我正在使用 S3Boto3Storage 在我的 aws s3 中保存文档并尝试使用简单的缩略图来生成缩略图，请在下面找到代码

模型类

class ThumbnailTestModel(models.Model):
    sample1 = models.FileField(
        storage=S3Boto3Storage(),
        help_text="Field to store the sample document of Professional",
        null=True,
        blank=True,
        upload_to=s3_professional_sample_storage_path)
    sample1_file_name = models.CharField(blank=True,null=True,max_length=1000, default=True)

查看班级

class ThumbnailTestModelView(mixins.CreateModelMixin, mixins.ListModelMixin,
            mixins.UpdateModelMixin, viewsets.GenericViewSet):
queryset = ThumbnailTestModel.objects.all()
permission_classes = (AllowAny, )
serializer_class = ThumbnailSerializer

和序列化

class ThumbnailSerializer(serializers.ModelSerializer):
sample1 = serializers.FileField(read_only=True, required=False, allow_null=True)
sample1_base64 = serializers.CharField(write_only=True, required=False, allow_null=True)
sample1_thumbnail = serializers.SerializerMethodField(required=False, read_only=True, allow_null=True)

class Meta:
    model = ThumbnailTestModel
    fields = ['id','sample1', 'sample1_file_name', 'sample1_base64', 'sample1_thumbnail']

def validate(self, validated_data):
    validated_data = super(ProductProfessionalSerializer,
                           self).validate(validated_data) …
