How to override existing '/api/products/' to return more fields in Django-osacr-api?
Django-oscar-api-override setup I am new to Oscar Api, And I need to added extra fields to the default '/api/products' response. Additional fields to add: description, meta_title, meta_description, rating, attributes from oscar.core.loading import get_class from rest_framework import serializers from oscarapi.serializers import checkout, product from oscarapi.serializers.product import ( ProductImageSerializer, ProductLinkSerializer) class MyProductLinkSerializer(ProductLinkSerializer): images = ProductImageSerializer(many=True, required=False) class Meta(ProductLinkSerializer.Meta): fields = ('url', 'id', 'title', 'images', 'rating', 'meta_title', 'meta_description') I tried the above code from documentation to see if it overrides.

Apply filter to field with lookup
I have seen a couple of similar questions on StackOverflow (Troubleshooting "Related Field has invalid lookup: icontains", Django error Related Field got invalid lookup: icontains, Related Field got invalid lookup: icontains, Django: Unsupported lookup 'case_exact' for CharField or join on the field not permitted, Filtering on Foreign Keys in Django) but unfortunately the answers on those questions have not helped me. If a hotel only has four double rooms and there are already four bookings for the first week of October, I want to prevent the next user being able to make a fifth booking for the first week of October. This was working - RoomBookings.objects.filter(HotelName__icontains=hotel.HotelName, RoomType__icontains= hotel.RoomType, ArrivalDate__lt=RoomBookingsForm['DepartureDate'], DepartureDate__gt=RoomBookingsForm['ArrivalDate']) But then I changed the HotelName field in the RoomBookings model from CharField to ForiegnKey. And now I cannot figure out how to do a reverse lookup. These are my failed attempts - # queryset2 = RoomBookings.objects.filter(HotelName__HotelName__icontains=hotel.HotelName) # queryset2 = RoomBookings.objects.filter(HotelName__Hotel__HotelName__icontains=hotel.HotelName) # queryset2 = RoomBookings.objects.filter(HotelName__Hotel__HotelName_exact=hotel.HotelName) # queryset2 = RoomBookings.objects.filter(HotelName__HotelName_exact=hotel.HotelName) class Hotel(models.Model): HotelName = models.CharField(max_length=60, null=False) HotelOwner = models.CharField(max_length=60, null=True) FirstLineAddress = models.CharField(max_length=60, null=False) SecondLineAddress = models.CharField(max_length=60, null=True) PostCode = models.CharField(max_length=60, null=False) Country = CountryField(max_length=120, null=True) PhoneNumber = PhoneNumberField(null=True, blank=False, unique=True) Email = models.EmailField(max_length=254) def __str__(self): return self.HotelName class RoomType(models.Model): HotelName … -
How to add new field in model after custom migration which access model before new field?
I have custom migration file which creates entry in table user. Initial working project has these migrations: 1. 001_initial.py # creates model with some fields 2. 002_custom_user_data.py # adds data in "user" due some middle requirement after some time.

Please help: Reverse for 'all_clients' with keyword arguments '{'client_id': 3}' not found. 1 pattern(s) tried: ['clients/all_clients/$']

Can I delete the third-party Python library `future` after moving exclusively to Python 3?
The future module (https://pypi.org/project/future/) is "the missing compatibility layer between Python 2 and Python 3." I have a Django project that was ported from Python 2 to 3 long ago, but future is still a requirement. My question is: now that the project only needs to run on Python 3, is there much danger in deleting the requirement for future? My own investigations: After deleting future from requirements.txt, the unit tests still pass. Grepping my project source, I don't see any imports of builtins, which future shadows in Python 2. The future docs say The imports have no effect on Python 3. On Python 2, they shadow the corresponding builtins, which normally have different semantics on Python 3 versus 2, to provide their Python 3 semantics. So deleting future seems pretty safe, but is there anything I'm missing? Thanks. -

Django REST Framework - How to compare two given values?
at my Django API application, I have a serializer that should validate a given pin but I'm always running into: TypeError: string indices must be integers def validate_old_pin(self, value): user = self.context['request'].user if value['old_pin'] != user.pin: # <- Breakpoint raise serializers.ValidationError( ({'old_pin': _("Your old PIN was entered incorrectly. Please try again.")}) ) return value Why do I get this? What is the most effective way to simply check if the two pin field match? Thanks in advance.
