How can I get pymongo to always return str and not unicode? -


from pymongo docs:

mongodb stores data in bson format. bson strings utf-8 encoded pymongo must ensure strings stores contain valid utf-8 data. regular strings () > validated , stored unaltered. unicode strings () encoded utf-8 first. > reason our example string represented in python shell u’mike’ instead of ‘mike’ pymongo decodes each bson string python unicode string, not regular str."

it seems bit silly me database can store utf-8 encoded strings, return type in pymongo unicode, meaning first thing have every string document once again call encode('utf-8') on it. there way around this, i.e. telling pymongo not give me unicode give me raw str?

no, there no such feature in pymongo; every string decoded bson decoded utf-8. python represents string internally ucs-2 or other format, depending on python version. see code bson decoder extracts string.

in upcoming pymongo 3.x series may add features more flexible bson decoding allow developers optimize uncommon use cases this.

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...
