jsondate's Introduction

jsondate

Sick of rewriting the same JSON datetime handling code for each project? jsondate is a drop-in replacement for Python's standard json library that adds sensible handling of datetime and date objects.

jsondate uses ISO8601 for encoding datetime objects and the date-specific part of ISO6801 for encoding date objects.

Example:

import datetime
import jsondate as json

>>> data = json.dumps(dict(created_at=datetime.datetime(2012, 10, 31)))
'{"created_at": "2012-10-31T00:00:00Z"}'

>>> json.loads(data)
{u'created_at': datetime.datetime(2012, 10, 31, 0, 0)}

>>> date = json.dumps(dict(date=datetime.date(2012, 10, 31)))
'{"date": "2012-10-31"}'

>>> json.loads(data)
{u'created_at': datetime.date(2012, 10, 31)}

Unicode Empty Strings

The json standard library module will return unicode objects for all strings except empty strings, which are returned as str objects.

This inconsistency can be annoying when using libraries that expect all input to be unicode.

jsondate fixes this by returning empty-strings as unicode objects as well.

jsondate's Issues

decode every datetime string to datetime object is not always the best option

if I have a field like datetime_str which I expected it to be exactly a datetime string . but by using jsondate. this field will always be decoded to datetime object... which is not what I want.

{ 'a': '20130101', 'b': datetime(2012,01,01) }
dumps_str = dumps(  {'a': '20130101',      do your magic on 'b' } )
loads( dumps_str )  # the same,  do your magic on 'b' only

maybe this this the main reason why pymongo bson.json_util convert datetime object into a dict instead.

   {'a': 'hi' , 'b': datetime(2011,1,1)} 
 => 
   {'a': 'hi', 'b': {'$date': '20110101' } }

Transfer project to new maintainer

Hello,

I'm the director of Free Law Project (https://github.com/freelawproject). We've become dependent on jsondate and we want to upgrade it to py3. This library feels pretty much abandoned, so I wonder if we can take it over somehow. It's a very small library, so I think that'd just mean:

Figuring out how to transfer the code to us on Github
Figuring out how to transfer the pypi things to us so we can upload new versions
Working out any licensing issues (looks like it's MIT, so should be easy).

We've already vendored the code in freelawproject/juriscraper#249 and are considering a fork, but it'd be much better to get this one fixed and alive again.

Thank you,

Mike

Problem decoding RavenDB content when attribute value is a dict

Results returned from RavenDB contain a dict entry called @metadata which has a value which itself is a dict:
{'@metadata': {'Temp-Index-Score': 1.41421354}, 'document_id': '104068/1951-01-01', ...
This throws in jsondate__init.datetime_decoder, first line:
for key, value in dict.iteritems():
with AttributeError: 'dict' object has no attribute 'iteritems'

The problem appears to be in the scanner, but I can't pinpoint any further as the working of make_scanner are a bit opaque.

load()/loads() doesn't handle date/datetime values that aren't contained in a dict

load()/loads() doesn't handle date/datetime values that aren't contained in a dict. It appears that the object_hook callback is only useful for objects, not for other types. From what I can see, the json module only offers hooks for objects, ints and floats, not strings. :(

>>> import datetime
>>> import jsondate as json
>>> date = datetime.date(2014, 12, 22)
>>> dumped = json.dumps(date)
>>> print dumped
"2014-12-22"
>>> loaded = json.loads(dumped)
>>> print loaded
2014-12-22
>>> date = [datetime.date(2014, 12, 22)]
>>> dumped = json.dumps(date)
>>> print dumped
["2014-12-22"]
>>> loaded = json.loads(dumped)
>>> print loaded
[u'2014-12-22']

Looks like this would be fairly easy. There's even a fork that seems to already be working on this.
