django JSONField regex

Question

I'm using Django 2.1 and I have model with JSONField(record):

{
    'fields': [
        {'tag': 'x','value': '12345'},
        {'tag': 'y','value': '67890'}
    ]
}

To query exact 'value' I use:

Data.objects.filter(record__fields__contains=[{'tag':'x', 'value': '12345'}])

My question is, how to use regex with 'value'? e.g.

Data.objects.filter(record__fields__contains=[{'tag':'x', 'value': '/^123.*/'}])

Answer 1

you can simple:

Data.objects.filter(record__icontains='{"tag":"x", "value": "123')
