mongodb - python: converting unix/posix epoch timestamp to datetime (after monogdb, date_util json export) -


so received data stored in mongodb exported json via bson.json_util.dumps() function. when try reconvert datetime objects, none of usual parsers work. here's sample:

{ u'_group': 0, u'_range': u'', u'canon': 0, u'comment_id': 0, u'created': {u'$date': 1491468607000l}, u'description': u'' }

and dates this:

[{u'$date': 1491457629000l}, {u'$date': 1491458993000l}, {u'$date': 1491457072000l}, {u'$date': 1491457035000l}, {u'$date': 1491457330000l}, {u'$date': 1491458323000l}, {u'$date': 1491458147000l}, {u'$date': 1491458277000l}, {u'$date': 1491459839000l}, {u'$date': 1491466340000l}, {u'$date': 1491463804000l}, {u'$date': 1491464304000l}, {u'$date': 1491465145000l}, {u'$date': 1492073749000l}, {u'$date': 1492073750000l}, {u'$date': 1492075415000l}, {u'$date': 1492155813000l}, {u'$date': 1492608582000l}, {u'$date': 1492671698000l}, {u'$date': 1493001047000l}, {u'$date': 1493714117000l}]

my tests:

y = {u'$date': 1491457629000l} >>> y['$date'] 1491457629000l

and various failed attempts:

print(     datetime.datetime.fromtimestamp(         y['$date']     ).strftime('%y-%m-%d %h:%m:%s') )

valueerror: timestamp out of range platform localtime()/gmtime() function

from dateutil import parser parser.parse(str(y['$date']))

overflowerror: python int large convert c long

utc_time = datetime.datetime(1970, 1, 1) + datetime.timedelta(seconds=y['$date'])

overflowerror: date value out of range

it seems unix timestamp converter should able read this. why isn't working? need year , month, timezone specificity outside scope of demands.

note (to downvoter): not duplicate of converting epoch time milliseconds datetime because solution here use different json parser mirrors way converted out of mongodb, instead of trying reformat unrelated timestamp parser. had researched other link , found didn't solve problem.

have tried removing last 3 zeroes (dividing 1000)?

error seems coming conversion, value in milliseconds, python datetime.datetime.fromtimestamp expects seconds seems.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
