Django Rest Framework OAuth2 Access Token Guidance Required
I'm trying to implement OAuth and jwt token login in Django Rest Framework for practice. I'm using social-auth-app-django and djangorestframework_simplejwt. I use the basic documentation and successfully created a user using GitHub (Checked that in Django Admin) and I also created a user using Simple CreateAPIView. For login purposes, I can use simple jwt to login and retrieve the access token to call the other authenticated APIs, but how can I do the same using an OAuth logged-in user account. Another problem I'm facing is, whenever to visit http://localhost:8000/api/auth/login/github/ in the browser is prompts my login screen, after login, it redirects me to http://localhost:8000/api/auth/complete/, which returns 404 because it's not the right endpoint as per the Django default error page. It represents api/auth/complete/<str:backend>/ [name='complete'] as one of the available endpoint. When I visit /api/auth/complete/github/ the error that comes up is AuthMissingParameter at /api/auth/complete/github/. I don't have any idea what is happening. My settings.py configurations are: INSTALLED_APPS = [ --- # Plugins "rest_framework", "corsheaders", "oauth2_provider", "social_django", "rest_framework_social_oauth2", --- ] REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": ( "oauth2_provider.contrib.rest_framework.OAuth2Authentication", "rest_framework_social_oauth2.authentication.SocialAuthentication", "rest_framework_simplejwt.authentication.JWTAuthentication", ), } AUTHENTICATION_BACKENDS = ( "rest_framework_social_oauth2.backends.DjangoOAuth2", "django.contrib.auth.backends.ModelBackend", "social_core.backends.github.GithubOAuth2", "social_core.backends.spotify.SpotifyOAuth2", "django.contrib.auth.backends.ModelBackend", ) -
Updating model with signals
now i'm trying to update field from my model with help of post_save signal. All works well in the admin page, but the field "number_of_photos" updates only after i click save button in the second time. Why is this happening? Signal code: @receiver(post_save, sender=PhotoAlbum) # noqa def count_photos(sender, created, instance, *args, **kwargs): # noqa instance.number_of_photos = instance.photos.count() signals.post_save.disconnect(count_photos, sender=PhotoAlbum) instance.save() signals.post_save.connect(count_photos, sender=PhotoAlbum) -
how to render data in django template that has been queried in backend using "__contains"
I am using django multiselect field in my model that is used to upload cases. Now I have a field in my model where the admin can select multiple categories for the same case. I have seperate pages to render this data according to the categories selected for them. I am filtering the data like this views.py law_data= Laws.objects.all().filter(sub_law_type__contains = 'ipc').order_by('-date') for law in law_data: print("\n these are the available cases : ", law.title," with sub law types : ", law.sub_law_type, "\n") return render(request, 'citation_ipc.html', {'law_data': law_data} ) here I want to filter all the cases that has ipc in it. And the result I am getting is this, which is accurate these are the available cases : dfsdf with sub law types : ipc, pocso, pmla, ni_act these are the available cases : dfgdfg with sub law types : ipc Now I am trying to render out this data in my html like this html <div id="sclimitations" class="tabcontent"> {% for data in law_data %} {% if data.law_category == 'limitations' and data.court_type == 'The Supreme Court of India' %} <div class="tab"> <div class="judge-content"> <a class="judge-ttle" href="{% url 'doc' data.pk %}">{{data.title|safe}} &nbsp <i class="fas fa-external-link-alt"></i></a><br/><br/> <p> <strong> {{data.sub_title|safe}} </strong> </p> <div … -
How to run my local django server using poetry
I am new to python/django and I am coming into an existing codebase that uses the package manager poetry. My question is simple; how do I start my local django server using poetry run? If not using poetry I understand I can just use python manage.py runserver, but when I run that in my project, I get ImportError: No module named django.core.management. The other most relevant command I ran was poetry run python manage.py runserver, but that yielded ModuleNotFoundError: No module named 'django_q'. I am literally just trying to figure out how to run poetry commands, and in this instance, start my local django server. I am decently lost, so any help with django/poetry would be very helpful. Thank you all in advance! -

