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

6. Test it

>>> from foo.models import BarTime
>>> BarTime(name="Bar Time now", datetime=jdatetime.datetime(1380,8,2,12,12,12)).save()
>>> BarTime.objects.filter(datetime__date=jdatetime.datetime(1380,8,2,12,12,12))
[<BarTime: Bar Time now, 1380-08-0212:12:12>]
>>> BarTime.objects.filter(datetime__date=jdatetime.date(1380,8,2))
[<BarTime: Bar Time now, 1380-08-0212:12:12>]
>>> BarTime.objects.filter(datetime__date="1380-08-02")
[<BarTime: Bar Time now, 1380-08-0212:12:12>]
>>> 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>]

⚠️ __month filter is not supported as explained in here

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 to import this for adding jalali calendar 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, JDateTimeField
from rest_framework.serializers import ModelSerializer

from foo.models import Bar, BarTime


class JDateFieldSerialializer(ModelSerializer):
    date = JDateField()

    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")

• If using Docker, add the following to your Dockerfile:

FROM python:3.11-slim-bookworm

RUN apt-get update && apt-get -y install locales && \
 sed -i -e 's/# fa_IR UTF-8/fa_IR UTF-8/' /etc/locale.gen && \
 dpkg-reconfigure --frontend=noninteractive locales

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

Development

You can contribute to this project forking it from GitHub and sending pull requests.

First fork the repository and then clone it:

$ git clone [email protected]:<you>/django-jalali.git

Initialize a virtual environment for development purposes:

$ python -m venv django_jalali_env
$ source ~/django_jalali_env/bin/activate

Then install the necessary requirements:

$ cd django-jalali
$ pip install -r requirements-test.txt

Unit tests are located in the tests folder and can be easily run with the pytest tool:

$ pytest

Before committing, you can run all the above tests against all supported Python and Django versions with tox. You need to install tox first:

$ pip install tox

And then you can run all tests:

$ tox

If you wish to limit the testing to specific environment(s), you can parametrize the tox run:

$ tox -e py39-django42
