我想django-rest-framwork在保存之前编辑序列化程序对象.这就是我目前的做法 -

def upload(request):
    if request.method == 'POST':
        form = ImageForm(request.POST, request.FILES)
        if form.is_valid(): # All validation rules pass
             obj = form.save(commit=False)
             obj.user_id = 15
             obj.save()

如何使用django-rest-framework序列化程序对象执行此操作？

@api_view(['POST','GET'])
def upload_serializers(request):
    if request.method == 'POST':
         serializer = FilesSerializer(data=request.DATA, files=request.FILES)
         if serializer.is_valid():
              serializer.save()

是否可以通过psycopg2运行以下命令？如果是这样,我该怎么办？

COPY table_name(col1,col2) FROM 'path/to/file.csv' WITH HEADER DELIMITER ',' CSV;
