The following values are supported: - `'%U'`: Based on the United States week system where the week begins on Sunday. This is the default value. - `'%W'`: Similar to `'%U'`, except it assumes that the week begins on Monday. This is not the same as the ISO 8601 week number. - `'%V'`: ISO 8601 week number where the week begins on Monday. **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 ``` **例 myapp/urls.py**: ``` from django.urls import path from myapp.views import ArticleWeekArchiveView urlpatterns = [ # Example: /2012/week/23/ path( "/week//", ArticleWeekArchiveView.as_view(), name="archive_week", ), ] ``` **Example myapp/article\_archive\_week.html**: ```html+django

Week {{ week|date:'W' }}

    {% for article in object_list %}
  • {{ article.pub_date|date:"F j, Y" }}: {{ article.title }}
    • {% endfor %}

{% if previous_week %} Previous Week: {{ previous_week|date:"W" }} of year {{ previous_week|date:"Y" }} {% endif %} {% if previous_week and next_week %}--{% endif %} {% if next_week %} Next week: {{ next_week|date:"W" }} of year {{ next_week|date:"Y" }} {% endif %}

``` In this example, you are outputting the week number. Keep in mind that week numbers computed by the [`date`](/ja/4.2/ref/templates/builtins/#std-templatefilter-date) template filter with the `'W'` format character are not always the same as those computed by [`strftime()`](https://docs.python.org/3/library/time.html#time.strftime) and [`strptime()`](https://docs.python.org/3/library/time.html#time.strptime) with the `'%W'` format string. For year 2015, for example, week numbers output by [`date`](/ja/4.2/ref/templates/builtins/#std-templatefilter-date) are higher by one compared to those output by [`strftime()`](https://docs.python.org/3/library/time.html#time.strftime). There isn't an equivalent for the `'%U'` [`strftime()`](https://docs.python.org/3/library/time.html#time.strftime) format string in [`date`](/ja/4.2/ref/templates/builtins/#std-templatefilter-date). Therefore, you should avoid using [`date`](/ja/4.2/ref/templates/builtins/#std-templatefilter-date) to generate URLs for `WeekArchiveView`. ## `DayArchiveView` #### `class DayArchiveView` 与えられた日の中で有効な全オブジェクトを表示する、日次のアーカイブページです。`allow_future` を `True` にセットしない限り、未来の日付に対するオブジェクトがするかどうかにかかわらず、未来の日付は 404 エラーを返します。 **継承元 (MRO)** - [`django.views.generic.list.MultipleObjectTemplateResponseMixin`](/ja/4.2/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectTemplateResponseMixin) - [`django.views.generic.base.TemplateResponseMixin`](/ja/4.2/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin) - [`django.views.generic.dates.BaseDayArchiveView`](#django.views.generic.dates.BaseDayArchiveView) - [`django.views.generic.dates.YearMixin`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.YearMixin) - [`django.views.generic.dates.MonthMixin`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.MonthMixin) - [`django.views.generic.dates.DayMixin`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.DayMixin) - [`django.views.generic.dates.BaseDateListView`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.BaseDateListView) - [`django.views.generic.list.MultipleObjectMixin`](/ja/4.2/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin) - [`django.views.generic.dates.DateMixin`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.DateMixin) - [`django.views.generic.base.View`](/ja/4.2/ref/class-based-views/base/#django.views.generic.base.View) **コンテキスト** In addition to the context provided by [`MultipleObjectMixin`](/ja/4.2/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin) (via [`BaseDateListView`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.BaseDateListView)), the template's context will be: - `day`: A [`date`](https://docs.python.org/3/library/datetime.html#datetime.date) object representing the given day. - `next_day`: A [`date`](https://docs.python.org/3/library/datetime.html#datetime.date) object representing the next day, according to [`allow_empty`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.BaseDateListView.allow_empty) and [`allow_future`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.DateMixin.allow_future). - `previous_day`: A [`date`](https://docs.python.org/3/library/datetime.html#datetime.date) object representing the previous day, according to [`allow_empty`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.BaseDateListView.allow_empty) and [`allow_future`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.DateMixin.allow_future). - `next_month`: A [`date`](https://docs.python.org/3/library/datetime.html#datetime.date) object representing the first day of the next month, according to [`allow_empty`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.BaseDateListView.allow_empty) and [`allow_future`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.DateMixin.allow_future). - `previous_month`: A [`date`](https://docs.python.org/3/library/datetime.html#datetime.date) object representing the first day of the previous month, according to [`allow_empty`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.BaseDateListView.allow_empty) and [`allow_future`](/ja/4.2/ref/class-based-views/mixins-date-based/#django.views.generic.dates.DateMixin.allow_future). **ノート** - Uses a default `template_name_suffix` of `_archive_day`. **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 ``` **例 myapp/urls.py**: ``` from django.urls import path from myapp.views import ArticleDayArchiveView urlpatterns = [ # Example: /2012/nov/10/ path( "///", ArticleDayArchiveView.as_view(), name="archive_day", ), ] ``` **Example myapp/article\_archive\_day.html**: ```html+django
