Django Jalali

This module gives you a DateField same as Django’s DateField but you can get and query data based on Jalali Date

Status

Dependencies

• jdatetime

• Django > 2.2

  Looking for Django 1.X support? Checkout 2.4.6 version in pypi.org

• Django REST Framework > 3.12 (If install with drf dependency)

Install

pip install django_jalali

To use DRF serializer field:

pip install django_jalali[drf]

Usage

1. Run :

$ django-admin startproject jalali_test

2. Start your app :

$ python manage.py startapp foo

3. Edit settings.py and add django_jalali and your foo to your INSTALLED_APPS (also config DATABASES setting)

   django_jalali should be added before your apps in order to work properly

4. Edit foo/models.py

from django.db import models
from django_jalali.db import models as jmodels


class Bar(models.Model):
    objects = jmodels.jManager()
    name = models.CharField(max_length=200)
    date = jmodels.jDateField()

    def __str__(self):
        return "%s, %s" % (self.name, self.date)


class BarTime(models.Model):
    objects = jmodels.jManager()
    name = models.CharField(max_length=200)
    datetime = jmodels.jDateTimeField()

    def __str__(self):
        return "%s, %s" % (self.name, self.datetime)

5. Run

$ python manage.py makemigrations
Migrations for 'foo':
  foo/migrations/0001_initial.py:
     - Create model Bar
     - Create model BarTime
$ python manage.py migrate
Running migrations:
    Applying foo.0001_initial... OK

>>> Bar.objects.filter(date__gte="1390-5-12")
[<Bar: foo, 1390-05-12>]
>>> Bar.objects.filter(date='1363-8-01')
[]
>>> from foo.models import BarTime
>>> BarTime(name="Bar Time now", datetime=jdatetime.datetime(1380,8,2,12,12,12)).save()
>>> BarTime.objects.filter(datetime__lt= jdatetime.datetime(1380,8,2,12,12,12 ))
[]
>>> BarTime.objects.filter(datetime__lte= jdatetime.datetime(1380,8,2,12,12,12 ))
[<BarTime: Bar Time now, 1380-08-0212:12:12>]
>>> BarTime.objects.filter(datetime__gt='1380-08-02')
[<BarTime: Bar Time now, 1380-08-0212:12:12>]
>>> BarTime.objects.filter(datetime__gt=d)
[]
>>> BarTime.objects.filter(datetime__year=1380)
[<BarTime: Bar Time now, 1380-08-0212:12:12>]

Using Templatetags

1. You can use jformat filter to format your dates in templates:

{% load jformat %}
{{ my_date|jformat }} {# default formatting #}
{{ my_date|jformat:"%A %d %B %Y %H:%M" }} {# specific formatting #}

Admin Interface

1. Create foo/admin.py

from foo.models import Bar, BarTime
from django.contrib import admin

from django_jalali.admin.filters import JDateFieldListFilter

# you need import this for adding jalali calander widget
import django_jalali.admin as jadmin


class BarAdmin(admin.ModelAdmin):
    list_filter = (
        ('date', JDateFieldListFilter),
    )


admin.site.register(Bar, BarAdmin)


class BarTimeAdmin(admin.ModelAdmin):
    list_filter = (
        ('datetime', JDateFieldListFilter),
    )


admin.site.register(BarTime, BarTimeAdmin)

2. Config admin interface and fire up your django and enjoy using jalali date !

Django rest framework

There are serializer fields corresponding to jmodels.JDateField and jmodels.JDateTimeField for DRF:

from django_jalali.serializers.serializerfield import JDateField as JDateFieldSerializer
from rest_framework.serializers import ModelSerializer

from foo.models import Bar, BarTime


class JDateFieldSerialializer(ModelSerializer):
    date = JDateFieldSerializer()

    class Meta:
        model = Bar
        exclude = []

class JDateTimeFieldSerializer(ModelSerializer):
    datetime = JDateTimeField()

    class Meta:
        model = BarTime
        exclude = []

Locale

In order to get the date string in farsi you need to set the locale to fa_IR

There are two ways to do achieve that, you can use of the approaches based on your needs

• Run server with LC_ALL env:

$ LC_ALL=fa_IR python manage.py runserver

• Set the locale in settings.py

LANGUAGE_CODE = 'fa-ir'
import locale
locale.setlocale(locale.LC_ALL, "fa_IR.UTF-8")

Timezone Settings

From django_jalali version 3 and Django 2 you can use TIME_ZONE and USE_TZ settings to save datetime with project timezone
