How to store a dictionary in a Django database model's field

Question

I need to save a dictionary in a model\'s field. How do I do that?

For example I have this code:

def create_random_bill(self):
    name_chars = re.co         


        

Answer 1

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

and create with this :

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

I hope this could help you.

If using PostGres you can store it in natively supported JSON field: https://docs.djangoproject.com/en/dev/ref/contrib/postgres/fields/#jsonfield

Otherwise I'd recommend @ramiro answer with 3rd party lib https://stackoverflow.com/a/16437627/803174

I think that I would create the field as models.CharField() and then encode the dictionary as a JSON string and save that string into the database. Then you can decode the JSON string back into a dictionary when you read it out.
