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.
|
|
|
|
.. note::
|
|
|
|
Some of the examples on this page assume that an ``Article`` model has been
|
|
defined as follows in ``myapp/models.py``::
|
|
|
|
from django.db import models
|
|
from django.core.urlresolvers import reverse
|
|
|
|
class Article(models.Model):
|
|
title = models.CharField(max_length=200)
|
|
pub_date = models.DateField()
|
|
|
|
def get_absolute_url(self):
|
|
return reverse('article-detail', kwargs={'pk': self.pk})
|
|
|
|
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.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`
|
|
|
|
**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
|
|
containing all years that have objects available according to
|
|
``queryset``, represented as
|
|
:class:`datetime.datetime<python:datetime.datetime>` objects, in
|
|
descending order.
|
|
|
|
**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.
|
|
|
|
**Example myapp/urls.py**::
|
|
|
|
from django.conf.urls import url
|
|
from django.views.generic.dates import ArchiveIndexView
|
|
|
|
from myapp.models import Article
|
|
|
|
urlpatterns = [
|
|
url(r'^archive/$',
|
|
ArchiveIndexView.as_view(model=Article, date_field="pub_date"),
|
|
name="article_archive"),
|
|
]
|
|
|
|
**Example myapp/article_archive.html**:
|
|
|
|
.. code-block:: html+django
|
|
|
|
<ul>
|
|
{% for article in latest %}
|
|
<li>{{ article.pub_date }}: {{ article.title }}</li>
|
|
{% endfor %}
|
|
</ul>
|
|
|
|
This will output all articles.
|
|
|
|
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``.
|
|
|
|

|
|
|
|
.. 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.

**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:
|
|
|
|
* ``week``: A :class:`~datetime.date` object
|
|
representing the first day of the given week.
|
|
|
|
* ``next_week``: A :class:`~datetime.date` object
|
|
representing the first day of the next week, according to
|
|
:attr:`~BaseDateListView.allow_empty` and
|
|
:attr:`~DateMixin.allow_future`.
|
|
|
|
* ``previous_week``: A :class:`~datetime.date` object
|
|
representing the first day of the previous week, according to
|
|
:attr:`~BaseDateListView.allow_empty` and
|
|
:attr:`~DateMixin.allow_future`.
|
|
|
|
**Notes**
|
|
|
|
* Uses a default ``template_name_suffix`` of ``_archive_week``.
|
|
|
|
**Example myapp/views.py**::
|
|
|
|
from django.views.generic.dates import WeekArchiveView
|
|
|
|
from myapp.models import Article
|
|
|
|
class ArticleWeekArchiveView(WeekArchiveView):
|
|
queryset = Article.objects.all()
|
|
date_field = "pub_date"
|
|
make_object_list = True
|
|
week_format = "%W"
|
|
allow_future = True
|
|
|
|
**Example myapp/urls.py**::
|
|
|
|
from django.conf.urls import url
|
|
|
|
from myapp.views import ArticleWeekArchiveView
|
|
|
|
urlpatterns = [
|
|
# Example: /2012/week/23/
|
|
url(r'^(?P<year>[0-9]{4})/week/(?P<week>[0-9]+)/$',
|
|
ArticleWeekArchiveView.as_view(),
|
|
name="archive_week"),
|
|
]
|
|
|
|
**Example myapp/article_archive_week.html**:
|
|
|
|
.. code-block:: html+django
|
|
|
|
<h1>Week {{ week|date:'W' }}</h1>
|
|
|
|
<ul>
|
|
{% for article in object_list %}
|
|
<li>{{ article.pub_date|date:"F j, Y" }}: {{ article.title }}</li>
|
|
{% endfor %}
|
|
</ul>
|
|
|
|
<p>
|
|
{% if previous_week %}
|
|
Previous Week: {{ previous_week|date:"F Y" }}
|
|
{% endif %}
|
|
{% if previous_week and next_week %}--{% endif %}
|
|
{% if next_week %}
|
|
Next week: {{ next_week|date:"F Y" }}
|
|
{% endif %}
|
|
</p>
|
|
|
|
In this example, you are outputting the week number. The default
|
|
``week_format`` in the ``WeekArchiveView`` uses week format ``'%U'``
|
|
which is based on the United States week system where the week begins on a
|
|
Sunday. The ``'%W'`` format uses the ISO week format and its week
|
|
begins on a Monday. The ``'%W'`` format is the same in both the
|
|
:func:`~time.strftime` and the :tfilter:`date`.
|
|
|
|
However, the :tfilter:`date` template filter does not have an equivalent
|
|
output format that supports the US based week system. The :tfilter:`date`
|
|
filter ``'%U'`` outputs the number of seconds since the Unix epoch.
|
|
|
|
DayArchiveView
|
|
--------------
|
|
|
|
.. class:: DayArchiveView
|
|
|
|
A day archive page showing all objects in a given day. Days in the future
|
|
throw a 404 error, regardless of whether any objects exist for future days,
|
|
unless you set ``allow_future`` to ``True``.

**Example myapp/views.py**::
|
|
|
|
from django.views.generic.dates import TodayArchiveView
|
|
|
|
from myapp.models import Article
|
|
|
|
class ArticleTodayArchiveView(TodayArchiveView):
|
|
queryset = Article.objects.all()
|
|
date_field = "pub_date"
|
|
make_object_list = True
|
|
allow_future = True
|
|
|
|
**Example myapp/urls.py**::

from django.conf.urls import url
|
|
|
|
from myapp.views import ArticleTodayArchiveView
|
|
|
|
urlpatterns = [
|
|
url(r'^today/$',
|
|
ArticleTodayArchiveView.as_view(),
|
|
name="archive_today"),
|
|
]
|
|
|
|
.. admonition:: Where is the example template for ``TodayArchiveView``?
|
|
|
|
This view uses by default the same template as the
|
|
:class:`~DayArchiveView`, which is in the previous example. If you need
|
|
a different template, set the ``template_name`` attribute to be the
|
|
name of the new template.
|
|
|
|
DateDetailView
|
|
--------------
|
|
|
|
.. class:: DateDetailView
|
|
|
|
A page representing an individual object. If the object has a date value in
|
|
the future, the view will throw a 404 error by default, unless you set
|
|
``allow_future`` to ``True``.
