在Django rest框架中，我可以使用danialfarid / ng-file-

upload上传单个文件

views.py：

class PhotoViewSet(viewsets.ModelViewSet):
    serializer_class = PhotoSerializer
    parser_classes = (MultiPartParser, FormParser,)
    queryset=Photo.objects.all()
    def perform_create(self, serializer):
        serializer.save(blogs=Blogs.objects.latest('created_at'),
                   image=self.request.data.get('image'))

serializers.py：

class PhotoSerializer(serializers.ModelSerializer):
    class Meta:
        model = Photo

models.py：

class Photo(models.Model):
    blogs = models.ForeignKey(Blogs, related_name='blogs_img')
    image = models.ImageField(upload_to=content_file_name)

当我尝试上传多个文件时。我进去

chrome开发人员工具：请求有效负载

------WebKitFormBoundaryjOsYUxPLKB1N69Zn
Content-Disposition: form-data; name="image[0]"; filename="datacable.jpg"
Content-Type: image/jpeg
------WebKitFormBoundaryjOsYUxPLKB1N69Zn
Content-Disposition: form-data; name="image[1]"; filename="datacable2.jpg"
Content-Type: image/jpeg

响应：

{"image":["No file was submitted."]}

我不知道如何编写用于上传多个文件的序列化程序。任何身体都请帮忙。

提前致谢

我设法解决了这个问题，希望对社区有所帮助

serializers.py：

class FileListSerializer ( serializers.Serializer ) :
    image = serializers.ListField(
                       child=serializers.FileField( max_length=100000,
                                         allow_empty_file=False,
                                         use_url=False )
                                )
    def create(self, validated_data):
        blogs=Blogs.objects.latest('created_at')
        image=validated_data.pop('image')
        for img in image:
            photo=Photo.objects.create(image=img,blogs=blogs,**validated_data)
        return photo
class PhotoSerializer(serializers.ModelSerializer):
    class Meta:
        model = Photo
        read_only_fields = ("blogs",)

views.py：

class PhotoViewSet(viewsets.ModelViewSet):
    serializer_class = FileListSerializer
    parser_classes = (MultiPartParser, FormParser,)
    queryset=Photo.objects.all()
