==================
Generic date views
==================

.. module:: django.views.generic.dates

Date-based generic views, provided in :mod:`django.views.generic.dates`, are
views for displaying drilldown pages for date-based data.

ArchiveIndexView
----------------

.. class:: ArchiveIndexView

    A top-level index page showing the "latest" objects, by date. Objects with
    a date in the *future* are not included unless you set ``allow_future`` to
    ``True``.

    **Ancestors (MRO)**

    * :class:`django.views.generic.dates.ArchiveIndexView`
    * :class:`django.views.generic.list.MultipleObjectTemplateResponseMixin`
    * :class:`django.views.generic.base.TemplateResponseMixin`
    * :class:`django.views.generic.dates.BaseArchiveIndexView`
    * :class:`django.views.generic.dates.BaseDateListView`
    * :class:`django.views.generic.list.MultipleObjectMixin`
    * :class:`django.views.generic.dates.DateMixin`
    * :class:`django.views.generic.base.View`

    **Notes**

    * Uses a default ``context_object_name`` of ``latest``.
    * Uses a default ``template_name_suffix`` of ``_archive``.
    * Defaults to providing ``date_list`` by year, but this can be altered to
      month or day using the attribute ``date_list_period``. This also applies
      to all subclass views.

YearArchiveView
---------------

.. class:: YearArchiveView

    A yearly archive page showing all available months in a given year. Objects
    with a date in the *future* are not displayed unless you set
    ``allow_future`` to ``True``.

    **Ancestors (MRO)**

    * :class:`django.views.generic.dates.YearArchiveView`
    * :class:`django.views.generic.list.MultipleObjectTemplateResponseMixin`
    * :class:`django.views.generic.base.TemplateResponseMixin`
    * :class:`django.views.generic.dates.BaseYearArchiveView`

    * :class:`django.views.generic.dates.DateMixin`
    * :class:`django.views.generic.base.View`

    .. attribute:: make_object_list

        A boolean specifying whether to retrieve the full list of objects for
        this year and pass those to the template. If ``True``, the list of
        objects will be made available to the context. If ``False``, the
        ``None`` queryset will be used as the object list. By default, this is
        ``False``.

    .. method:: get_make_object_list()

        Determine if an object list will be returned as part of the context.
        Returns :attr:`~YearArchiveView.make_object_list` by default.


    **Context**

    In addition to the context provided by
    :class:`django.views.generic.list.MultipleObjectMixin` (via
    :class:`django.views.generic.dates.BaseDateListView`), the template's
    context will be:

    * ``date_list``: A
      :meth:`DateQuerySet<django.db.models.query.QuerySet.dates>` object object
      containing all months that have objects available according to
      ``queryset``, represented as
      :class:`datetime.datetime<python:datetime.datetime>` objects, in
      ascending order.

    * ``year``: A :class:`~datetime.date` object
      representing the given year.

      .. versionchanged:: 1.5

      Previously, this returned a string.

    * ``next_year``: A :class:`~datetime.date` object
      representing the first day of the next year, according to
      :attr:`~BaseDateListView.allow_empty` and
      :attr:`~DateMixin.allow_future`.

      .. versionadded:: 1.5

    * ``previous_year``: A :class:`~datetime.date` object
      representing the first day of the previous year, according to
      :attr:`~BaseDateListView.allow_empty` and
      :attr:`~DateMixin.allow_future`.

      .. versionadded:: 1.5

    **Notes**

    * Uses a default ``template_name_suffix`` of ``_archive_year``.
