Django JSONField filtering

Question

I\'m using PostgreSQL and this new field from Django 1.9, JSONField. So I got the following data:

id|data
1 |[{\'animal\': \'cat\', \'name\': \'tom\'}, {\'an         


        

Answer 1

As per the django JSONField docs, it explains that that the data structure matches python native format, with a slightly different approach when querying.

If you know the structure of the JSON, you can also filter on keys as if they were related fields:

object.filter(data__animal='cat')
object.filter(data__name='tom')

By array access:

object.filter(data__0__animal='cat')

Your contains example is almost correct, but your data is in a list and requires:

object.filter(data__contains=[{'animal': 'cat'}])
