Result:

Preserving JSON object keys order

By default, Django uses the jsonb internal type for JSONField (for PostgreSQL).

From the Postgres documentation:

<...> jsonb does not preserve white space, does not preserve the order of object keys, and does not keep duplicate object keys. If duplicate keys are specified in the input, only the last value is kept.

In general, most applications should prefer to store JSON data as jsonb, unless there are quite specialized needs, such as legacy assumptions about ordering of object keys.

If you really do need to preserve the key order, use OrderedJSONField. It uses the TEXT type to store data:

from django.db import models
from django.utils.translation import gettext_lazy as _
from paper_jsoneditor.fields import OrderedJSONField


class SampleModel(models.Model):
    data = OrderedJSONField(_("JSON"))

    class Meta:
        verbose_name = _("Sample")
