How to properly catch POST request in a Django serializer when using the JSON Web token authentication?
I customized the AUTH_USER_MODEL variable in settings.py to implement JSON Web Token authentication in Django, and everything works perfectly to login as superuser in the admin section. However, when I try to register a new user with the REST API, the line request.data.get('user', {}) in the serializer returns an empty dictionary, so I need to convert the object of type QueryDict into a Dict. Then I need to unlist the dictionary's values to finally have valid data. I'm afraid there is something wrong in my code, what is the proper way to do that ? I followed the tutorial from Thinkster here. views.py from rest_framework import status from rest_framework.permissions import AllowAny from rest_framework.response import Response from rest_framework.views import APIView from authentication.serializers import RegistrationSerializer class RegistrationAPIView(APIView): permission_classes = (AllowAny,) serializer_class = RegistrationSerializer def post(self, request): # user = request.data.get('user', {}) # <- returns {} user = dict(request.data) user = {k:v[0] for k,v in user.items()} serializer = self.serializer_class(data=user) serializer.is_valid(raise_exception=True) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) settings.py AUTH_USER_MODEL = 'authentication.User' AUTHENTICATION_BACKENDS = [ 'graphql_jwt.backends.JSONWebTokenBackend', 'django.contrib.auth.backends.ModelBackend', ] GRAPHQL_JWT = { "JWT_ALLOW_ARGUMENT": True, } REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'authentication.backends.JWTAuthentication', ] } -
How do I view movies in descending order of average score? django
What we want to achieve. I want to display the score (stars) of a movie in descending order. Present condition The tmdb API is used to retrieve movie information. And the model movie and TV have only ID and stars(score). From here, only those with stars are returned to html. I want to ask a question. And if score is selected, how can I make it appear in descending score order? data = requests.get (f "https://api.themoviedb.org/3/tv/{tv_id}?api_key={TMDB_API_KEY}&language=en-US"). Now you can get the information of tv. def index(request): movie = reversed(Movie.objects.order_by('stars')) tv = reversed(TV.objects.order_by('stars')) context = { "movie": movie, "tv" : tv, } return render(request, 'Movie/index.html', context) class Movie(models.Model): id = models.CharField(primary_key=True, editable=False, validators=[alphanumeric],max_length = 9999) stars = models.FloatField( blank=False, null=False, default=0, validators=[MinValueValidator(0.0), MaxValueValidator(10.0)] ) def get_comments(self): return Comment_movie.objects.filter(movie_id=self.id) def average_stars(self): comments = self.get_comments() n_comments = comments.count() if n_comments: self.stars = sum([comment.stars for comment in comments]) / n_comments else: self.stars = 0 return self.stars class TV(models.Model): id = models.CharField(primary_key=True, editable=False, validators=[alphanumeric],max_length = 9999) stars = models.FloatField( blank=False, null=False, default=0, validators=[MinValueValidator(0.0), MaxValueValidator(10.0)] ) def get_comments(self): return Comment_tv.objects.filter(tv_id=self.id) def average_stars(self): comments = self.get_comments() n_comments = comments.count() if n_comments: self.stars = sum([comment.stars for comment in comments]) / n_comments else: self.stars = 0 return self.stars class … -

CSS file references a file which could not be found. (Fieldsets forms and Heroku)
I am using fieldsets for my django forms. Everything works fine on local. I wanted to uploaded onto Heroku and started running into problem. When running "python manage.py collectstatic", I am getting the following error: The CSS file 'forms_fieldset\css\main.css' references a file which could not be found: forms_fieldset/img/sorting-icons.svg The message is correct. The file forms_fieldset/img/sorting-icons.svg is not mentioned in main.css. I suppose there is two questions: How does it know a file does not exist, if it actually not mentioned anywhere? How and where can I add this file?

Customizing authentication backend for multi users in Django
So my question is that you have a custom user 'Account' and I'm trying to use Loginview but with only one specific backend but the class does not care about the value passed. from django.contrib.auth import views as auth_views from .lists import ProjectCreateView , ProjectUpdateView , ProjectDeleteView class ClientLogin(auth_views.Loginview): def form_valid(self, form): """Security check complete.

spotify api "player/currently-playing" enpoint is not return currently playing song data

Restricting User to have one one-to-one relationship with any one of the given models Django
I am having two model classes named as Leader and Member, both have a OnetoOne relationship with User, as you can see below: from django.db import models from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.DO_NOTHING) # Abstract model class for common fields in Leader and Member class Meta: abstract = True class Leader(Profile): # attributes # def save(self) -> None: # if Member.objects.filter(user=self.user).first() == None: # return super().save() # else: # raise ValidationError("User is already a member, migrate it to make it leader.") class Member(Profile): # attributes But if a user is already having a relation with anyone, among both of them, then it should not be allowed to have a relation with the other one. For example: If a user1 is referenced by Leader model, then it is not allowed to be referenced by Member model, if needed there should be a process by which we can remove and add user from Leader model to Member model, i.e. transferring Profile abstract model data from Leader model to Member model and receiving remaining data manually or vica versa.

How to save media files to Heroku local storage with Django?
Im having a Django REST app with React for client. Im recording a file with React and sending in to Django. When i save it i modify it with ffmpeg and save it again in the same folder with a new name, the ffmpeg command looks like this: os.system(f"ffmpeg -i {audio_path} -ac 1 -ar 16000 {target_path}") Because i need a path for my audio both for opening and saving, i can't use cloud stores like "Bucket S3, Cloudinary etc.". And the fact that im using it only for a few seconds and then deleting it makes Heroku (the app is deployed there) the perfect place to save it non-persistent. The problem is that the file isn't getting saved in my library with media files. It saves in the postgre db but doesn't in my filesystem and when i try to access it my program returns that there isn't a file with that name.
