django rest 實現多圖片上傳

1. models 配置

   class ImageItems(models.Model):
   image = models.ImageField(upload_to='static/images/%Y/%m/%d', null=False, blank=False, verbose_name='圖片url')
   
   class Meta:
       verbose_name = '圖片集合'
       verbose_name_plural = verbose_name

   2.serializers 配置

   class ListImgSerializer(serializers.Serializer):
   img = serializers.ListField(
       child=serializers.FileField(max_length=100000,
                                   allow_empty_file=False,
                                   use_url=True), write_only=True
   )
   img_list = serializers.ListField(
       child=serializers.CharField(max_length=1000, ), read_only=True
   )
   code = serializers.IntegerField(read_only=True)
   
   def create(self, validated_data):
       imgs = validated_data.get('img')
       images = []
       for index, url in enumerate(imgs):
           image = ImageItems.objects.create(image=url)
           imageItems = ImageItemsSerializer(image, context=self.context)
           images.append(imageItems.data['image'])
       return {"img_list": images, "code": 201}

2. viewSet 配置

   class ImageItemsViewSet(mixins.CreateModelMixin, viewsets.GenericViewSet):
   queryset = ImageItems.objects.all()
   serializer_class = ListImgSerializer
   parser_classes = (MultiPartParser, FileUploadParser,)
