Access users values in python, django
I'm a bit stuck in figuring out how to access the body, title, author ... values, so that I can show them in the user profile.

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?

Checking properties of an object based on separete view (Django|Django-Rest-Framework)
I am using django-rest-framework and React.js. I need a seperate function in the backend to check if CartItem.amount is lower then ProductStock.quantity, if CartItem.product equals ProductStock.id of course (this part does not work).

Duplicate instance returned in QuerySet

Is there a way to create an entity that stores proposed changes that mirrors the structure of the original entity? -
How to include ManyToMany Fields in DjangoRestFramework?
class EntityServiceSerializer(serializers.ModelSerializer): class Meta: model = Service fields = '__all__' class EntityCreateSerializer(serializers.ModelSerializer): entity_service = EntityServiceSerializerThrough(read_only=True, source='serviceschedule_set', many=True) class Meta: model = Entity fields = '__all__' Model looks like this class Entity(models.Model): entity_service = models.ManyToManyField(Service, through='ServiceSchedule') class ServiceSchedule(models.Model): service = models.ForeignKey(Service, on_delete=models.CASCADE) entity = models.ForeignKey(Entity, on_delete=models.CASCADE) class Service(models.Model): service_name = models.CharField(max_length=256, null=True) slug = models.SlugField(max_length=128, unique=True, null=False, editable=False) created_at = models.DateTimeField(editable=False, default=timezone.now) updated_at = models.DateTimeField(default=timezone.now) animal = models.ForeignKey(Animal, on_delete=models.CASCADE, default=None) I have these serializers (there are more fields in entity model, but they're irrelevant since the only problem i have is with the Many2Many) The thing is, when i put in body "entity_service": [1,2] in the response i still get = []. Even though i have in my database Services with pk 1,2,3,4. Do you know how can i make it work?
