29147	Postgres JSONField missing to_python	Javier Buzzi	Williams Mendez	"Every other field implements a to_python except for JSONField:

https://github.com/django/django/blob/master/django/contrib/postgres/fields/hstore.py#L38
https://github.com/django/django/blob/master/django/contrib/postgres/fields/array.py#L102
https://github.com/django/django/blob/master/django/contrib/postgres/fields/ranges.py#L47

JSONField defaults to the value, meaning if you pass `'{""object"": ""value""}'` you get back `'{""object"": ""value""}'`. The same example in HStoreField, you pass in `'{""object"": ""value""}'` you get back `{""object"": ""value""}` -- makes the world of difference.
