A Django app providing database and form fields for pytz timezone objects.

Examples

Database Field

import pytz
from django.db import models
from timezone_field import TimeZoneField

class MyModel(models.Model):
    tz1 = TimeZoneField(default='Europe/London')            # defaults supported
    tz2 = TimeZoneField()                                   # in ModelForm displays like "America/Los Angeles"
    tz3 = TimeZoneField(choices_display='WITH_GMT_OFFSET')  # in ModelForm displays like "GMT-08:00 America/Los Angeles"

my_model = MyModel(
    tz1='America/Los_Angeles',    # assignment of a string
    tz2=pytz.timezone('Turkey'),  # assignment of a pytz.DstTzInfo
    tz3=pytz.UTC,                 # assignment of pytz.UTC singleton
)
my_model.full_clean() # validates against pytz.common_timezones by default
my_model.save()       # values stored in DB as strings
my_model.tz1          # values retrieved as pytz objects: <DstTzInfo 'America/Los_Angeles' PST-1 day, 16:00:00 STD>

Form Field

from django import forms
from timezone_field import TimeZoneFormField

class MyForm(forms.Form):
    tz = TimeZoneFormField()                                    # displays like "America/Los Angeles"
    tz2 = TimeZoneFormField(choices_display='WITH_GMT_OFFSET')  # displays like "GMT-08:00 America/Los Angeles"

my_form = MyForm({'tz': 'America/Los_Angeles'})
my_form.full_clean()        # validates against pytz.common_timezones by default
my_form.cleaned_data['tz']  # values retrieved as pytz objects: <DstTzInfo 'America/Los_Angeles' PST-1 day, 16:00:00 STD>

REST Framework Serializer Field

import pytz
from rest_framework import serializers
from timezone_field.rest_framework import TimeZoneSerializerField

class MySerializer(serializers.Serializer):
    tz1 = TimeZoneSerializerField()
    tz2 = TimeZoneSerializerField()

my_serializer = MySerializer(data={
    'tz1': 'America/Argentina/Buenos_Aires',
    'tz2': pytz.timezone('America/Argentina/Buenos_Aires'),
})
my_serializer.is_valid()            # true
my_serializer.validated_data['tz1'] # <DstTzInfo 'America/Argentina/Buenos_Aires' LMT-1 day, 20:06:00 STD>
my_serializer.validated_data['tz2'] # <DstTzInfo 'America/Argentina/Buenos_Aires' LMT-1 day, 20:06:00 STD>

    • For form field, changed default list of accepted timezones from pytz.all_timezones to pytz.common_timezones, to match DB field behavior.

  • 1.1 (2014-10-05)

    • Django 1.7 compatibility

    • Added support for formatting choices kwarg as [[<str>, <str>], …], in addition to previous format of [[<pytz.timezone>, <str>], …].

    • Changed default list of accepted timezones from pytz.all_timezones to pytz.common_timezones. If you have timezones in your DB that are in pytz.all_timezones but not in pytz.common_timezones, this is a backward-incompatible change. Old behavior can be restored by specifying choices=[(tz, tz) for tz in pytz.all_timezones] in your model definition.

  • 1.0 (2013-08-04)

    • Initial release as timezone_field.

Running the Tests

  1. Install tox.

  2. From the repository root, run

    tox

    Postgres will need to be running locally, and sqlite will need to be installed in order for tox to do its job.
