Install

.. code:: bash

pip install django_jalali

To use DRF serializer field:

.. code:: bash

pip install django_jalali[drf]

Usage

1. Run :

.. code:: bash

$ django-admin startproject jalali_test

2. Start your app :

.. code:: bash

$ 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_

.. code:: python

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

.. code:: bash

$ 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:

.. code:: python

{% 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_

.. code:: python

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:

.. code:: python

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:

.. code:: shell

$ LC_ALL=fa_IR python manage.py runserver

• Set the locale in settings.py

.. code:: python

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

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

.. code:: 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:

.. code:: shell

$ git clone git@github.com:<you>/django-jalali.git

Initialize a virtual environment for development purposes:

.. code:: shell

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

Then install the necessary requirements:

.. code:: shell

$ 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:

.. code:: shell

$ 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:

.. code:: shell

$ pip install tox

And then you can run all tests:

.. code:: shell

$ tox

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

.. code:: shell

$ tox -e py39-django42
