django-waffle does not show proper flag status on waffle_status endpoint
I have created this flag: I'm trying to get the flag status using the waffle_status endpoint, but no matter if the user is logged or not I get the same response: { "flags": { "test_flag": { "is_active": false, "last_modified": "2023-12-21T16:03:38.922Z" } }, "switches": {}, "samples": {} } It is supposed that I have to get this flag as True for the user farid, the one with id 1, isn't? I made this exercise using django 4, django-waffle 4.1.0, and I have made this configs on settings.py . . . INSTALLED_APPS = [ 'django.contrib.admin', 'rest_framework', 'rest_framework.authtoken', 'django.contrib.auth', 'waffle', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'exammple' ] . . .

REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ] } . . . and in project's url.py file urlpatterns = [ path('admin/', admin.site.urls), path('api/v1/token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('api/v1/token/refresh/', TokenRefreshView.as_view(), name='token_refresh'), path( 'api/v1/', include( [ path('', include(example_urls)) ] ) ), path('waffle/', include('waffle.urls')), ] Is this a bug/missing feature on waffle? or I'm missing some config in somewhere? P.S. The purpose of this is that I have to give this flag status to a FrontEnd app to show or hide some visual components depending … -
Django - Filter by Foreign Key
I have 2 models class Project(models.Model): name = models.TextField(max_length=150) class Asset(models.Model): name = models.TextField(max_length=150) project = models.ForeignKey('Project', related_name='ass') I can use this command to get a Project with all its Assets, it's cool. proj = Project.objects.get(pk='QQ') But I just want to get a Project with a specific Asset, this is my command: proj = Project.objects.get(pk='QQ', ass__pk=50) But it still returns all Assets. Then I turn on the SQL debug mode and find Django runs 2 SQLs. It executes 'SELECT project.* FROM project INNER JOIN asset ON ... WHERE project.pk='QQ' AND asset.pk=50 It executes 'SELECT asset.* FROM asset WHERE asset.project = 'QQ' I think the 1st SQL is enough, I have no idea why 2nd SQL is executed. I use Django 4.2 with Python 3.8.10, can anybody help it? -

Django Rest Framework Token Auth > Remove user foreign Key from POSTs while keeping it for GETs
I'm struggling to make this work. I have the following model: class Message(models.Model): text = models.CharField(max_length=500) date = models.DateTimeField("date published") user = models.ForeignKey(User, on_delete=models.CASCADE) room = models.ForeignKey(Room, on_delete=models.CASCADE) def __str__(self): return self.text Here is my serializer: class MessageSerializer(serializers.HyperlinkedModelSerializer): user = UserSerializer() class Meta: model = Message fields = ['id', 'text', 'date', 'user', 'room'] I've changed the serializer to have the user "expanded" when I retrieve my Message list with a GET request. So what I hoping to achieve - with my token authentication - is to avoid passing the user in my POST request. As I pass the token for authentication, there should be a way to retrieve the user with it. Here are my ViewSets: class UserViewSet(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = UserSerializer class MessageViewSet(viewsets.ModelViewSet): serializer_class = MessageSerializer def get_queryset(self): authentication_classes = [] room_id = self.request.query_params.get('room_id') return Message.objects.filter(room=room_id) My settings: REST_FRAMEWORK = { # Use Django's standard `django.contrib.auth` permissions, # or allow read-only access for unauthenticated users. 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ], 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.BasicAuthentication', 'rest_framework.authentication.TokenAuthentication', ] } How can I do this? Thanks! -
Python - Django Beginner - Form to submit data to my database - Cannot find answer
I am quite new to Python - Django and I have only spent my spare time learning. I have successfully created a user registration form that posts data to my postgresql database: My code looks like this: Views: def signupr(request): if request.method == 'POST': username = request.POST\['username'\] email = request.POST\['email'\] password = request.POST\['password'\] password2 = request.POST\['password2'\] if password == password2: if User.objects.filter(email=email).exists(): messages.info(request, 'Email Already Exists') return redirect('registration') elif User.objects.filter(username=username).exists(): messages.info(request, 'Username Already Exists') return redirect('registration') else: user = User.objects.create_user(username=username, email=email, password=password) user.save(); return redirect('dashboard') else: messages.info(request, 'Passwords Do Not Match') return redirect('registration') else: return render(request, 'registration_form.html') (very basic but it works) I have a form that successfully creates users to a database. Note that Django understands "User.objects.create_user" and creates a new user row for me. The problem comes in when I try to use the same logic to create a property listing for example I have a basic version of my model called "Properties" : ` class Properties(models.Model): title = models.CharField(max_length=100, default='Not Set') feat_image = models.ImageField(upload_to='images', default='/images/scrolltop.png') gallery_images = models.ImageField(upload_to='images', default=False) external_property_listing_url = models.CharField(max_length=255) property_rules = models.CharField(max_length=500) ` Now when I try to create this in my views: def addpropertylisting(request): if request.method == 'POST': title = request.POST['title'] property = … -

