Generic date ビューLink to this heading

日付ベースの汎用ビュー (django.views.generic.dates 内で提供されています) は、日付ベースのデータのために、ドリルダウンページを描画するためのビューです。

注釈

このページの例のいくつかは、myapp/models.py 内で下記の通り Article モデルが定義されていると仮定します:

Code

from django.db import models
from django.urls 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`Link to this heading

class ArchiveIndexViewLink to this definition

"最新の"オブジェクトを、日付によって表示するトップレベルのインデックスページです。allow_future を True にセットしない限り、未来の日付のオブジェクトは含まれません。

継承元 (MRO)

コンテキスト

(django.views.generic.dates.BaseDateListView を通じた) django.views.generic.list.MultipleObjectMixin によって提供されたコンテキストに加えて、テンプレートのコンテキストは以下のようになります:

date_list: queryset に従ってオブジェクトを利用可能にするすべての年を含む QuerySet オブジェクトです。datetime.datetime オブジェクトとして表され、降順で表示されます。

ノート

デフォルトの 最新 の context_object_name を使います。
デフォルトの _archive の template_name_suffix を使います。
年によって date_list を提供する動作がデフォルトですが、date_list_period 属性を用いた月や日に変更できます。これは、すべてのサブクラスのビューに適用されます。

例 myapp/urls.py:

Code

from django.urls import path
from django.views.generic.dates import ArchiveIndexView

from myapp.models import Article

urlpatterns = [
    path('archive/',
         ArchiveIndexView.as_view(model=Article, date_field="pub_date"),
         name="article_archive"),
]

例 myapp/article_archive.html:

Django template

<ul>
    {% for article in latest %}
        <li>{{ article.pub_date }}: {{ article.title }}</li>
    {% endfor %}
</ul>

これは、すべての記事 (article) を出力します。

class YearArchiveViewLink to this definition

与えられた年の中で有効な月を表示する、年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、未来の日付を伴うオブジェクトは表示されません。

make_object_listLink to this definition: 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.

get_make_object_list()Link to this definition: Determine if an object list will be returned as part of the context. Returns make_object_list by default.

コンテキスト

In addition to the context provided by MultipleObjectMixin (via BaseDateListView), the template's context will be:

month: A date object representing the given month.
next_month: A date object representing the first day of the next month, according to allow_empty and allow_future.
previous_month: A date object representing the first day of the previous month, according to allow_empty and allow_future.

from myapp.models import Article

class ArticleMonthArchiveView(MonthArchiveView):
    queryset = Article.objects.all()
    date_field = "pub_date"

    # Example: /2012/08/
    path('<int:year>/<int:month>/',
         ArticleMonthArchiveView.as_view(month_format='%m'),
         name="archive_month_numeric"),

    path('<int:year>/<str:month>/',
         ArticleMonthArchiveView.as_view(),
         name="archive_month"),

        <li>{{ article.pub_date|date:"F j, Y" }}: {{ article.title }}</li>
    {% endfor %}

    {% if previous_month %}
        Previous Month: {{ previous_month|date:"F Y" }}

`WeekArchiveView`Link to this heading

class WeekArchiveViewLink to this definition

与えられた週の中で有効な全オブジェクトを表示する、週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、未来の日付を伴うオブジェクトは表示されません。

継承元 (MRO)

コンテキスト

In addition to the context provided by MultipleObjectMixin (via BaseDateListView), the template's context will be:

week: A date object representing the first day of the given week.
next_week: A date object representing the first day of the next week, according to allow_empty and allow_future.
previous_week: A date object representing the first day of the previous week, according to allow_empty and allow_future.

ノート

Uses a default template_name_suffix of _archive_week.
The week_format attribute is a strptime() format string used to parse the week number. 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.
  
  New in Django 3.2
  Support for the '%V' week format was added.

Example myapp/views.py:

Code

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:

Code

from django.urls import path

from myapp.views import ArticleWeekArchiveView

urlpatterns = [
    # Example: /2012/week/23/
    path('<int:year>/week/<int:week>/',
         ArticleWeekArchiveView.as_view(),
         name="archive_week"),
]

Example myapp/article_archive_week.html:

Django template

<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:"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 %}
</p>

In this example, you are outputting the week number. Keep in mind that week numbers computed by the date template filter with the 'W' format character are not always the same as those computed by strftime() and strptime() with the '%W' format string. For year 2015, for example, week numbers output by date are higher by one compared to those output by strftime(). There isn't an equivalent for the '%U' strftime() format string in date. Therefore, you should avoid using date to generate URLs for WeekArchiveView.
