AccessDeniedError at /auth/convert-token (access_denied) Your credentials aren't allowed <oauthlib.Request SANITIZED>
I am using Django 4.0 with python 3.9 and I installed drf-social-oauth2 in my app. I was using the now depreciated gapi Oauth2 for google login and it worked fine. Then I started getting warnings in my console that it'll not be in use for some time to come so I changed to the new google Identity Service(gsi client). What I used to get from gapi was an access_token which I use to verify users on my backend. now I get a credential jwt which I'm supposed to decode to get user details. when I send this code to the /auth/convert-token/ end point, I get AccessDeniedError at /auth/convert-token (access_denied) Your credentials aren't allowed <oauthlib.Request SANITIZED> all my details are correct and I'm stuck. Tested this using vscode thunder client. -
How do I edit my serializer create() method to make relationship to nested object in Django REST Framework?
In my app, Groups are created by Users class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ["user_id", "username"] class GroupSerializer(serializers.ModelSerializer): owner = UserSerializer() class Meta: model = Group fields = ["name", "picture_url", "owner", "members"] def create(self, validated_data): owner_data = validated_data.pop("owner") user = User.objects.filter(user_id=owner_data.get("user_id")) instance = Group.objects.create(**validated_data) instance.owner = user instance.save return instance I'm trying to have it so that I can create a Group object, which can only have an existing User as its owner, but somehow when I post the following: "owner": { "user_id":6 }, "picture_url":"nothing", "name":"jazz club" } It returns this: { "owner": { "user_id": [ "user with this user id already exists." ], "username": [ "This field is required." ] } } For context, my post method looks like this: def post(self, request): new_group = request.data new_group["members"] = [] serializer = self.serializer_class(data=new_group) serializer.is_valid(raise_exception=True) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) And my models look like this: class User(models.Model): id = models.BigAutoField(primary_key=True, unique=True) user_id = models.BigIntegerField(unique=True) username = models.CharField(max_length=100) class Group(models.Model): name = models.CharField(max_length=255, unique=True) picture_url = models.CharField(max_length=255) owner = models.ForeignKey( User, on_delete=models.CASCADE, related_name="owned_groups", blank=True, ) members = models.ManyToManyField(User, related_name="groups", blank=True) What do I need to change to make this work? I've tried a lot of different stuff. -

Correct way of writing a filter query on a geodjango model (finding out if a multipolygon field contains a point)
I am new to geodjango and am trying to build an application after going through the tutorial. So, I have this model: from django.contrib.gis.db import models class CountryBorder(models.Model): f_code = models.CharField(max_length=5) name = models.CharField(max_length=254) .... .... #the multipolygonfield on which I want to perform lookup geom = models.MultiPolygonField(srid=4326) def __str__(self): return self.name and I am trying to find the model instance which contains (the model.geom field contains) a point. I tried doing that as described in the documentation: from app_name.models import CountryBorder from django.contrib.gis.geos import Point pnt = Point(23.1827, 75.7682) CountryBorder.objects.get(geom_contains=pnt) But I get the following error message: django.core.exceptions.FieldError: Cannot resolve keyword 'geom_contains' into field. Choices are: f_code, geom,name..... Am I missing something? -

Django's prefetch_related method asynchronously blocking HTTP response
Does Django's prefetch_related method block the thread returning the http response in some sort of async way? def test_view(request): rows = SomeModel.objects.prefetch_related('some_m2m_field') num_rows = len(rows) print(num_rows) return JsonResponse({'num_rows':num_rows}) I know that the correct way to get the number of rows is .count(), I'm using len() here as a simple way to force evaluation of the queryset. In reality, I'm not even interested in the number of rows, just doing this as a simplification so that we don't have to get into my business logic. So, here's the goofy thing, when running on a DB with ~25k rows the above code will print the number to the terminal in just a second or two, but it will take over a minute to return the JSON to the browser!? When you remove the prefetch_related, everything happens nice and snappy, but I need that prefetch_related for my actual business logic, which has been omitted here for simplicity. I understand that the prefetch is going to make the query slower, but something else has to be going on here right? if it were just a slow query the print statement would take just as long as the JsonResponse? -

Azure deployed django app not displaying media files on Vuejs frontend in prooduction
These are the packages that I am using Django==3.2 django-storages==1.12.3 I am trying to deploy a django REST API with Vuejs frontend on azure. This is my directory structure for the django API.