Stripe 'card-element' isn't visible (Python/Django)
this is my first time using this site to ask a question. I'd appreciate the help, I have to turn in this bit of the project today as part of my course :( I'm following this tutorial: https://www.youtube.com/watch?v=ncsCnC3Ynlw (chapter: stripe elements) When I visit my checkout page, the card element isn't showing up. I am at the stage around 3:45:00, and when looking at the checkout, the div for the card element is just a thin, empty bar. Could anyone help me find where I made a mistake? I think it might be the connection between the script and the template or just the script itself, but I'm losing my mind trying to figure out what I've done wrong. My views.py: def BasketView(request): carrinho = Carrinho(request) total = str(carrinho.gettotal()) total = total.replace('.', '') total = int(total) stripe.api_key='sk_test_[...]' intent = stripe.PaymentIntent.create( amount=total, currency='brl', metadata={'integration_check': 'accept_a_payment', 'userid': request.user.id} ) return render(request, 'pedido/pedido_novo.html', {'client_secret': intent.client_secret}) My html template: {% load static %} {% block title %}Livraria Aquaflora | Novo Pedido{% endblock %} {% block adtscripts %} <script src="https://js.stripe.com/v3/"></script> <script src="https://unpkg.com/imask@6.0.7/dist/imask.js"></script> <script src="{% static 'js/orderform.js' %}"></script> <script src="{% static 'js/payment.js' %}" data-rel-js></script> {% endblock %} {% block conteudo %} <div class="container-fluid"> <div class="row no-gutter"> … -

Index not being used for django desc
I have a django model with the following indexes: class Meta: indexes = [ models.Index(fields=['-current']), models.Index(fields=['current']), ] These were added and I ran the migration and saw the results: companies/migrations/0294_auto_20220110_1155.py - Create index companies_c_current_f2c815_idx on field(s) -current of model company - Create index companies_c_current_c8bcb7_idx on field(s) current of model company I've found that running a django-rest-framework query with ordering=current is ~5x faster than with ordering=-current. Using PSQL explain I get the following: # explain select * from company order by current desc nulls last limit 100; QUERY PLAN -------------------------------------------------------------------------------------------------------- Limit (cost=41028.75..41040.42 rows=100 width=1223) -> Gather Merge (cost=41028.75..68747.19 rows=237570 width=1223) Workers Planned: 2 -> Sort (cost=40028.73..40325.69 rows=118785 width=1223) Sort Key: current DESC NULLS LAST -> Parallel Seq Scan on companies_company (cost=0.00..35488.85 rows=118785 width=1223) (6 rows) # explain select * from company order by current asc nulls last limit 100; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------------------ Limit (cost=0.42..49.79 rows=100 width=1223) -> Index Scan Backward using companies_c_current_f2c815_idx on companies_company (cost=0.42..140727.06 rows=285084 width=1223) (2 rows) It seems clear from the above that the asc is using the index while the desc is not, which explains the time difference.

How could i redirect a user to a specific primary key
Good evening everyone, I am writing a forum where there are different rooms, in each room a user can leave a comment and also update it as needed. After updating the comment, i want to redirect the user to the same room where this comment was. I tried: 1.Reverse + HTTPResponseRedirect def room(request, pk): room = Room.objects.get(id=pk) room_messages = room.message_set.all().order_by('created') participants = room.participants.all() if request.method == 'POST': message = Message.objects.create( user=request.user, room=room, body=request.POST.get('body') ) room.participants.add(request.user) return redirect('room', pk=room.id) context = {'room': room, 'room_messages': room_messages, 'participants': participants,} return render(request, 'base/room.html', context) @login_required(login_url='login') def updateMessage(request, pk): message = Message.objects.get(id=pk) form = MessageForm(instance=message) if request.user != message.user: return HttpResponse('Unable to edit message') if request.method == 'POST': form = MessageForm(request.POST, instance=message) if form.is_valid(): form.save() return HttpResponseRedirect( reverse( "room", kwargs={ "pk": "13" } ) ) return render(request, 'base/message_form.html',{'obj':message, 'form': form}) but it's working out to return the user only when I manually write the id of the room in which the comment is.

