PdfFileReader.getFields() returns {} | django
I'm trying to read a pdf form with django. The point is that in another view of my views.py I've succeed into do it by using PyPDF2 and its PdfFileReader.getFields() method. Now the problem is that the reading is not working properly: I've checked with adobe acrobat and the file still is a form with actually fields, so I don't really have any idea of what could be the problem. I'm attaching here the relevant portion of the code: if request.method == "POST": form = Form(request.POST, request.FILES) # the form refer to a model called 'New Request' if form.is_valid(): form.save() File = request.FILES['File'].name full_filename = os.path.join(BASE_DIR, 'media/media', File) f = PdfFileReader(full_filename) fields = f.getFields() fdfinfo = dict((k, v.get('/V', '')) for k, v in fields.items()) k = creare_from_pdf2(request, fdfinfo, pk) # this is a custom function nr = NewRequest.objects.all() #I'm deleting the object uploaded because it won't be useful anymore nr.delete() os.remove(full_filename) If I display print(fdfinfo) it actually shows {}. This of course is leading to error when fdfinfo passes into the 'create_from_pdf_2' function. I don't really know what the problem could be, also because in another view I made exactly the same and it works: if request.method=='POST': form = Form(request.POST, … -
How to sort and count values when they are selected?
I send a request to the site https://swapi.dev/ the received data needs to be sorted: Provide the functionality to count the occurrences of values (combination of values) for columns. For example when selecting the columns date and homeworld the table should show the counts as follows: my code is not very good because I write something like this for the first time: import requests from rest_framework.views import APIView from rest_framework.viewsets import ModelViewSet from rest_framework import status from rest_framework.response import Response from datetime import datetime from rest_framework import filters from rest_framework.pagination import PageNumberPagination from rest_framework.decorators import action # class StarWarsAPIListPagination(PageNumberPagination): # page_size = 4 # page_size_query_param = 'page_size' # max_page_size = 20 class StarView(APIView): # pagination_class = StarWarsAPIListPagination # filter_backends = (filters.OrderingFilter) # ordering_fields = ('name',) def get(self, request): date = datetime.today() page = request.query_params.get('page', 1) url = f'https://swapi.dev/api/people/?page={page}' response = requests.get(url, date).json() return Response(response, status=status.HTTP_200_OK) class StartDateView(APIView): def get(self, request): date = datetime.today() page = request.query_params.get('page', 1) url = f'https://swapi.dev/api/people/?page={page}' response = requests.get(url).json() a = response['results'][0]['name'] # a = response['results'] # for i in range(len(a)): # if a[i]["name"] == "R2-D2": # return Response(a[i]['name'], status=status.HTTP_200_OK) -

Djnago model instance only update after calling objects.get() again (DRF Test case)
I have an APIView (DRF), where I set the user is_active field to False instead of deleting him, everything works as expected, but I have a wired behavior when I try to make a test case for the view, I try to test if the field 'is_active' is False after calling the ApiView but it remains 'True' if change the code a little bit and call user.objects.get() with the same user email after calling the ApiView, the new instance field is_active is False.

Security Scanning of files other than source code
I have some files that I need to download and then upload to a specific location during execution of code. These files are other than source code files but required by the source code(.yaml, .xml, some .zip folders etc.) I need to scan these files for any security vulnerabilities.

Advanced Python Scheduler running multiple times in production (Django on DigitalOcean)
I have a simple use of Advanced Python Scheduler to run some django code overnight everyday. The code itself works fine, and locally using manage.py runserver with the --noreload flag everything is spot on. My problem is in production where the APS code is being executed three times; as an example, I receive a status update by email at the end of the process each night, and this email is delivered 3 times within a 10 second period. Where should I be looking to replicate the protections of the --noreload flag in a production set up? -
How to apply different permission classes for different http requests
I have a UserViewSetthat supports get, post, patch, and delete HTTP requests. I have admins with different roles, some of them can delete users, and others cannot.

I tried to do something like this: class UserViewSet(ModelViewSet): queryset = User.objects.all() http_method_names = ['get', 'post', 'patch', 'delete'] def get_serializer_class(self): if self.request.method == 'PATCH': self.permission_classes = [CanEdit] return UpdateUserSerializer elif self.request.method == 'DELETE': self.permission_classes = [CanDelete] return UserSerializer I am not sure if this is the best practice to do this. -

Overriding is_valid in Nested serializer to be able to process child model with same information during update()
I'm trying to make my nested serializer to be able to process updating when I'm only updating for the parent model. The default action in drf is that the serializer cant tell if ur child model is trying to updating or create, there's a solution where you just turn off the validation, which I don't think is ideal for the database and iots implication. I've scour about this topic for like 2 days and I think the ideal approach to this is to override the is_valid method to be able to just return the object. Idea from : Django REST Framework ModelSerializer get_or_create functionality from django.core.exceptions import ObjectDoesNotExist, MultipleObjectsReturned class MyModelSerializer(serializers.ModelSerializer): def is_valid(self, raise_exception=False): if hasattr(self, 'initial_data'): # If we are instantiating with data={something} try: # Try to get the object in question obj = Security.objects.get(**self.initial_data) except (ObjectDoesNotExist, MultipleObjectsReturned): # Except not finding the object or the data being ambiguous # for defining it. Then validate the data as usual return super().is_valid(raise_exception) else: # If the object is found add it to the serializer. Then # validate the data as usual self.instance = obj return super().is_valid(raise_exception) else: # If the Serializer was instantiated with just an object, and no # … -
