Cara dan Atribut

date_fieldLink to this definition#

The name of the DateField or DateTimeField in the QuerySet’s model that the date-based archive should use to determine the list of objects to display on the page.

When time zone support is enabled and date_field is a DateTimeField, dates are assumed to be in the current time zone. Otherwise, the queryset could include objects from the previous or the next day in the end user's time zone.

Returns the name of the field that contains the date data that this view will operate on. Returns date_field by default.

get_allow_future()Link to this definition#

Determine whether to include "future" objects on this page, where "future" means objects in which the field specified in date_field is greater than the current date/time. Returns allow_future by default.

A base class that provides common behavior for all date-based views. There won't normally be a reason to instantiate BaseDateListView; instantiate one of the subclasses instead.

While this view (and its subclasses) are executing, self.object_list will contain the list of objects that the view is operating upon, and self.date_list will contain the list of dates for which data is available.

Returns a 3-tuple containing (date_list, object_list, extra_context).

date_list is the list of dates for which data is available. object_list is the list of objects. extra_context is a dictionary of context data that will be added to any context data provided by the MultipleObjectMixin.

get_date_list(queryset, date_type=None, ordering='ASC')Link to this definition#
