Django Rest Framework: use create with primary key in URL
I can't apply the @action decorator to create function within a standard views.Viewset subclass. @action(detail=True) # This fails. def create(self, request, pk=None): return Response(etc...) On other methods, adding that decorator allows me to create URLs easily with <pk> within the URL. For example, I can send a POST request to http://main_url.com/do_something_to_user_with_id/7/, with do_something_to_user_with_id being some random function within the viewset and 7 being the user id/primary key. Is there any way I can do this with create? -

How do link a file user uploaded to Database?
This is how I was saving user uploaded Files: f = request.FILES[x] s = File(file=f, user=curUser) s.save() This worked great but it took a lot of bandwidth on my server so I decided to use pre-signed urls. Now users upload directly to s3 Bucket, however it's not linked to Database. I tried this which runs after user successfully uploads to S3: f = default_storage.open(userID + "/" + fileName) curUser = User.objects.get(userID=userID) s = File(file=f, user=curUser) s.save() f.close() However, this is just creating a new folder on users directory and uploading it there. my Models: class User(models.Model): userID = models.CharField(max_length=101,primary_key=True) class File(models.Model): user = models.ForeignKey(to=User, on_delete=models.CASCADE) file = models.FileField(max_length=255, upload_to=user_directory_path) def user_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> path = instance.user.userID + "/" + filename return path -

Delete User from db Django Rest_framework View function

Here is my Views: class RetrieveUsersView(generics.ListCreateAPIView): """Retrieves all Users""" serializer_class = UserSerializer authentication_classes = (authentication.TokenAuthentication,) permission_classes = (permissions.IsAuthenticated,) queryset = get_user_model().objects.all() Here is my Serializer: class UserSerializer(serializers.ModelSerializer): """Serializer for the users object""" class Meta: model = get_user_model() fields = ('email', 'password', 'name') extra_kwargs = {'password': {'write_only': True, 'min_length': 5}} def create(self, validated_data): """Create a new user with encrypted password and return it""" return get_user_model().objects.create_user(**validated_data) def update(self, instance, validated_data): """Update a user, setting the password correctly and return it""" password = validated_data.pop('password', None) user = super().update(instance, validated_data) if password: user.set_password(password) user.save() return user Here is my Urls: urlpatterns = [ path('create/', views.CreateUserView.as_view(), name='create'), path('token/', views.CreateTokenView.as_view(), name='token'), path('me/', views.ManageUserView.as_view(), name='me'), path('all_users/', views.RetrieveUsersView.as_view(), name='all_users') ] From my understanding Django rest has built in classes that allow DELETE requests. However when I view the api on the local host I am only able to view all the registered users based on my RetrieveUsersView class. I would expect the url to be something like /api/users/all_users/1 Then delete that one. I am bit confused on how to get that functionality. -

Posting to DB using django serializers
I am learning django rest framework and I seem to have a problem with my ForeignKey models and serializers. I have two models and two serializers Models class Clients(models.Model): client_public_key = models.CharField(max_length=100, default=generate_client_public_key, unique=True) client_name = models.CharField(max_length=100, unique=True, null=False) client_name_abbr = models.CharField(max_length=100, unique=True, null=True) created_by = models.IntegerField(default=1, null=False) #Has to be changed to foreign key created_at = models.DateTimeField(auto_now_add=True, null=False) class Meta: ordering = ["client_name"] class Users(models.Model): client = models.ForeignKey(Clients, on_delete=models.CASCADE) user_public_key = models.CharField(max_length=100, null=False, default=generate_client_public_key, unique=True) first_name = models.CharField(max_length=100, null=False) last_name = models.CharField(max_length=100, null=False) email = models.CharField(max_length=100, null=False, unique=True) cell = models.IntegerField( null=True) support_department = models.CharField(max_length=50, null=False) password = models.CharField(max_length=150, null=False) user_status = models.IntegerField(null=False) password_changed = models.IntegerField(default=0, null=False) last_login = models.DateTimeField(null=True) created_by = models.IntegerField(default=1, null=False) #Has to be changed to foreign key created_at = models.DateTimeField(auto_now_add=True, null=False) class Meta: ordering = ["first_name"] Serializers class ClientSerializer(serializers.ModelSerializer): class Meta: model = Clients fields = '__all__' read_only_fields = ('id','client_public_key') class UserSerializer(serializers.ModelSerializer): # client = ClientSerializer() # client = serializers.StringRelatedField() class Meta: model = Users depth = 1 fields = '__all__' read_only_fields = ('id','user_public_key') The problem is when I add depth=1 in my UserSerializer I get (1048, "Column 'client_id' cannot be null") error when posting data. What am I doing wrong? -

Django + Gunicorn + Kubernetes: Website down few minutes on new deployment
I am having this issue with Django + Gunicorn + Kubernetes. When I deploy a new release to Kubernetes, 2 containers start up with my current image. Once Kubernetes registers them as ready, which they are since the logs show that gunicorn is receiveing requests, the website is down for several minutes. It just times out for roughly 7-10 minutes, until it's fully available again: The logs show requests, that are coming in and returning 200 responses, but when I try to open the website through the browser, it times out. Also health checkers like AWS Route53 notify me, that the website is not reachable for a few minutes. I have tried to many things, playing around with gunicorn workers/threads, etc. But I just can't get it working to switch to a new deployment without downtime. Here are my configurations (just the parts I think are relevant): Requirements django-cms==3.7.4 # https://pypi.org/project/django-cms/ django==2.2.16 # https://pypi.org/project/Django/ gevent==20.9.0 # https://pypi.org/project/gevent/ gunicorn==20.0.4 # https://pypi.org/project/gunicorn/ Gunicorn config /usr/local/bin/gunicorn config.wsgi \ -b 0.0.0.0:5000 \ -w 1 \ --threads 3 \ --timeout 300 \ --graceful-timeout 300 \ --chdir=/app \ --access-logfile - Kubernetes Config livenessProbe: path: "/health/" initialDelaySeconds: 60 timeoutSeconds: 600 scheme: "HTTP" probeType: "httpGet" readinessProbe: path: "/health/" … -

django sessions remember me
I am new to django and have not found a question corresponding to my entry level. And I just can't figure out how to work with sessions. I want to make a checkbox on login to remember me. After I registered in settings SESSION_EXPIRE_AT_BROWSER_CLOSE = True, you need to enter your username and password after closing the browser. How do I change this parameter using the "remember me" checkbox? Thank you views.py def login(request): if request.method == 'POST': username = request.POST['username'] password = request.POST['password'] user = auth.authenticate(username=username, password=password) if user is not None: auth.login(request, user) return redirect('/') else: messages.info(request, 'invalid credentials') return redirect('login') else: return render(request, 'prof/login.html') login.html <body> <div class="text-center mt-5"> <form style="max-width: 480px; margin: auto" method="post"> {% csrf_token %} <img src="https://logodix.com/logo/1713894.jpg" alt="" width="120" height="90" class="d-inline-block mt-4 mb-4" /> <p class="hint-text mb-3">Please sign in</p> <label class="sr-only" for="username"></label> <input type="login" name="username" class="form-control" placeholder="username" required autofocus /> <label for="password" class="sr-only"></label> <input type="password" name="password" class="form-control mt-2" placeholder="password" /> <div class="checkbox"> <label for="checkbox"> <input type="checkbox" name="checkbox" value="remember-me" /> remember me </label> </div> <div class="d-grid gap-2 mt-4"> <input type="Submit" class="btn btn-primary" value="sign in" /> </div> </form> <div class="messages"> {% for message in messages %} <h3>{{message}}</h3> {% endfor %} </div>
