Comment:

 [https://github.com/django/django/pull/7071 PR #7071] looks good to me. I
 left a comment about the type of the `encoding` parameter in the pull
 request.

Comment:

 This [https://github.com/django/django/pull/7071 PR] adds custom encoding
 support.

 The decoding part is another story. The patch currently recommends using
 `from_db`/`from_db_value` hooks. If anyone can come with a concrete
 proposal with another method, please propose it.

Comment (by debanshuk):

 We could use a custom data type representation scheme to represent dates,
 decimals etc in JSON.

 The scheme could be similar to what MongoDB uses for it's extended JSON
 (https://docs.mongodb.com/manual/reference/mongodb-extended-json/#bson-
 data-types-and-associated-representations).
 Eg: a date object would be stored as {{{ {"$date": }
 }}}

 Or,

 It could be something more sophisticated and generic like
 {{{
 {
 "$djExtJson": {
 "$type": ,
 "$args": ,
 "$kwargs": 
 }
 }
 }}}
 Where '$type' would be the full path of a class (eg, {{{ datetime.date }}}
 or {{{ decimal.Decimal }}}) and '$args' and '$kwargs' would be the
 arguments for constructor of the class.

 So a date object would be stored as:
 {{{
 {"$djExtJson": {"$type": "datetime.date", "$args": ["2016", "7", "6"]}}
 }}}

 and a decimal object as:
 {{{
 {"$djExtJson": {"$type": "decimal.Decimal", "$args": ["21.5"]}}
 }}}

 Using this format, one would be able to store any class's object in JSON.
 Eg:
 {{{
 # my_utils.py
 class ABC():
 def __init__(self, dt: date):
 self.date = dt
 }}}
 An object of above class could be stored as:
 {{{
 {"$djExtJson": {
 "$type": "my_utils.ABC",
 "$args": [{"$djExtJson": {"$type": "datetime.date", "$args": ["2016",
 "7", "6"]}}]
 }}
 }}}

 Deserialisation of objects using above format would be very simple, as we
 would have type information stored withing the object with all the
 arguments required to call constructor of that type, so we would be able
 to call the constructor and get the object.

 For serialisation, it won't be possible to get arguments which need to be
 passed to a class's constructor just by looking at a object of that class.
 So for that, we can have custom code in Django for supporting
 serialisation of common standard library objects and builtins. And for
 user defined classes, we can created a mixin (we may call it {{{
 DjExtJsonSerialisable }}}) which would simply stores arguments (and
 keyword arguments) passed to the constructor of a user defined class in
 some attribute, when a object of a class inheriting from at mixin is
 created (attribute can {{{ __dj_ext_json_data__ }}}).

Comment:

 I hit the same problem: https://groups.google.com/d/msg/django-
 developers/upg9pgGvaUs/LMN8Xfq8EQAJ

 If Django doesn't provide an escape hatch, I suspect I won't be the only
 one to resort to monkey-patching.

 Right now I don't have time to dig into this issue but I don't think we
 can leave it there altogether.

Comment:

 [https://github.com/django/django/pull/5928 Doc patch]. I avoided
 recommending a particular third-party field since we avoid that as it's
 difficult to curate a list of packages that doesn't go stale.
