Django - GenericForeignKey with BaseDatatableView
I'm having trouble using a generic foreign key in BaseDatatableView. Hello. I decided to use a generic foreign key in django. In orm I can do what I need, I can go through content_object to the instance that is connected to this field and easily read the field values of this instance. The problem occurs when I create tables using BaseDatatableView. [models.py] class Warehouse(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') quantity = models.IntegerField() def __str__(self): return f'{self.content_object.name} - {self.quantity}' class Meta: indexes = [ models.Index(fields=['content_type', 'object_id']) ] class Product1(models.Model): name = models.CharField(max_length=50) tag = models.SlugField() note = models.CharField(max_length=20) def __str__(self): return self.tag class Product2(models.Model): name = models.CharField(max_length=50) tag = models.SlugField() note = models.CharField(max_length=20) def __str__(self): return self.tag ( The model architecture is exemplary and only tests relationships ) [table.py] class Product1WarehouseDataTable(BaseDatatableView): model = Warehouse columns = ['content_object__name', 'content_object__tag', 'content_object__note', 'quantity'] def get_initial_queryset(self): ct = ContentType.objects.get_for_model(Product1) qs = self.model.objects.filter(content_type=ct) return qs BaseDatatableView throws an error: Field 'content_object' does not generate an automatic reverse relation and therefore cannot be used for reverse querying. If it is a GenericForeignKey, consider adding a GenericRelation. I want to display data from Product 1 in the table from the Warehouse model. … -
Django CORS configuration not working despite middleware setup
I'm encountering an issue with CORS (Cross-Origin Resource Sharing) configuration in my Django project. Despite configuring CORS settings in my settings.py and adding the CorsMiddleware to the MIDDLEWARE list, I still encounter CORS-related errors when making requests from my frontend application. Here's a summary of my configuration: settings.py (CORS and CSRF settings): # CORS CORS_URLS_REGEX = r"^/api/.*$" CORS_ALLOW_CREDENTIALS = True CORS_ORIGIN_WHITELIST = config("CORS_ORIGIN_WHITELIST", cast=Csv(), default=["http://localhost:3000"]) CORS_ALLOWED_ORIGINS = config("CORS_ALLOWED_ORIGINS", cast=Csv(), default=["localhost:3000"]) CORS_ALLOW_ALL_ORIGINS = config("CORS_ALLOW_ALL_ORIGINS", default=True, cast=bool) CORS_ALLOW_METHODS = ( "DELETE", "GET", "OPTIONS", "PATCH", "POST", "PUT", ) CORS_ALLOW_HEADERS = list(default_headers) + ["Set-Cookie"] # CSRF CSRF_TRUSTED_ORIGINS = config("CSRF_TRUSTED_ORIGINS", cast=Csv()) CSRF_USE_SESSIONS = False SESSION_COOKIE_SECURE = False CSRF_COOKIE_SECURE = False CSRF_COOKIE_SAMESITE = None SESSION_COOKIE_SAMESITE = None settings.py (MIDDLEWARE): MIDDLEWARE = ( "django.middleware.security.SecurityMiddleware", "corsheaders.middleware.CorsMiddleware", "whitenoise.middleware.WhiteNoiseMiddleware", "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", ) Despite having these settings in place, when I attempt to make a request from my frontend application (https://example.com) to my Django backend (https://api.example.com/api/v1/), I receive the following error: Access to XMLHttpRequest at 'https://api.example.com/api/v1/' from origin 'https://example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Django How to save image on my custom path when triggering signals
When I trigger this signal, the image is copied from my ImageModel and uploaded to my OrderItem model in the order_image_file field. The product image is being saved to its original ImageModel destination even though I have defined a custom path in my OrderItem model. def orderImage_upload_path(instance, filename): return f'order_image/{generate_sku()}_{filename}' class OrderItem(models.Model): product_image = models.ForeignKey(ProductImage, on_delete=models.SET_NULL,blank=True,null=True) order_image_file = models.ImageField(blank=True,null=True,upload_to=orderImage_upload_path) my signals @receiver(post_save, sender=OrderItem) def OrderItem_Signals(sender,created ,instance, **kwargs): if created: if not instance.order_image_file and instance.product_image: instance.order_image_file = instance.product_image.image instance.save() -