Django - convert datetime string to timezone aware datetime object
So I have a a list of dates and times as a string "2022-01-23 21:30” that I need to import into my Django Application My Django server UTC, however the strings are intended to be UTC+2. So if I import it directly, Django would assume it’s UTC and then the timestamp would saved as 2022-01-23 21:30 (UTC), where in reality it should be converted to 2022-01-23 19:30 (UTC). Is there a specific way I should format it before saving the object in a Django DateTimeField so it will become timezone aware? Thanks in advance. -

CSRF cookie is not set in Django after API call
I have a small Django web app that allows you to log in with a platform using their API. The user is able to log in, but the callback from the log in returns this error: Forbidden (CSRF cookie not set.): /account/platforms/apicallback/ on my server output. I believe that the callback does route to the correct url in my web app, but when it gets to the view associated with it, the CSRF cookie error arises. My request code is below: params = { "app_name": "My App", "scope": scope, "user_id": request.user.id, "return_url": redirect_uri, "callback_url": "https://www.myapp.co.uk/account/platforms/apicallback", "state": {"platform":"api"} } query_string = urlencode(params) url = "%s%s?%s" % (auth_url, query_string) return redirect(url) Here is the urls.py file that contains the callback url: urlpatterns = [ path(r'apicallback/', views.apicallback, name='apicallback'), ] Here is the views.py file with the view for the callback url: @login_required def apicallback(request): consumer_key = request.GET.get('consumer_key') consumer_secret = request.GET.get('consumer_secret') I have got two APIs already working with my web app that both use OAuth2.0, and I haven't come into this issue before. Any ideas on how to fix it without disabling CSRF cookies. Thank you -
Can not use POST method with Django 4 Rest Framework
I'm having an issue with a new django 4 app not processing or not allowing POST method. I used to bypass this in Django version 3 by adding a trailing slash "/" to the end of url in Postman API Tester like http://127.0.0.1:8000/api/didipay/ instead of http://127.0.0.1:8000/api/didipay . But now in my Django 4 API I completed the url with the slash but POST method is still not processing the data. It gives me a "500 internal server error" and I don't understand where it is coming from. The GET method is rather giving an empty array which is normal because I've not inserted any data yet in the database. I'm using venv, Django 4 Rest framework, serializer, viewSet and these is my models and API urls configurations: //Serialize.py from rest_framework.decorators import permission_classes from didipay_app.models import Didipay_app from rest_framework import viewsets, permissions from .serializers import Didipay_appSerializer class Didipay_appViewSet(viewsets.ModelViewSet): queryset = Didipay_app.objects.all() permission_classes = [ permissions.AllowAny ] serializer_class = Didipay_appSerializer // Project folder's urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path('', include('didipay_app.urls')), ] // App folder's urls.py from rest_framework import routers, urlpatterns from .api import Didipay_appViewSet router = routers.DefaultRouter() router.register('api/didipay', Didipay_appViewSet, 'didipay') urlpatterns = router.urls The … -
Python Paramiko "exec_command" does not execute - Django
I am facing an issue with the Python Paramiko library in my Django Application This is a function I have written to create an SFTP connection: def createSFTPConnection(request,temp_pwd): ssh=paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) user = User.objects.get(username=request.user) ssh.connect(hostname=temp_host,username=user.username,password=temp_pwd,port=22) sftp_client=ssh.open_sftp() return ssh,user,sftp_client This just returns me the variable for ssh, the username, and sftp_client Then I execute a command on the remote server using this code - ssh,user,sftp_client=createSFTPConnection(request,temp_pwd) # passes the password on that server for the user for creating the connection cmd_to_execute="(cd "+temporary_path+"; sh temp.sh"+" "+var1+" "+var2+")" # executing a shell script by passing it 2 variables stdin, stdout, stderr = ssh.exec_command(cmd_to_execute) # actual call print("stderr: ", stderr.readlines()) print("pwd: ", stdout.readlines()) Now, this code works fine and executes the script "temp.sh" on the remote server, but it takes a lot of time as I am returning stdin, stdout and stderr and printing them on the console But, since I don't want that I removed the readlines() calls from there making my code look like this - cmd_to_execute="(cd "+temporary_path+"; sh temp.sh"+" "+var1+" "+var2+")" stdin, stdout, stderr = ssh.exec_command(cmd_to_execute) # actual call But for some reason, this code just doesn't execute on the remote server after removing the readlines() calls Thus, making me think that exec_command …
