Question

我有一个非常愚蠢的问题。所有主键（id）以字符串形式返回，但我需要整数。

型号：

Django==2.1.5
djangorestframework==3.9.1
djangorestframework-jsonapi==2.7.0

查看：

class Room(models.Model):
    id = models.IntegerField(primary_key=True)
    creator = models.ForeignKey(
        User,
        verbose_name='Creator',
        on_delete=models.CASCADE
    )
    invited = models.ManyToManyField(
        User,
        verbose_name='Invited',
        related_name='invited_user'
    )
    number_1 = models.IntegerField(
        default=1
    )
    number_2 = models.IntegerField(
        default=2
    )
    number_3 = models.IntegerField(
        default=3
    )
    date = models.DateTimeField('Created at', auto_now_add=True)

    class Meta:
        verbose_name = 'Chat room'
        verbose_name_plural = "Chat rooms"
        db_table = 'room'

序列化器：

class Rooms(APIView):
    permission_classes = [permissions.IsAuthenticated]

    @staticmethod
    def get(request):
        # rooms = Room.objects.filter(creator=request.user)
        rooms = Room.objects.all()
        serializer = RoomSerializer(rooms, many=True)
        return Response(serializer.data)

请求：

class RoomSerializer(serializers.ModelSerializer):
    # id = serializers.IntegerField()
    creator = UserSerializer(read_only=True)
    invited = UserSerializer(many=True, read_only=True)

    class Meta:
        id = serializers.IntegerField(label='ID', read_only=True)
        model = Room
        fields = ['id', 'number_1', 'number_2', 'number_3', 'creator', 'invited', 'date']

在请求室ID和用户ID是字符串，但是我需要整数类型。如果另一个字段的类型为整数（数字_1，数字_2，数字_3），则将其返回为整数。我不知道如何解决。感谢您的帮助

谢谢大家的帮助，问题出在设置上。起初，我只是复制它们，然后渗透并删除多余的部分。现在他们看起来像这样

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 1,
    # 'DEFAULT_PERMISSION_CLASSES': (
    #     'rest_framework.permissions.IsAdminUser',
    #     'rest_framework.permissions.AllowAny',
    # ),
    # 'DEFAULT_AUTHENTICATION_CLASSES': (
    #     # 'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    #     'rest_framework.authentication.TokenAuthentication',
    #     'rest_framework.authentication.BasicAuthentication',
    #     'rest_framework.authentication.SessionAuthentication',
    # ),
    # 'EXCEPTION_HANDLER': 'rest_framework_json_api.exceptions.exception_handler',
    # 'DEFAULT_PARSER_CLASSES': (
    #     'rest_framework_json_api.parsers.JSONParser',
    #     'rest_framework.parsers.FormParser',
    #     'rest_framework.parsers.MultiPartParser'
    # ),
    # 'DEFAULT_RENDERER_CLASSES': (
    #     'rest_framework_json_api.renderers.JSONRenderer',
    #     'rest_framework.renderers.BrowsableAPIRenderer',
    # ),
    # 'DEFAULT_METADATA_CLASS': 'rest_framework_json_api.metadata.JSONAPIMetadata',
}

Django rest框架，主键是字符串，而不是整数
