The DateField
(documentation)
class in the django.forms module in the Django
web framework provides a mechanism for safely handling
dates, but not times, as input from an HTTP POST request. The request is
typically generated by an HTML form
created from a Django web application.
django-filter (project documentation and PyPI page) makes it easier to filter down querysets from the Django ORM by providing common bits of boilerplate code. django-filter is provided as open source.
