Methods

def _make_date_lookup_arg(self, value): DateMixin

Convert a date into a datetime when the date field is a DateTimeField.

When time zone support is enabled, `date` is assumed to be in the
current time zone, so that displayed items are consistent with the URL.

def _make_single_date_lookup(self, date): DateMixin

Get the lookup kwargs for filtering on a single date.

If the date field is a DateTimeField, we can't just filter on
date_field=date because that doesn't take the time into account.
