Django Rest Framework 내에서 업로드 된 파일의 HTTP 요청을 처리하는 방법을 아는 데 어려움이 있습니다. create내 views.py 의 끝점 :
def create(self, request):
file_iobytes = request.FILES["file"].file
self.zipping(file_iobytes)
serializer = FileSerializer(data=request.data) # converts to JSON
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
def zipping(self, file):
# Create a buffer to write the zipfile into
zip_buffer = io.BytesIO()
# Create the zipfile, giving the buffer as the target
with zipfile.ZipFile(zip_buffer, 'w') as zip_file:
#file.seek(0)
zip_file.write(file)
file.close()
models.py
class File(models.Model):
file = models.FileField(upload_to='Myfiles/')
...
def __str__(self):
return self.file.name
serializers.py
class FileSerializer(serializers.ModelSerializer):
class Meta:
model = File
fields = '__all__'
read_only_fields = ('timestamp',)
내 의도는 :
요청을 사용하여 zip 파일을 생성하려면 어떻게해야합니까 (올바른 접근 방식입니까)?
설명이 자명하기를 바랍니다. :)
