How to create a service from a function?
I want to create a service using Django Rest API. I have a function. The result of this function should return 2 values and I should return these values in JSON API format. The function will work like this. I will receive the features_list as a parameter and I will use it to create a result and display it as a service in json format in def prediction function. I created a sample API (I guess) it is class PredictionSet in my views but I actually want to make service the def prediction function in my views. I cannot understand how to apply it.

Django-channels and Firefox connection issue

How to use Django function based view to update a model?
I used a class based view to update a user profile using this code class EditProfileViewClass(generic.UpdateView): model = UserProfile fields = ['bio', 'profile pic'] template_name = 'users/update.html' success_url = reverse_lazy('home') path('profile/<int:pk>/update', EditProfileViewClass.as_view(), name="profile"), <a href="{% url 'profile' user.id %}">Your Profile</a> the issue right now is, Instead of having the url like the one above, I want it to be like path('profile/<str:username>/update', EditProfileViewClass.as_view(), name="profile"), but unfortunately I get an attribute error saying: Generic detail view EditProfileView must be called with either an object pk or a slug in the URLconf. So I tried making a function based view so I can get the "username" from the url, doing that didn't allow me to get the form I needed to update the specific username. Any help would be great. Thanks. -

Is there a way to keep alive request longer than 60s in EC2 instance?
Hello everyone I've been trying to execute our django app on amazon aws ec2 instance. Everything works fine except for requests longer than 60s. Those requests automatically get 504 Gateway Time-out. I configured all needed ports in Security Groups for my EC2 instance. We are using nginx and my nginx.conf looks like: user nginx; worker_processes auto; error_log /var/log/nginx/error.log notice; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 3600s; client_max_body_size 500M; client_body_timeout 86400s; client_header_timeout 86400s; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; proxy_connect_timeout 86400s; proxy_send_timeout 86400s; proxy_read_timeout 86400s; send_timeout 86400s; #gzip on; include /etc/nginx/conf.d/*.conf; } I tried to play with keepalive_timeout as many posts suggest but it's not working. There are also a lot of posts mentioning load balancer configuration but I'm not even using load balancer so this should not be related to it.

How to convert json to form in Django?
I'm developing a Django project, and the team want to seperate the front-end and the back-ed, so I'm using Django to develop api. The format of the data transmitting is json. However, I want to use the defalt user package (django.contrib.auth), and I have to use Form.

Reverse look-up with related name

That is, my goal is to do something like Person.objects.filter(marriage__id=32). I understand that the related name has some role there, but for example Person.objects.filter(person_2__marriage__id=32) doesn't seem to work either. Thank you! -
Weird behavior when accessing request.user in django
I have a simple view which requires a user to be logged in AND belongs to a specific group as the following class IndexView(LoginRequiredMixin, UserPassesTestMixin, generics.GenericAPIView): serializer_class = IndexSerializer def test_func(self): print(self.request.user) // User object return self.request.user.groups.filter(name='Poster').exists() def get(self, request, *args, **kwargs): print(self.request.user) // AnonymousUser print(request.user) // Anonymous User return HttpResponse('Welcome') The thing is when I print the user inside the get method it returns AnonymousUser but it returns a User object inside the test_func method. I am clueless of why this is happening so any help would be appreciated. -
REST Api Django - create new model-object and add currently logged in user to it
I have an endpoint, where a currently logged in user can create an object called 'project' . I want to show the user all of his own projects, so when he creates a new one, I want the user to be automatically added to the projects user fields. How would I achieve that? Both the user and the Project objects do have an ID, so I would like to have an own model wich combines those two. My idea was to create a new view wich takes a userID and a projectID and puts them together as ManyToMany relationship. Can I somehow call the view right inside the 'create project' view without the need of a new POST ? I want to be able to use the view at an other point as well, thats why I want to split this. my current model looks like this models.py class Project(models.Model): id = models.AutoField(db_column = 'db_ID', primary_key = True) name = models.CharField(max_length=500, default = None) descriptor = models.CharField(max_length = 1000, default = None) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: db_table = 'Projects' def __str__(self): return self.name views.py class ProjectView( APIView, ): def post(self, request): serializer = ProjectSerializer(data = request.data) … -

Twilio Voice Gather + Django Regex Validation
How do I use regular expressions to validate user input collected via dtmf? For example: I want to apply validation on multiple views within the same views.py. If user input passes validation then redirect to the next view. If user input fails validation then use the verb to give an error message and redirect to current view so that they can try again. Example: Please press 123 User presses 384 Input is checked against regex and it fails validation Say: I'm sorry, but that is incorrect. redirect to current view, so user may retry Please press 123.
