Django Rest Framework Multiple Model Serializtion
I am using Django Rest Framework to make and API. I have and endpoint that i want to use to generate a JSON object that contains data from different models. The viewset for the model is: class InvoiceView(viewsets.ModelViewSet): def list(self, request): cart_id = request.data["cart_id"] shop = Shop.objects.get(id=request.user.id) cart = ShoppingSession.objects.get(id=cart_id) cart_items = CartItem.objects.filter(session=cart_id) paymentmethod = PaymentMethod.objects.get(id=cart.payment_method.id) Invoice = namedtuple('Receipt',('shopname','cart', 'cartitems', 'paymentmethod')) invoice = Invoice( shopname = shop, cart = cart, cartitems = cart_items, paymentmethod = paymentmethod ) serializer = ReceiptSerializer(Invoice) return Response(serializer.data,) The serializers used are: class ShopSerializer(serializers.ModelSerializer): class Meta: model = Shop exclude = ['is_staff', 'is_active', 'start_date'] class ReceiptSerializer(serializers.Serializer): shopname = ShopSerializer() cart = ShoppingSessionSerializer() cartitems = CartItemSerializer(many=True) paymentmethod = PaymentMethodSerializer() When the url is run and a GET request is executed. An error is generated that looks like this. AttributeError: Got AttributeError when attempting to get a value for field `first_name` on serializer `ShopSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `_tuplegetter` instance. Original exception text was: '_collections._tuplegetter' object has no attribute 'first_name'. How are you supposed to user multiple serializers in one serializer class for this kind of custom use-case? -
Django url path matching not working as expected
I have problem with Django model get_absolute_url reverse methods. I have a url pattern that works perfectly but the problem for example when I visit example.com/blog/python/first-post the path works perfectly, but when I try a random path like, example.com/blog/python-randomr9353/first-post it still works correctly even though it shouldn't because, python-randomr9353 is not a valid path and it should return a page not found error.

Grab forms for specific model objects

Password authentication failed for user "postgres" with Django, whereas it works with psql
I've read through the SO posts with the similar error message, but I'm thinking my case is a bit different. I have a kubernetes cluster with a few django pods. If I ssh into one of these pods and type python manage.py runserver, I get following error: django.db.utils.OperationalError: connection to server at "resource-monitor-db-postgresql.resource-monitor-system.svc.cluster.local" (10.152.183.205), port 5432 failed: FATAL: password authentication failed for user "postgres" In settings.py: DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "NAME": "postgres", "USER": "postgres", "PASSWORD": "mypassword123", "HOST": "resource-monitor-db-postgresql.resource-monitor-system.svc.cluster.local", "PORT": "5432", } } The strangest part is that I'm able to log in with psql with the same HOST and PASSWORD. That is, the following command successfully logs in as user postgres. PGPASSWORD="mypassword123" psql --host resource-monitor-db-postgresql.resource-monitor-system.svc.cluster.local -U postgres -d postgres -p 5432 I assume this command is equivalent to the DATABASES property in settings.py. Am I missing something here? Any help would be appreciated. -

How to insert a QR code and some text in a pdf template in Python (preferably) to generate tickets
Hi I am currently making a web application for a congress at my university. The project is not too complicated, but the main functionality is that a user should register himself for the congress and get sent a pass/ticket in PDF through email, with a QR code identifying him/her. This is so that the user can then assist to any event in the congress where a volunteer will read said QR code at the entrance so we can keep track of assistance and reward it at an individual level, as well as keep track of room capacity for COVID reasons. The website is being built using Django and DjangoRest, hence I want to keep using Python wherever I can. I have looked at tools such as ReportLabs python package. It is quite dense and I can't find what I am looking for, which is: Open a pdf template Fill the template with the information regarding the user: name and email for example. Paste/Insert the QR code generated for the user (this is already done). It seems pretty simple but I just can't find how to do it, so any input would be very much appreciated. Maybe I am getting at … -

Django - Transferring data to a new database
I am using Django as my web framework with Django REST API. Time and time again, when I try to migrate the table on production, I get a litany of errors. I believe my migrations on development are out of sync with production, and as a result, chaos. Thus each time I attempt major migrations on production I end up needing to use the nuclear option - delete all migrations, and if that fails, nuke the database. (Are migrations even supposed to be committed?) This time however, I have too much data to lose. I would like to preserve the data. I would like to construct a new database with the new schema, and then manually transfer the old database to the new one. I am not exactly sure how to go about this. Does anyone have any suggestions? Additionally, how can I prevent this from occurring in the future? -

Why Is My Django Post Request Sending Incorrectly Parsed My List of Dictionaries?
Here is my Django view: def sendMail(request): url = 'https://example.com/example' dictwithlist = request.FILES['dictwithlist'] parsed = json.load(dictwithlist) // the log file shows that the lists are intact after json.loads logip(request, json.loads(parsed)) x = requests.post(url, json.loads(clockoutJSON)) return HttpResponse(status=204) If I just send parsed data my express server receives an empty dict, {}. When I log the json.loads(parsed) I find good data, with the lists intact. When the data gets to the other side though, the dictionaries inside the nested list are all removed, replaced by only strings of their keys. I tried using headers as described here: Sending list of dicts as value of dict with requests.post going wrong but I just get 500 errors. I don't know if I'm formatting the headers wrong or not. (because the code has line spacing and I'm copying it) Can anyone help me understand why this is failing? I need that list to get through with its dictionaries intact. -
How to convert svg string to svg file using Python?
Using AJAX I send a svg image to Django using the following function: function uploadSVG(){ var svgImage = document.getElementById("SVG"); var serializer = new XMLSerializer(); var svgStr = serializer.serializeToString(svgImage); $(document).ready(function(){ $.post("ajax_upload_svg/", { csrfmiddlewaretoken: csrftoken, svgImage: svgStr }, function(){ console.log('Done') }); }); } In Django I end up with the svg image as a string using the following function: def uploadSVG(request): svgImg = request.POST.get('svgImage') return HttpResponse('') The string I get looks like this: <svg xmlns="http://www.w3.org/2000/svg" id="SVG" width="460" height="300" style="border:2px solid #000000"><rect x="150" y="70" width="160" height="130" fill="#292b2c"/></svg> How can I convert this svg string into a svg file?