Passing instances to both model forms, one's model object is updated but about the next, a new object is made
I want to edit both a Drug object and a Bgt object; so I have used Django model forms and have passed instances of both models to it in view. It updates the Bgt object, but Drug object is not updated; instead a new Drug object is made, why? the relationship among both models: Bgt model has a drug field which is a foreignKey field to Drug In this image, 'kostery' was the previous bgt object, which is now changed to 'kostery3' But in the second image, Drug 'Kostery' still exists and a new Drug is created 'Kostery3' View function: The following image is view function: the following is bgt Edit form: this is the drug edit form: this is drug model: -
Django how to use post_save for upload image from another model
I am trying to copy image from my ProductImage models and upload it to my OrderItem models when any new order items will be crate but got this error AttributeError: 'NoneType' object has no attribute 'image' but you can see my ProductImage model have image fields. here my two models: #ProductImage Model class ProductImage(models.Model): product = models.ForeignKey(Product,on_delete=models.CASCADE,blank=True,null=True) image = models.ImageField(upload_to=dynamic_upload_path) thumb_image = models.ImageField(upload_to=dynamic_upload_path,blank=True,null=True) #OrderItem models class OrderItem(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE,blank=True,null=True) product = models.ForeignKey(Product, on_delete=models.SET_NULL,blank=True,null=True) product_image = models.ForeignKey(ProductImage, on_delete=models.SET_NULL,blank=True,null=True) order_image_file = models.ImageField(blank=True,null=True,upload_to=orderImage_upload_path) my signals: @receiver(post_save, sender=OrderItem) def OrderItemSignals(sender, instance, created,**kwargs): if created: instance.order_image_file = instance.product_image.image so basically when any order item will be crate I want to fire my post save for copy image from my product image models and upload it to my order item models image fields. -
The Like button does not change to Dislike, Django
When a user puts a Like, the reverse Dislike button should be displayed, but this does not happen. If you remove the if condition, then like and dislike work separately, the data is written to the database and deleted accordingly. But there is a problem with the if condition. When the user has already put a Like, the information is not taken from the database that they need to put a Dislike instead of a Like. Do not understand why. models.py: class PostLike(models.Model): userlikepost = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) likepost = models.ForeignKey(Userpublication, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) class Meta: unique_together = ('userlikepost', 'likepost') views.py: def show_post(request, post_slug): post = get_object_or_404(Userpublication, slug=post_slug) like_count = PostLike.objects.filter(likepost=post).count() liked_by_current_user = False if request.user.is_authenticated: liked_by_current_user = PostLike.objects.filter(likepost=post, userlikepost=request.user).exists() print(f'liked_by_current_user: {liked_by_current_user}') context = { 'post': post, 'like_count': like_count, 'liked_by_current_user': liked_by_current_user, } return render(request, 'pie/home.html', context) @login_required def like_post(request, post_id): try: post = Userpublication.objects.get(pk=post_id) like, created = PostLike.objects.get_or_create(userlikepost=request.user, likepost=post) like_count = PostLike.objects.filter(likepost=post).count() like_count = PostLike.objects.filter(likepost=post).aggregate(count=Count('id'))['count'] return JsonResponse({'liked': created, 'like_count': like_count}) except Exception as e: return JsonResponse({'error': str(e)}, status=500) @login_required def unlike_post(request, post_id): try: post = Userpublication.objects.get(pk=post_id) like = PostLike.objects.filter(userlikepost=request.user, likepost=post).first() if like: like.delete() like_count = PostLike.objects.filter(likepost=post).count() return JsonResponse({'unliked': True, 'like_count': like_count}) except Exception as e: return JsonResponse({'error': str(e)}, status=500) html: … -