Please explain me this. I cant understand it
A common gotcha to be aware of is that the field type dictates how to use these values. Whenever you have a string-based field like CharField or TextField, setting both null and blank as we’ve done will result in two possible values for “no data” in the database. Which is a bad idea. The Django convention is instead to use the empty string "", not NULL I cant understand what will go wrong for charfiel and textfield? -

Django CORS cannot set cookie in HTTP
Premise I wanna use Django sessionid feature to identify which user was sending request. Therefore I need the user to login first and expect the user will bring the sessionid in their request header cookie then. What's wrong now login/ response header shows: This attempt to set a cookie via a Set-Cookie header was blocked because it had the "Secure" attribute but was not received over a secure connection. I'd like to find a way NOT to use https since it's just not quite a big project so I don't want to make too much effort on configuring https environments. Not sure if I set CORS or use sessionid feature correctly either. Related environment and codes I have a Django backend server in my local network Django 4.2.7 django-cors-headers 4.3.0 ip: http://192.168.10.200:8000 and my frontend dev environment (vue2.x) is on my own laptop ip: http://192.168.10.101:8888 my setting.py is like below # settings.py INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "corsheaders", ] MIDDLEWARE = [ "corsheaders.middleware.CorsMiddleware", "django.middleware.security.SecurityMiddleware", "django.contrib.sessions.middleware.SessionMiddleware", "django.middleware.common.CommonMiddleware", "django.middleware.csrf.CsrfViewMiddleware", "django.contrib.auth.middleware.AuthenticationMiddleware", "django.contrib.messages.middleware.MessageMiddleware", "django.middleware.clickjacking.XFrameOptionsMiddleware", ] CORS_ALLOW_CREDENTIALS = True CORS_ORIGIN_ALLOW_ALL = True SESSION_COOKIE_SAMESITE = "None" SESSION_COOKIE_SECURE = False SECURE_SSL_REDIRECT = False SESSION_COOKIE_HTTPONLY = True CORS_ALLOWED_ORIGINS = ["http://localhost", "http://127.0.0.1", "http://192.168.10.101"] views.py this … -
Challenges with Celery: Managing Long-Running Tasks and Communication Loss in Solo Mode
Good day to all. I've encountered an intriguing issue. I've developed a microservice using Celery that communicates with the main application through REDIS, where the main application also uses Celery. The problem is that I had to run the microservice worker in solo mode because certain functionalities don't operate properly in the regular mode (it's quite complex to explain what and why). Due to the solo mode and the extended task execution time, there is a loss of communication between the workers, causing tasks to re-enter the queue. This occurs because Celery assumes something has gone wrong when the worker doesn't respond for an extended period (tasks take up to 5 hours to complete). Increasing the task execution waiting time isn't feasible, as tasks re-enter the queue due to connection disruption. To avoid tasks re-entering the queue, the heartbeat was disabled. Despite my efforts, tasks still repetitively re-enter the queue even if the process is ongoing My Settings: app.conf.broker_connection_timeout = 10 app.conf.broker_connection_retry = 10 app.conf.result_extended = True app.conf.task_acks_late = True app.conf.task_track_started = True app.conf.task_publish_retry = False app.conf.broker_transport_options = {"visibility_timeout": 86400} app.conf.worker_max_memory_per_child = 10000 app.autodiscover_tasks() The following solutions to the problem were tried, but they did not help Running the microservice … -
