How to combine multiple external REST API services in the same network using Django
I have a central Django REST API and want to serve multiple different machine learning models which I package as individual Flask REST apps. In order to provide a unified REST interface I would like to use the Django REST server as relay / proxy to the individual Flask services. All services are currently built and deployed using docker swarm/compose. What I currently can do is build for each individual Flask app the URL outlets in urls.py and then write code for each GET/POST method in Django to call the Flask outlet. However, I was wondering if in Django I could simply redirect all REST calls requesting: http://localhost/api/v1/model1 To the Flask app providing model1 and the Flask app then response for example to a request of http://localhost/api/v1/model1/submitData without needing Django to explicitly define http://localhost/api/v1/model1/submitData in urls.py. Alternatively I was thinking using Nginx to redirect all calls to http://localhost/api/v1/model1 to the Flask app instead of Django which is the default for http://localhost in my case. I hope the question is clear enough. Bottom line is that I am looking for the most convenient way to have a single REST interface but some REST services should run on individual docker images as … -

Django QuerySet Object Has No Attribute
I'm trying to add a new action to my OrderAdmin class called "order_shipped", whereby it'll send an email to the customer informing them that their order has been shipped. class OrderAdmin(admin.ModelAdmin): actions = ['order_shipped'] def order_shipped(self, request, obj): customer_email = obj.customer.email if request.method == 'POST': send_mail( 'Order Shipped', 'Your order has been shipped.

How to use different tables for authentication in django?
I am from Laravel background and new to django. My concern is how can I use two different tables for authentication in django. For example, admins table for admin authentication and users table for user authentication. Both tables will have column email, password. In laravel, we can use auth guard for this scenario. I want to know how can I implement this in django. I know we can use groups with auth_user table. But I would like to use different tables for user and admin. I have not tried anything yet about this. I am looking for business logic for this implementation in django. Also any code reference will be great help to me. -

How can i create a Root User in Django?

Celery connection to Redis throwing "timed out" error only when delay method called from Django view
I am perplexed with this error and looking for some expert help. Here are the details - I am running a Django application with celery to schedule and execute tasks I use Azure Cache for Redis as the celery backend and broker Azure Redis has SSL port enabled and non-SSL port disabled I have configured SSL using URL scheme (rediss://) as well as celery config (broker_use_ssl and redis_backend_use_ssl) My Task is defined in one django app and the view is in another (though they are deployed together) Everything works also fine in my local setup, where I don't use SSL on redis My django server is running with gunicorn inside a docker container Everything works just fine when celery-beat schedules a task and workers pick them up to execute.

Does Django have any text file search features?
I am using Django Web Framework to store PDF files in FileFields, that will then be converted to .txt files to be used later. Does Django have any features to parse files for queries? My first thought if they diddn't was to use a simple Inverted Index, but I wanted to utilize Django tools as much as I can. I've done several searches in the Django documentation but haven't found anything. I know that the chance of Django having a feature like this was quite low. -

Django Model use a seperate model within model as if it is a past of it
I'm trying to accomplish the following; I have a model customer and model vendor (and others). I would like to have the fields of the model Location available within the customer and vendor models. What I can think of is to create the field similar available in the customer and vendor model, and have a seperate save function on each. What is the best approach? I can think of using the save function, and adding additional code to additionally create a Location entry and using that entry to update the location foreign key, meaning I need to have the field available in both Models.

CS50w Mail project won't print a simple console.log command to the console [closed]
Im currently working my way through the CS50w course working on project nr 3 "Mail" Designing a front-end for an email client that makes API calls to send and receive emails. The program is pre-written, the assignment is to only work with the JS and HTML. My issue is that I can't seem to send a POST request, or anything else for that matter. First I tried to solve the problem on my own, but could not get the "POST" request to get through. Looking at the Network tab in the console view I could only see the GET request loading the from prewritten code. I then followed a tutorial where they got it working. I followed it to the letter without changing anything and can't get a simple print statement to work. I tried deleting and restarting the program without changing anything but without success. Not even a simple print statement after the DOMContentLoaded would print. I don't get any error messages or logs to indicate what seems to be the problem. It just wont print anything on the console. Any help would be greatly appreciated! This is the tutorial I was following, solution starts from 05:14. https://www.youtube.com/watch?v=mj6q0gHOddY&t=438s I've … -

validated_data returns empty dictionary on update
I am building a backend system like Udemy, in this Cart API I am trying to update a cartitem object (a student want to add another course instead of this one) so I want to change the course in the cartitem and change the total_price of the cart. What happens is that when I update the course field it returns HTTP_200_OK response status but the body of the response is the JSON object of the exact same object before updating and the object is not updated models.py class Cart(models.Model): id = models.UUIDField(primary_key=True, default=uuid4) student = models.OneToOneField( User, on_delete=models.CASCADE, related_name='cart') total_price = models.IntegerField(default=0) class CartItem(models.Model): cart = models.ForeignKey( Cart, on_delete=models.CASCADE, related_name='items') course = models.ForeignKey(Course, on_delete=models.CASCADE) views.py class CartItemViewSet(ModelViewSet): http_method_names = ['get', 'post', 'put', 'delete'] def get_queryset(self): return CartItem.objects.filter(cart_id=self.kwargs['cart_pk']) def get_serializer_class(self): if self.request.method == 'PUT': return UpdateCartItemSerializer elif self.request.method == 'POST': return CreateCartItemSerializer else: return CartItemSerializer def get_serializer_context(self): return { 'cart_id': self.kwargs['cart_pk'] } serializers.py class CartItemSerializer(serializers.ModelSerializer): id = serializers.IntegerField(read_only=True) student_id = serializers.SerializerMethodField(read_only=True) def get_student_id(self, cart_item): return Cart.objects.filter(id=self.context['cart_id'])[0].student_id class Meta: model = CartItem fields = ['id', 'student_id', 'course_id'] class CreateCartItemSerializer(serializers.ModelSerializer): id = serializers.IntegerField(read_only=True) def create(self, validated_data): instance = CartItem.objects.get(cart_id=validated_data['cart_id'], course_id=validated_data['course_id']) try: return instance except CartItem.DoesNotExist: instance = CartItem.objects.create(**validated_data) instance.save() return instance class Meta: …
