serialization - Serializing a lucene query into JSON? -

is there best practice serializing lucene queries json format? saw elastic search query dsl, looks strays lucene terminology. also, lucene appears moving away maintaining serialization code.

i looking have "standard" format in json. need able save query, when users saving queries on web ui, not entering title:matrix. have able search saved searches, edit saved searches. nice if there standard json format representing query. lucene query.

i know little of elasticsearch i'm guessing doing (also) because back upwards query functionality other lucene does.

if need marshall/unmarshall query, treat whole single unescaped string. if want break downwards key-value (field name/value) elements, don't forget can have conjuction/disjunction/etc. not trivial.

as comment on serialization code - don't think applies queries. query has abstract tostring(string field) method each query subclass should implement , provide parseable string. tostring() calls - , hasn't alter long while, nor see changing query not provide other way of getting string representation changing break lot of code.

django - Access session in user model .save() - is possible access current session in user model .save()? pseudo code of want achieve: # users.models.py def save(self, *args, **kwargs): created = true if self.pk: created = false super(abstractuser, self).save(*args, **kwargs) # post-save if created: look_for_invite_in_session_and_register_if_found(self, session) seems wrong in architecture. shouldn't access request in models layer. work request must done in view. can this: user, created = abstractuser.objects.get_or_create(name=name) if created: look_for_invite_in_session_and_register_if_found(user, request.session) django session