How to integrate real-time computer vision code to django
I have this code for real-time action detection using MediaPipe and a deep learning model. I want to create a Django video streaming web app and integrate this code to detect actions from the frames. I have tried putting the entire code in a class (along with the function definitions of each function called in the code) in a separate python script (camera.py). I then imported the entire class into my views.py but the frames don't show when I run the server. This is the code I would like to integrate into the Django app: sequence = [] sentence = [] predictions = [] threshold = 0.5 cap = cv2.VideoCapture(0) # Set mediapipe model with mp_holistic.Holistic(min_detection_confidence=0.5, min_tracking_confidence=0.5) as holistic: while cap.isOpened(): # Read feed ret, frame = cap.read() # Make detections image, results = mediapipe_detection(frame, holistic) print(results) # Draw landmarks draw_styled_landmarks(image, results) # 2.

How to properly send response to React Frontend from Django Channels?
I am trying to use Django Channels to implement long-polling for a React frontend web app and Django REST backend. I believe that much of what I have is working to some degree, but some thing(s) must be incorrectly configured or coded to produce unexpected results. In short, the problem that I am receiving is that when the Django Channels Consumer sends back a response, it does not immediately go back to the frontend (per console.log(...)s in the code); rather, it seems the Consumer must send another response and then the previous or both responses appear in the frontend. I am trying to implement using AsyncHttpConsumer because Websockets are not possible in our use-case. Asgi.py os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') django_asgi_app = get_asgi_application() application = ProtocolTypeRouter( { "http": URLRouter( longpoll_urlpatterns + [re_path(r"", django_asgi_app)] ), } ) Routing.py longpoll_urlpatterns = [ # Tried using re_path but did not work path("analysisSubscription/<int:analysisId>/", consumers.AnalysisConsumer.as_asgi()), ] Consumers.py class AnalysisConsumer(AsyncHttpConsumer): async def handle(self, body): print("In Handle") print(self.scope) self.analysisId = self.scope["url_route"]["kwargs"]["analysisId"] self.analysis_group_name = f"analysis_{self.analysisId}" # Register with the appropriate channel await self.channel_layer.group_add(self.analysis_group_name, self.channel_name) await self.send_headers(headers=[ (b"Content-type", b"application/json"), (b"Access-Control-Allow-Origin", b"*"), (b"Access-Control-Allow-Headers", b"Origin, X-Requested-With, Content-Type, Accept, Authorization"),]) #The server won't send the headers unless we start sending the body await self.send_body(b"", more_body=True) … -

pandas read_sql using Django.db.connection
Is there a recommended way to utilize pandas read_sql from within a Django app? I was using a much older version of pandas and this worked: import django.db.connection import pandas as pd df = pd.read_sql("select employee.name from employee;", con=connection) Now, I'm getting this error from read_sql: UserWarning: pandas only supports SQLAlchemy connectable (engine/connection) or database string URI or sqlite3 DBAPI2 connection. Other DBAPI2 objects are not tested. Please consider using SQLAlchemy. The query seems to work even with the warning but I don't want to take chances that it might break. I was using the Django.db.connection so that pandas makes use of the db connection pooling within Django. I can successfully use a connection string with the read_sql method but I don't want pandas opening up a bunch of connections in a multi-user system. Same with SQLAlchemy - I don't want to add another connection pool into the app. Any advice or workarounds? I haven't found anything in the pandas or Django documentation covering this.

Is there a way to have SSO using Atlassian for our external Django application?
We created a Forge app and we have an existing Django/Python application. Our forge app app has a connect button and when the user clicks it we want the user to automatically login with the credentials from Jira. Is there a way of possibly doing that? We followed Django-OAuth-Toolkit documentation to build an OAuth 2.0 provider. We managed to get our access token using bash. We followed the documentation on the Atlassian website for External OAuth 2.0 for Forge apps. But we could not get that working. We were expecting some type of response using the Google provider but kept getting errors. We aren't sure exactly what to do after this. The documentation vague. -

transaction.atomic() rolls back if another query is executed
I am having issues with Django's transaction.atomic. I have this app that users can update their information, but I will be giving an example here. So I want to prevent update to this field if more than one requests is received, so I want to lock the row which is why I am using transaction.atomic and select_for_update. So I have a UserProfile model that I want to update some information, the method which i use to update is is below Class Profile(models.Model): def get_queryset(self): return self.__class__.objects.filter(id=self.id) @transaction.atomic() def update_age( self, age: int, ) -> None: obj = self.get_queryset().select_for_update().get() obj.age = age obj.save() Below is the view class UserProfileView(APIView): def put(self, request): profile = rquest.user.profile profile.update_age(request.data["age"]) UpdateHistory.objects.create(user=request.user, updated_field="age") The issue is UpdateHistory object is created but the age update is rolled back, but when I remove the creation of the UpdateHistory, the age is actually updated successfully. So the above code only creates UpdateHistory, but doesnt update the UserProfile's age. But if I remove the line UpdateHistory.objects.create(user=request.user, updated_field="age"), the age is updated successfully. No exception is being raised at all, this has been confusing me for days. Hopefully I can get some help. Thanks in advance -
