Date-based generic views, provided in django.views.generic.dates, are views for displaying drilldown pages for date-based data.
Примечание
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})
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.

Context
In addition to the context provided by django.views.generic.list.MultipleObjectMixin (via django.views.generic.dates.BaseDateListView), the template’s context will be:
Notes
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/$',
ArchiveIndexView.as_view(model=Article, date_field="pub_date"),
name="article_archive"),
]
Example myapp/article_archive.html:
<ul>
{% for article in latest %}
<li>{{ article.pub_date }}: {{ article.title }}</li>
{% endfor %}
</ul>
This will output all articles.
A yearly archive page showing all available months in a given year. Objects with a date in the future are not displayed unless you set allow_future to True.
Ancestors (MRO)
A boolean specifying whether to retrieve the full list of objects for this year and pass those to the template. If True, the list of objects will be made available to the context. If False, the None queryset will be used as the object list. By default, this is False.
Determine if an object list will be returned as part of the context. Returns make_object_list by default.
Context
In addition to the context provided by django.views.generic.list.MultipleObjectMixin (via django.views.generic.dates.BaseDateListView), the template’s context will be:
Notes
Example myapp/views.py:
from django.views.generic.dates import YearArchiveView
from myapp.models import Article
class ArticleYearArchiveView(YearArchiveView):
queryset = Article.objects.all()
date_field = "pub_date"
make_object_list = True
allow_future = True
Example myapp/urls.py:
from django.conf.urls import url
from myapp.views import ArticleYearArchiveView
urlpatterns = [
url(r'^(?P<year>[0-9]{4})/$',
ArticleYearArchiveView.as_view(),
name="article_year_archive"),
]
Example myapp/article_archive_year.html:
<ul>
{% for date in date_list %}
<li>{{ date|date }}</li>
{% endfor %}
</ul>
<div>
<h1>All Articles for {{ year|date:"Y" }}</h1>
{% for obj in object_list %}
<p>
{{ obj.title }} - {{ obj.pub_date|date:"F j, Y" }}
</p>
{% endfor %}
</div>
A monthly archive page showing all objects in a given month. Objects with a date in the future are not displayed unless you set allow_future to True.

Context
In addition to the context provided by MultipleObjectMixin (via BaseDateListView), the template’s context will be:
Notes
Example myapp/views.py:
from django.views.generic.dates import MonthArchiveView
from myapp.models import Article
class ArticleMonthArchiveView(MonthArchiveView):
queryset = Article.objects.all()
date_field = "pub_date"
allow_future = True
Example myapp/urls.py:
from django.conf.urls import url
from myapp.views import ArticleMonthArchiveView
urlpatterns = [
# Example: /2012/aug/
url(r'^(?P<year>[0-9]{4})/(?P<month>[-\w]+)/$',
ArticleMonthArchiveView.as_view(),
name="archive_month"),
# Example: /2012/08/
url(r'^(?P<year>[0-9]{4})/(?P<month>[0-9]+)/$',
ArticleMonthArchiveView.as_view(month_format='%m'),
name="archive_month_numeric"),
]
Example myapp/article_archive_month.html:
<ul>
{% for article in object_list %}
<li>{{ article.pub_date|date:"F j, Y" }}: {{ article.title }}</li>
{% endfor %}
</ul>
<p>
{% if previous_month %}
Previous Month: {{ previous_month|date:"F Y" }}
{% endif %}
{% if next_month %}
Next Month: {{ next_month|date:"F Y" }}
{% endif %}
</p>
A weekly archive page showing all objects in a given week. Objects with a date in the future are not displayed unless you set allow_future to True.

Context
In addition to the context provided by MultipleObjectMixin (via BaseDateListView), the template’s context will be:
Notes
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"
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:
<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 strftime() and the date.
However, the date template filter does not have an equivalent output format that supports the US based week system. The date filter '%U' outputs the number of seconds since the Unix epoch.
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 DayArchiveView
from myapp.models import Article
class ArticleDayArchiveView(DayArchiveView):
queryset = Article.objects.all()
date_field = "pub_date"
allow_future = True
Example myapp/urls.py:
from django.conf.urls import url
from myapp.views import ArticleDayArchiveView
urlpatterns = [
# Example: /2012/nov/10/
url(r'^(?P<year>[0-9]{4})/(?P<month>[-\w]+)/(?P<day>[0-9]+)/$',
ArticleDayArchiveView.as_view(),
name="archive_day"),
]
Example myapp/article_archive_day.html:
<h1>{{ day }}</h1>
<ul>
{% for article in object_list %}
<li>{{ article.pub_date|date:"F j, Y" }}: {{ article.title }}</li>
{% endfor %}
</ul>
<p>
{% if previous_day %}
Previous Day: {{ previous_day }}
{% endif %}
{% if previous_day and next_day %}--{% endif %}
{% if next_day %}
Next Day: {{ next_day }}
{% endif %}
</p>
A day archive page showing all objects for today. This is exactly the same as django.views.generic.dates.DayArchiveView, except today’s date is used instead of the year/month/day arguments.

Notes
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"
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"),
]
Where is the example template for TodayArchiveView?
This view uses by default the same template as the 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.
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.

Примечание
All of the generic views listed above have matching Base views that only differ in that they do not include the MultipleObjectTemplateResponseMixin (for the archive views) or SingleObjectTemplateResponseMixin (for the DateDetailView):
