django-rest-framework different fields for serialization -


i have example like

[   {         "url": "/api/post/12/",          "user": "/api/users/1/",          "created": "2013-08-06t04:52:28z",          "updated": "2013-08-06t04:52:28z",          "date": "2013-08-06t04:52:28z",          "show": true,          "title": "test post",          "body": null,          "role": "text",          "image_url": "",          "image": ""     },      {         "url": "/api/post/13/",          "user": "/api/users/1/",          "created": "2013-08-06t04:53:19z",          "updated": "2013-08-06t04:53:19z",          "date": "2013-08-06t04:53:19z",          "show": true,          "title": "test post",          "body": null,          "role": "image",          "image_url": "http://127.0.0.1:8000/media/photos/photo_1.jpg",          "image": "photos/photo_1.jpg"     }  ]

i want hyperlinkedmodelserializer class not show image_url , image if it's text role.

is possible?

you override to_native in serializer subclass strip unwanted fields in case.

something like: 

def to_native(self, obj):     as_native = super(myserializer, self).to_native(obj)      # remove image_url , image fields if text role.     if as_native["role"] == "text":         as_native.pop('image_url', none)         as_native.pop('image', none)      return as_native

i hope helps.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
