng = get_lat_lng(google_api_key, post.street_address + ", " + post.city + ", " + post.state) post.save() return redirect('post_view', pk=post.pk) else: form = ListingForm() return render(request, 'post.html', {'form': form}) @login_required def post_edit(request, pk): post = get_object_or_404(Listing, pk=pk) if request.method == "POST": form = ListingForm(request.POST, request.FILES, instance=post) if form.is_valid(): post = form.save(commit=False) post.lat, post.lng = get_lat_lng(google_api_key, post.street_address + ", " + post.city + ", " + post.state) post.save() return redirect('post_view', pk=post.pk) else: form = ListingForm(instance=post) return render(request, 'post_edit.html', {'form': form, 'post': post}) And here is an example of a view that works completely fine in production with similar functionality: @login_required def new_attorney(request): if request.method == "POST": form = AttorneyForm(request.POST, request.FILES) if form.is_valid(): post = form.save(commit=False) post.save() return redirect('attorney_edit', pk=post.pk) else: form = AttorneyForm() return render(request, 'new_attorney.html', {'form': form}) I'm kind of freaking out because this is a time sensitive project we need live soon, and I have no clue what's causing this error. … -

Chromium print-to-pdf adding space above images
The background I have a simple document making system which is part of a Python Django application.

Heroku logs says: "No web processes running"
I made a website with django and tried deploying it using Heroku. After deploying, I can't access to it and Heroku log shows the following error : at=error code=H14 desc="No web processes running" method=GET path="/favicon.ico" host=pur-beurre-oc8.herokuapp.com request_id=9e33d4c8-83d6-4214-baf8-e4d1023b43ff fwd="176.134.6.63" dyno= connect= service= status=503 bytes= protocol=https After looking through some similar problems, I tried: heroku ps:scale web=1 and got: Scaling dynos... ! ▸ Couldn't find that process type (web). I tried to remove and add buildpacks: heroku buildpacks:clear heroku buildpacks:add --index heroku/python but this last command return to me: Error: Expected an integer but received: heroku/python at Object.parse (/snap/heroku/3832/node_modules/@oclif/parser/lib/flags.js:17:19) at Parser._flags (/snap/heroku/3832/node_modules/@oclif/parser/lib/parse.js:152:49) at Parser.parse (/snap/heroku/3832/node_modules/@oclif/parser/lib/parse.js:113:28) at Object.parse (/snap/heroku/3832/node_modules/@oclif/parser/lib/index.js:25:27) at Add.parse (/snap/heroku/3832/node_modules/@oclif/command/lib/command.js:83:41) at Add.run (/snap/heroku/3832/node_modules/@heroku-cli/plugin-buildpacks/lib/commands/buildpacks/add.js:7:36) at Add._run (/snap/heroku/3832/node_modules/@oclif/command/lib/command.js:44:31) So I do not know what I'm doing wrong My Proficle is like this: web: gunicorn pur_beurre.wsgi I tried to change Procfile like this: web: gunicorn pur_beurre:app or this: web gunicorn pur_beurre:app but heroku ps:scale web=1 still not working
