How can I accept Json object from post request? - django

Question

I'm trying to receive a post from a server in the format:
{
"event_type": "test",
"event_info": {
"key": "value",
"more unknown key":"Value pairs"...
}
}
Then serialize it into a sqlite db.
I'm not finding a good way to do this. It doesn't like {} I get returned "Not a valid string." I haven't found a good way to accept the json object. I could just store the json as a string but I can't figure out how to convert it to a string either.
I have 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')

Answer 1

Try using nested serializer:
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 should be able to parse/validate json you posted.
