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

That's what the Model.clean() method is for (see docs). Example:

class MyData(models.Model):
    some_json = JSONField()
    ...

    def clean(self):
        if not is_my_schema(self.some_json):
            raise ValidationError('Invalid schema.')
