Django Rest Framework - 使用序列化程序发送json请求库

Question

我喜欢DRF设置，它接收json中的数据并将其存储在django中。串行是继

class ReservationSerializer(serializers.ModelSerializer): 
    room = RoomSerializer() 
    reserved_days = DaySerializer(many=True) 
    additional_services = AdditionalServicesSerializer(many=True) 


    class Meta: 
     model = Reservation 
     fields = [ 
      'start', 
      'end', 
      'check_in_time', 
      'check_out_time', 
      'reserved_days', 
      'additional_services', 
      'room', 
      'has_refund', 
      'payed', 
      'guest_name', 
      'reservation_number', 
     ] 

我可以用这个序列化准备在JSON模型，然后用Requests库发送此JSON？

这是可行，如果你看到需要。尽管JSON编码是在完整的HTTPResponse子类的Response对象中完成的，因此您需要编码自己的数据：

import json 
import requests 

my_objects = Reservation.objects.all() 
serializer = ReservationSerializer(data=my_objects, many=True) 
if serializer.is_valid(): 
    # now you do your encoding: 
    encoded_data = json.dumps(serializer.data) 
    response = requests.post(your_url, 
          headers={'Content-Type': 'application/json'}, 
          data=encoded_data)
