JSON to model a class using Django

Question

I'm trying to get a JSON object like:

{
    "username": "clelio",
    "name": "Clelio de Paula",
}

and transform it in:

  class User(models.Model):

     name = models.CharField(max_length=30)
     username = models.CharField(max_length=20)

     def jsonToClass(s):

       aux = json.dumps(s, self)

       self.name = aux['name']
       self.id = aux['id']

So I tried to use the simplejson and one method called jsonToClass():

  >>> import simplejson as json
  >>> u1 = User()
  >>> u1.jsonToClass(face)
  >>> u1.save()

This doesn't work. What is the easiest method to do what I want?

Answer 1

You probably want to look at Django's (de)serialization framework. Given JSON like:

[
  {
    "model": "myapp.user",
    "pk": "89900",
    "fields": {
      "name": "Clelio de Paula"
    }
  }
]

you can save it like this:

from django.core import serializers
for deserialized_object in serializers.deserialize("json", data):
    deserialized_object.save()

Note that I believe you have to use the Django serialization format to use this method, so you might have to adjust your JSON accordingly.

I just realized that

{
    "username": "clelio",
    "name": "Clelio de Paula",
 }

is a dict() object.

So, this is easiest than I thought.

What I need to solve is just

def jsonToClass(self, aux):

    self.name = aux['name']
    self.username = aux['username']

that's it.