Long running Celery task result in mysql 104 Connection reset by peer
At my Django application, I use celery to process very long-running conversion tasks (video, audio and picture encoding). In general everything is working as expected, but sometimes a task takes really long time to complete (talking 6 hrs. Or more here). At the very end of each of these conversion tasks, an update operation is trigger against my database: Files.objects.filter(pk=files_obj).update(... And exactly this is the point where my celery task breaks with this message: django.db.utils.OperationalError: (2006, "MySQL server has gone away (ConnectionResetError(104, 'Connection reset by peer'))") The full trace can be found here: https://pastebin.com/qKB5KdpR Currently, my settings.py for Database connections looks like this: import pymysql pymysql.install_as_MySQLdb() ... # MySQL DATABASES = { 'default': { 'ENGINE': 'django_prometheus.db.backends.mysql', # 'ATOMIC_REQUESTS': True, 'STORAGE_ENGINE': 'InnoDB', 'CONN_MAX_AGE': 600, 'OPTIONS': { 'init_command': 'SET innodb_strict_mode=1', 'connect_timeout': 600, 'charset': 'utf8', }, 'NAME': env.str('MYSQL_DATABASE'), 'USER': env.str('MYSQL_USER'), 'PASSWORD': env.str('MYSQL_PASSWORD'), 'HOST': env.str('MYSQL_HOST'), 'PORT': env.str('MYSQL_PORT'), } } DEFAULT_AUTO_FIELD = 'django.db.models.AutoField' ... Enlarging CONN_MAX_AGE or connect_timeout does not make much sense to me here as tasks that are running for just 3 or 4 hrs. Are processed fine without this behavior. Currently, my guess is that this behavior is pymysql specific. Is there maybe a default timeout? Thanks in advance. -

What's the most efficient way to retrieve django queryset with the hightest number of posts for a related name?
I'm currently working on a website where advertisements will be posted to display vehicles for sale and rent. I would like to retrieve a queryset that highlights only one car brand (i.e. Audi) which has the highest number of posts for the respective model. Example: Displaying the Audi brand because it has the highest number of related posts. My question is, what's the most efficient way of doing this? I've done some work here but I'm pretty sure this is not the most efficient way. What I have is the following: # Algorithm that is currently retrieving the name of the brand and the number of related posts it has. def top_brand_ads(): queryset = Advertisement.objects.filter(status__iexact="Published", owner__payment_made="True").order_by('-publish', 'name') result = {} for ad in queryset: # Try to update an existing key-value pair try: count = result[ad.brand.name.title()] result[ad.brand.name.title()] = count + 1 except KeyError: # If the key doesn't exist then create it result[ad.brand.name.title()] = 1 # Getting the brand with the highest number of posts from the result dictionary top_brand = max(result, key=lambda x: result[x]) # Returns for i.e. (Mercedes Benz) context = { top_brand: result[top_brand] # Retrieving the value for the top_brand from the result dict. } print(context) # … -

Django: Storing static folder on S3 bucket leading to the css, and js files not working
I have js, images, and CSS folders inside the static folder. They are stored in the S3 bucket. Unless I give public access, my app cannot load the CSS files, images, and javascript files. My app relies on the js files (jQuery) for all interactions (API calls - for Ajax). What specific permission would I have to set on the S3 bucket to allow my app to read or execute the js files, but not allow anyone to download or view them (when they put the fully qualified URL on the browser)?
