django-nepkit 0.1.0

Django Nepali date, time, phone, and address fields with helpers.

django-nepkit

django-nepkit is a lightweight Django utility package for Nepali projects. It provides model fields, validators, and admin helpers for:

• Bikram Sambat (BS) date, time, and datetime
• Nepali phone number validation
• Chained address selects (province → district → municipality)

It also includes Django admin enhancements:

• NepaliModelAdmin automatically wires the Nepali datepicker
• NepaliDateFilter for filtering BS dates by year

Optional Django REST Framework (DRF) serializer fields are available (install with django-nepkit[drf]).

Notes

• The package depends on py-nepali.
• The date picker UI is implemented from sajanm/nepali-date-picker.

Setup

Add to INSTALLED_APPS

INSTALLED_APPS = [
    # ...

    "django_nepkit",
]

Quick Start

# models.py
from django.db import models
from django_nepkit import NepaliDateField, NepaliDateTimeField, NepaliPhoneNumberField

class Person(models.Model):
    name = models.CharField(max_length=100)
    birth_date = NepaliDateField()
    created_at = NepaliDateTimeField(auto_now_add=True)
    phone_number = NepaliPhoneNumberField()

# admin.py
from django.contrib import admin
from django_nepkit import NepaliModelAdmin
from .models import Person

@admin.register(Person)
class PersonAdmin(NepaliModelAdmin):
    list_display = ("name", "birth_date", "created_at", "phone_number")

NepaliModelAdmin automatically loads the Nepali datepicker assets and applies the widget—no custom forms required.

Model Fields

NepaliDateField (BS date)

Stores a BS date in the DB as a string (YYYY-MM-DD). In Python, it returns/accepts nepali.datetime.nepalidate.

from django_nepkit import NepaliDateField

class Event(models.Model):
    event_date = NepaliDateField()

Notes:

• Stored as a string, not SQL DATE
• Accepts BS strings like "2081-10-15", nepalidate, and AD datetime.date (converted to BS)

---

NepaliDateTimeField (BS datetime)

Stores a BS datetime string (YYYY-MM-DD HH:MM:SS) in the DB and uses nepalidatetime in Python.

from django_nepkit import NepaliDateTimeField

class Log(models.Model):
    created_at = NepaliDateTimeField(auto_now_add=True)
    updated_at = NepaliDateTimeField(auto_now=True)

---

NepaliTimeField

A normal Django TimeField for consistency.

from django_nepkit import NepaliTimeField

class Shift(models.Model):
    start_time = NepaliTimeField()

---

NepaliPhoneNumberField

A CharField with Nepali phone number validation.

from django_nepkit import NepaliPhoneNumberField

class Contact(models.Model):
    phone_number = NepaliPhoneNumberField()

---

Address Fields (Chained Selects)

Chained fields: province → district → municipality.

from django.db import models
from django_nepkit import ProvinceField, DistrictField, MunicipalityField

class Address(models.Model):
    province = ProvinceField()
    district = DistrictField()
    municipality = MunicipalityField()

URLs required for chaining

# urls.py
from django.urls import include, path

urlpatterns = [
    # ...
    path("nepkit/", include("django_nepkit.urls")),
]

---
