# Generic display ビュー

以下の2つの汎用クラスベースビューは、データを描画 (display)するようにデザインされています。多くのプロジェクトで、これらは最も広範に使われるビューとなります。

## Detail Views

#### `class django.views.generic.detail.DetailView`

このビューが動作している間、`self.object` はビューが操作しているオブジェクトを含みます。

**継承元 (MRO)**

このメソッドは、以下のビューからメソッドと属性を継承しています:

- [`django.views.generic.detail.SingleObjectTemplateResponseMixin`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectTemplateResponseMixin)
- [`django.views.generic.base.TemplateResponseMixin`](/ja/3.0/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin)
- `django.views.generic.detail.BaseDetailView`
- [`django.views.generic.detail.SingleObjectMixin`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin)
- [`django.views.generic.base.View`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View)

**メソッドのフローチャート**

1. [`setup()`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View.setup)
2. [`dispatch()`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View.dispatch)
3. [`http_method_not_allowed()`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View.http_method_not_allowed)
4. [`get_template_names()`](/ja/3.0/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.get_template_names)
5. [`get_slug_field()`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_slug_field)
6. [`get_queryset()`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_queryset)
7. [`get_object()`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_object)
8. [`get_context_object_name()`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_object_name)
9. [`get_context_data()`](/ja/3.0/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_data)
10. `get()`
11. [`render_to_response()`](/ja/3.0/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.render_to_response)

**Example myapp/views.py**:

```
from django.utils import timezone
from django.views.generic.detail import DetailView

from articles.models import Article

class ArticleDetailView(DetailView):

    model = Article

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context
```

**例 myapp/urls.py**:

```
from django.urls import path

from article.views import ArticleDetailView

urlpatterns = [
    path('<slug:slug>/', ArticleDetailView.as_view(), name='article-detail'),
]
```

**Example myapp/article\_detail.html**:

```html+django
<h1>{{ object.headline }}</h1>
<p>{{ object.content }}</p>
<p>Reporter: {{ object.reporter }}</p>
<p>Published: {{ object.pub_date|date }}</p>
<p>Date: {{ now|date }}</p>
```

## List Views

#### `class django.views.generic.list.ListView`

オブジェクトのリストを表示するページです。

このビューが動作している間、`self.object_list` はビューが操作しているオブジェクト (通常はクエリーセットですが、そうとは限りません) のリストを含みます。

**継承元 (MRO)**

このメソッドは、以下のビューからメソッドと属性を継承しています:

- [`django.views.generic.list.MultipleObjectTemplateResponseMixin`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectTemplateResponseMixin)
- [`django.views.generic.base.TemplateResponseMixin`](/ja/3.0/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin)
- [`django.views.generic.list.BaseListView`](#django.views.generic.list.BaseListView)
- [`django.views.generic.list.MultipleObjectMixin`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin)
- [`django.views.generic.base.View`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View)

**メソッドのフローチャート**

1. [`setup()`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View.setup)
2. [`dispatch()`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View.dispatch)
3. [`http_method_not_allowed()`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View.http_method_not_allowed)
4. [`get_template_names()`](/ja/3.0/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.get_template_names)
5. [`get_queryset()`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.get_queryset)
6. [`get_context_object_name()`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.get_context_object_name)
7. [`get_context_data()`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.get_context_data)
8. `get()`
9. [`render_to_response()`](/ja/3.0/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.render_to_response)

**Example views.py**:

```
from django.utils import timezone
from django.views.generic.list import ListView

from articles.models import Article

class ArticleListView(ListView):

    model = Article
    paginate_by = 100  # if pagination is desired

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context
```

**例 myapp/urls.py**:

```
from django.urls import path

from article.views import ArticleListView

urlpatterns = [
    path('', ArticleListView.as_view(), name='article-list'),
]
```

**例 myapp/article\_list.html**:

```html+django
<h1>Articles</h1>
<ul>
{% for article in object_list %}
    <li>{{ article.pub_date|date }} - {{ article.headline }}</li>
{% empty %}
    <li>No articles yet.</li>
{% endfor %}
</ul>
```

If you're using pagination, you can adapt the [example template from
the pagination docs](/ja/3.0/topics/pagination/#using-paginator-in-view). Change instances of
`contacts` in that example template to `page_obj`.

#### `class django.views.generic.list.BaseListView`

オブジェクトのリストを描画するための基本ビューです。直接使用されるのではなく、 [`django.views.generic.list.ListView`](#django.views.generic.list.ListView) の親クラスやオブジェクトのリストを表す他のビューとして使用されることが目的です。

**継承元 (MRO)**

このメソッドは、以下のビューからメソッドと属性を継承しています:

- [`django.views.generic.list.MultipleObjectMixin`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin)
- [`django.views.generic.base.View`](/ja/3.0/ref/class-based-views/base/#django.views.generic.base.View)

**メソッド**

#### `get(request, *args, **kwargs)`

`object_list` をコンテキストに追加します。[`allow_empty`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.allow_empty) が True の場合、空のリストを描画します。[`allow_empty`](/ja/3.0/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.allow_empty) が False の場合、 404 エラーを投げます。
