Question

我正在尝试以以下格式从服务器接收帖子：

{
    "event_type": "test",
    "event_info": {
        "key": "value",
        "more unknown key":"Value pairs"...
    }
}

然后将其序列化为sqlite db。

我找不到一个很好的方法来做到这一点。它不喜欢{}我得到返回“不是有效的字符串。”我还没有找到一个接受json对象的好方法。我可以将json存储为字符串，但我无法弄清楚如何将它转换为字符串。

我有views.py：

from django.shortcuts import render
from .models import Subscription
from .Serializers import SubscriptionSerializer
from rest_framework import viewsets
from django.http import HttpResponse

class SubscriptionViewSet(viewsets.ModelViewSet):
    queryset = Subscription.objects.all().order_by('-date_created')
    serializer_class = SubscriptionSerializer
    http_method_names = ['get', 'post', 'delete']

models.py

from __future__ import unicode_literals

from django.db import models

class Subscription(models.Model):
    event_type = models.TextField(default='Failed to set')
    event_info = models.TextField(default='Failed to set')
    date_created = models.DateTimeField(auto_now=True)

Serializers.py

from rest_framework import serializers
from .models import Subscription

class SubscriptionSerializer(serializers.ModelSerializer):
    class Meta:
        model = Subscription
        fields = ('id', 'event_type', 'event_info')

尝试使用嵌套的序列化程序：

class KeySerializer(serializers.Serializer):
    key = serializers.CharField(max_length=30)


class EventSerializer(serializers.Serializer):
    event_type = serializers.CharField(max_length=30)
    event_info = KeySerializer()

EventSerializer应该能够解析/验证您发布的json。

如何从发布请求中接受Json对象？
