Redis-RQ not executing jobs
I have a question but it turns out I have similar problems to other Github threads that haven't been resolved yet, might as well ask it here. I am running Django and is using redis-rq to execute background jobs. Unfortunately, it doesn't execute jobs from the default queue. I have already tried to rename it but no progress so far. Have you guys had this similar event before, and how did you resolve it? Thanks! -
Proper directory structure for app versioning (Django)
I am currently starting work on a existing Django Project, and I need to make changes to the existing APIs. However, I can't change the existing code since old apps and sites have been using it, which might take a lot of time to change the structure, and might break current dependencies for those. So, for now, as asked, I need to maintain separate directories to change/review the existing code and achieve a versioning-like structure for Django apps. What might be the best way/structure to achieve this? The current structure is simple as given by django-admin startproject project_dir |___project_name_dir |___settings.py ... |___app_1_dir |___ __init__.py |___ views.py, serializers.py ... |___app_2_dir ... So, I need to like create versioning type structure for app_1 here. What might be the best approach to do that? -
Django Rest Framework custom throttling classes not working
I am having issues with setting up custom throttling using the django-restframework for django. I made the following views.py class which contains a view with this custom throttle: from .custom_throttles import * @api_view(('GET',)) @throttle_classes([LowLevelThrottle]) def home_stats(request): token = request.data['token'] if token == os.environ['api_token']: content = { 'users' : len(Profile.objects.all()), 'posts' : len(Post.objects.all()), 'reactions' : len(PostReaction.objects.all()) } return Response(json.dumps(content), status=status.HTTP_200_OK) else: content = { 'error' : 'invalid token' } return Response(json.dumps(content), status=status.HTTP_401_UNAUTHORIZED) This custom throttle is imported from custom_throttles.py which looks as following: from rest_framework import throttling class LowLevelThrottle(throttling.AnonRateThrottle): scope = 'll' def allow_request(self, request, view): if request.method == "GET": return True return super().allow_request(request, view) And last but not least, this is how I have some settings in my settings.py file setup: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', } } REST_FRAMEWORK = { 'DEFAULT_THROTTLE_CLASSES': [ 'rest_framework.throttling.AnonRateThrottle', 'django_project.custom_throttles.LowLevelThrottle' ], 'DEFAULT_THROTTLE_RATES': { 'll': '1/second', } } I also have the following logs I can provide clearly showing how multiple requests were made within this 1 second time frame.

How to use Django with a legacy mysql 5.7 database (troubles with mysqlclient version)
I started a new Django project, but it supposed to be working with a legacy MySQL 5.7 database. For now, I have Django project, with specified database in settings.py and mysqlclient installed. First thing i tried was python manage.py inspectdb --database dbname but I git this error: MySQLdb.OperationalError: (1043, 'Bad handshake') I already realized that this is because I have mysqlconnector for version 8.0, and it's not compatible with mysql 5.7. I also found out that when installing mysqlconnector, its version depends on what i have in mysql_config. If I type mysql_config --version I get 8.0.30 And I cannot understand why, because if I run sudo dpkg-reconfigure mysql-apt-config It says that I have currently selected mysql-5.7. What actually is mysql_config and why it's configured to a different version? How can I switch it to 5.7 and have right version of mysqlclient installed? Or are there any other ways to make mysql 5.7 and my Django project work together? -

serializer.data and serializer.validated_data is blank when a serializer is initialized by dictionary
I am building an app using django and drf. While testing a serializer, I found the serializer could not save data to database because of null constraints. Below is the test code, serializer and model. location_serializer_data: LocationDict = { 'address': 'address', 'latitude': 11.1, 'longitude': 22.2, } @pytest.mark.django_db def test_deserializing(self): serializer = LocationSerializer(data=location_serializer_data) serializer.is_valid() new_location = serializer.save() # < where the test explodes Here is the error message django.db.utils.IntegrityError: NOT NULL constraint failed: locations_location.latitude I found that serializer.initial_data gets the data appropriately, but after serializer.is_valid(), two of serializer.data, serializer.validated_data become blank dict. I searched a bit but I found no clue of what was causing this. -

Django formsets not saving all forms to the database
I have a formset to render multiple forms at once. By default only two forms are rendered. Using JavaScript, I'm adding another two forms to the formset, so the total number of forms is now four.

How to merge two models inherited from Django into one serializer
In Django, is there a way to combine two models that inherit the same class into one serializer? from django.db.models import Model class A(Model): a = IntegerField(...) class B(A): # There may or may not be such a thing as class C. class C(A): # There may or may not be such a thing as class B.

Time Zones and Filters in Django Rest Framework
We have a game where we keep track of daily, weekly and monthly leaderboards. Most of the users are in the US, so we're trying to have the daily/weekly/monthly charts update around a US timezone. So the setup we have is pretty straight forward. # models.py class PackGameSavedPack(auto_prefetch.Model): date = models.DateTimeField(null=True, blank=True) user_name = models.CharField(max_length=120, null=True) pack_score = models.IntegerField(null=True) # save_pack.py def pack_game_save_pack(user_id, user_name, pack_score=None): pack = PackGameSavedPack.objects.create( user_id=user_id, date=timezone.now(), user_name=user_name, pack_score=pack_score, ) #views.py class PackGameFilter(django_filters.FilterSet): user_id = CharInFilter(field_name='user_id', lookup_expr='in') date_range = DateRangeFilter(field_name='date') For the most part, this works great - except its saving all of the dates in the UTC (O offset) format. We set the USE_TZ and TIME_ZONE parameters in the settings.py file, however, this didn't seem t change anything. USE_TZ = True TIME_ZONE = "America/Los_Angeles"` I know I can adjust the dates/times at the serializer level, however, that doesn't help with the DateRangeFilter as it is using the UTC (0 offset) timezone. How can I get the DateRangeFilter using the TIME_ZONE or whats a better way to approach this?
