I figured out - we can use pydantic or schema for django. They offers validations also. I preferred pydantic.

<li><a href="https://pydantic-docs.helpmanual.io/" rel="nofollow noreferrer">https://pydantic-docs.helpmanual.io/</a></li>
</ol>
EDIT
Pydentic example
Schema
<pre><code>from typing import List
from pydantic import (
 BaseModel,
 StrictBool,
 StrictInt,
 StrictStr,
)

class Foo(BaseModel):
count: int
size: float = None


class Bar(BaseModel):
 apple = 'x'
 banana = 'y'

class AttributesSchema(BaseModel):
 point: StrictInt
 value: StrictStr
 foo: Foo
 bars: List[Bar]
</code></pre>
will return JSON like
<pre><code>{
 'point': 2,
 'value': 'Any string'
 'foo': {'count': 4, 'size': None},
 'bars': [
 {'apple': 'x1', 'banana': 'y'},
 {'apple': 'x2', 'banana': 'y'},
 ],
}
</code></pre>
Validation -
Add this to your serializer
<pre><code> schema = AttributesSchema
 try:
 errors = schema.validate(data['attributes'])
 except Exception as errors:
 raise serializers.ValidationError(errors)
</code></pre>
Refer pydantic documents, it has everything we need.

Django now natively supports <a href="https://docs.djangoproject.com/en/stable/ref/models/fields/#jsonfield" rel="nofollow noreferrer">JSONField</a>.

I am creating REST API's.
<pre><code>django==3.2.2
djangorestframework==3.12.4
psycopg2==2.8.6
</code></pre>
I am new to Django, python.
I looking for a way to use the JSON field in the Django model.
My model looks like below -
<pre><code>class Question(BaseModel):
.... other code...
 attributes = models.JSONField()
</code></pre>
Now I want the attributes to be a JSON, like below
<pre><code>{
 &quot;index&quot;: 0,
 &quot;guid&quot;: &quot;95161b18-75a8-46bf-bb1f-6d1e16e3d60b&quot;,
 &quot;isActive&quot;: false,
 &quot;latitude&quot;: -25.191983,
 &quot;longitude&quot;: -123.930584,
 &quot;tags&quot;: [
 &quot;esse&quot;,
 &quot;sunt&quot;,
 &quot;quis&quot;
 ],
 &quot;friends&quot;: [
 {
 &quot;id&quot;: 0,
 &quot;name&quot;: &quot;Contreras Weeks&quot;
 },
 {
 &quot;id&quot;: 1,
 &quot;name&quot;: &quot;Dawn Lott&quot;
 }
 ]
}
</code></pre>
Should I create a new model, but creating a new model will make it add to migrations which I do not want.
<ol>
<li>How to create a model for the above?</li>
<li>How can I use the default validation provided by Django ORM on it?</li>
