README
===================
django-yearlessdate
===================
Provides a Django model and form fields for dates that do not include years.
One use case is to collect birthdays without requiring the year of birth.
|build-status| |python-versions| |django-versions| |wheel| |license|
Prerequisites
=============
- Django 1.8 - 1.11, 2.0
- Python 2.7, 3.6
(Other versions may function, but are untested.)
Installation
============
.. code-block:: console
pip install django-yearlessdate
Usage
=====
The package provides two model fields, ``YearlessDateField`` and ``YearField``.
YearlessDateField
-----------------
``YearlessDateField`` stores a date without a year: January 1st, for example.
Its default widget consists of two dropdowns, one for a day and one for the month.
It will only allow potentially valid dates. For example, a user won't be able to set
the date to April 31st. February 29th is counted as a valid date.
Here's an example ``models.py`` that declares a model with a required yearless date::
from django.db import models
from djangoyearlessdate.models import YearlessDateField
class MyModel(models.Model):
birthday = YearlessDateField()
The values of ``YearlessDateField`` on the model instances can be accessed like so:
>>> a = MyModel.objects.get(id=1)
>>> a
>>> a.birthday.day
4
>>> a.birthday.month
8
>>> print a.birthday
4 August
They can also be compared or sorted as would be expected, for example:
>>> m = MyModel.objects.all()
>>> m
[, ]
>>> m[0].birthday > m[1].birthday
True
>>> m.order_by('birthday')
[, ]
YearField
---------
``YearField`` is a very simple model field that stores the year as an integer,
and ensures the year provided lies between 1900 and 2200::
from django.db import models
from djangoyearlessdate.models import YearField
class MyModel(models.Model):
year = YearField(null=True, blank=True)
Use of ``YearField`` is *not recommended* due to its lack of configurability.
You're almost certainly better of using a ``SmallIntegerField`` in combination
with a ``MinValueValidator`` and a ``MaxValueValidator``.
