Question

“”“我正在使用DRF创建API（注释）。现在我很困惑，我需要获得一个专辑以便可以完全创建我的api，但是到目前为止，除专辑之外的所有其他字段都出现了。专辑= serializers.CharField（来源='comments.name_album'，read_only = True）没有帮助。这就是我在答案中得到的全部答案{“ album”：“”，“ post”：“ ahsdh”，“ author”：“ philip”，“ text”：“ ahsdhah”}“”“

class AlbumCreateSerializer(serializers.ModelSerializer):
    album = serializers.CharField(source='comments.name_album', read_only=True)
    class Meta:
        model = Comments
        fields = [
                    'album',
                    'post',
                    'author',
                    'text',
                  ]

#apiview
class AlbumCreateAPIView(CreateAPIView):
    queryset = Comments.objects.all()
    serializer_class = AlbumCreateSerializer
    permission_classes = [IsAuthenticated, IsAdminUser]

    def post(self, request,pk=None, *args, **kwargs):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            ready_data = serializer.save()
            return Response(ready_data.data, status=status.HTTP_201_CREATED)
        return Response(serializer.data, status=status.HTTP_400_BAD_REQUEST)

class Comments(models.Model):
    album = models.ForeignKey(Album, on_delete=models.CASCADE, related_name='comments')
    post = models.CharField(max_length=100)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    text = models.TextField(max_length=500)
    publish_date = models.DateTimeField(default=timezone.now())

    def __str__(self):
        return self.text

您的创建序列化程序应定义一个create方法，而不要发布。

示例https://www.django-rest-framework.org/api-guide/serializers/#saving-instances

class AlbumCreateAPIView(CreateAPIView):
    queryset = Comments.objects.all()
    serializer_class = AlbumCreateSerializer
    permission_classes = [IsAuthenticated, IsAdminUser]

    def create(self, request,pk=None, *args, **kwargs):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            ready_data = serializer.save()
            return Response(ready_data.data, status=status.HTTP_201_CREATED)
        return Response(serializer.data, status=status.HTTP_400_BAD_REQUEST)

从类型为Foreignkey的字段中选择值
