Django field for storing dates without years.
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.
- Django 1.8 - 1.11, 2.0
- Python 2.7, 3.6
(Other versions may function, but are untested.)
pip install django-yearlessdate
The package provides two model fields, YearlessDateField and YearField.
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 <MyModel: 4 August 2011> >>> 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 [<MyModel: 4 August 2011>, <MyModel: 30 June 2013>] >>> m.birthday > m.birthday True >>> m.order_by('birthday') [<MyModel: 30 June 2013>, <MyModel: 4 August 2011>]
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.
