django-serializer

问题 I have the following models: class Address(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) .... class Meta: abstract = True class BillingAddress(Address): is_default = models.BooleanField() ... class Meta: db_table = 'billing_address' I'm trying to build a serializer for BillingAddress: class AddressSerializer(serializers.ModelSerializer): class Meta: abstract = True model = AddressModel class BillingAddressSerializer(AddressSerializer

问题 In ASP.NET there is entity framework or something called code first from database. Is there something similar for Django? I usually work with a pre-existing database that I need to create a backend (and subsequently a front end) for. Some of these RDBs have many tables and relations so manually writing models isn't a good idea. I've scoured Google for solutions but have come up relatively empty handed. Thoughts would be appreciated. Thanks! 回答1: You can use the information on this link.

问题 I am trying to serialise a json payload that has a field with an array, the .is_valid() check is returning true but I am getting KeyError: 'passengers' when I try to do this serializer.data['passengers'] but the other fields work fine (such as booking_number and status). This is the response.data I am passing to the seralizer: {'booking_number': 2839, 'passengers': [{'first_name': 'Jack', 'surname': 'Smith', 'email': 'smith@mail.com', 'phone_number': '1234'}], 'status': 'ON_HOLD'} My
