Django saving json value to database/model

Question

Im new to django and im trying to save json to database. The problem is that im able to get data the data in my views but not sure how to save it in

Answer 1

Assuming a model of:

class User(models.Model):
  name = models.CharField()
  phone_number = models.CharField()

Sending json of {"name":"Test User", "phone_number":"123-456-7890"}

In the view you could do the following to save it to the database.

def SaveUser(request):
  body_unicode = request.body.decode('utf-8')
  body = json.loads(body_unicode)
  u = User(**body)
  u.save()
  return JsonResponse({"result": "OK"})

Answer 2

If you're using Postgres, you can store json with JSONField (read more), but if not, you need parse json to string and save with CharField/TextField using json.dumps(data). To recovery data, use json string to dict with json.loads(json_string)

Remember to import json lib: import json

Answer 3

according to Django doc you can use :

from django.contrib.postgres.fields import JSONField
from django.db import models

class Dog(models.Model):
    name = models.CharField(max_length=200)
    data = JSONField()

    def __str__(self):
        return self.name

then create with this :

Dog.objects.create(name='Rufus', data={
     'breed': 'labrador',
     'owner': {
         'name': 'Bob',
         'other_pets': [{
             'name': 'Fishy',
         }],
     },
})

If I understand your question clearly then Your view should be something like.

def add_comments(request):
    if 'application/x-www-form-urlencoded' in request.META['CONTENT_TYPE']:
        print 'hi'
        data = json.loads(request.body)
        comment = data.get('comment', None)
        id = data.get('id', None)
        title = data.get('title', None) 

        post = Post.objects.get(id = id)
        com = Comment()
        com. comments = comment
        com.title = post
        com.save()

If you want to store the intact JSON, try using the django-jsonfield project: https://github.com/dmkoch/django-jsonfield
