django postgresql json field schema validation

Question

I have a django model with a JSONField (django.contrib.postgres.fields.JSONField) Is there any way that I can validate model data against a json schema file?

Answer 1

you could use cerberus to validate your data against a schema

from cerberus import Validator

schema = {'name': {'type': 'string'}}
v = Validator(schema)
data = {'name': 'john doe'}
v.validate(data)  # returns "True" (if passed)
v.errors  # this would return the error dict (or on empty dict in case of no errors)

it's pretty straightforward to use (also due to it's good documentation -> validation rules: http://docs.python-cerberus.org/en/stable/validation-rules.html)
