Question

我正在使用Django和restframework-json-api软件包开发REST API。我提出以下要求

const sortedlocations = locations.sort((a, b) => a.distance - b.distance);
this.setState({locations: sortedlocations});

我得到这个答复

curl --location --request POST 'http://localhost:8000/api/students/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "data": {
        "type": "students",
        "attributes": {
            "first_name": "First Name",
            "last_name": "Last Name"
        }
    }
}'

这是我的代码： models.py

{
    "errors": [
        {
            "detail": "This field is required.",
            "status": "400",
            "source": {
                "pointer": "/data/attributes/first_name"
            },
            "code": "required"
        }
    ]
}

serializers.py

class Student(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    email = models.EmailField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

views.py

class StudentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Student
        fields = ('first_name',)

urls.py

class StudentsViewSet(viewsets.ModelViewSet):
    queryset = Student.objects.all()
    parser_classes = (JSONParser, FormParser, MultiPartParser)
    serializer_class = StudentSerializer

settings.py

router = routers.DefaultRouter()
router.register(r'students', views.StudentsViewSet, 'student')


urlpatterns = [
    path('', views.index, name='index'),
    path('api/', include(router.urls))
]

如果我改为不使用JSONParser并使用常规的django请求格式而不是Json API，则可以正常工作。我想念什么？

您使用的解析器与DRF的“解析器”部分中引用的推荐JSONParser不同： https://www.django-rest-framework.org/api-guide/parsers/

REST_FRAMEWORK = {
    'DEFAULT_PARSER_CLASSES': [
        'rest_framework.parsers.JSONParser',
    ]
}
