# Generic editing ビュー

以下のビューは、このページで説明され、内容を編集するための基礎を提供します:

- [`django.views.generic.edit.FormView`](#django.views.generic.edit.FormView)
- [`django.views.generic.edit.CreateView`](#django.views.generic.edit.CreateView)
- [`django.views.generic.edit.UpdateView`](#django.views.generic.edit.UpdateView)
- [`django.views.generic.edit.DeleteView`](#django.views.generic.edit.DeleteView)

> **See also**
>
> The [messages framework](/ja/4.2/ref/contrib/messages/) contains
> [`SuccessMessageMixin`](/ja/4.2/ref/contrib/messages/#django.contrib.messages.views.SuccessMessageMixin), which
> facilitates presenting messages about successful form submissions.

> **Note**
>
> このページの例のいくつかは、`Author` モデルが下記の通り `myapp/models.py` 内で定義されているものと見なしています。
>
> ```
> from django.db import models
> from django.urls import reverse
>
>
> class Author(models.Model):
>     name = models.CharField(max_length=200)
>
>     def get_absolute_url(self):
>         return reverse("author-detail", kwargs={"pk": self.pk})
> ```

**属性**

#### `form_class`

Inherited from [`BaseDeleteView`](#django.views.generic.edit.BaseDeleteView). The
form class that will be used to confirm the request. By default
[`django.forms.Form`](/ja/4.2/ref/forms/api/#django.forms.Form), resulting in an empty form that is always
valid.

By providing your own `Form` subclass, you can add additional
requirements, such as a confirmation checkbox, for example.

#### `template_name_suffix`

`GET` リクエストに描画された `DeleteView` のページは、`'_confirm_delete'` の `template_name_suffix` を使います。 例えば、この属性をオブジェクト (例えば `Author` モデル) を作成するビューのために `'_check_delete'` に変更すると、 デフォルトの `template_name` は `'myapp/author_check_delete.html'` となります。

```
from django.urls import reverse_lazy
from django.views.generic.edit import DeleteView
from myapp.models import Author

class AuthorDeleteView(DeleteView):
    model = Author
    success_url = reverse_lazy("author-list")
```

**例 myapp/author\_confirm\_delete.html**:

```html+django
<form method="post">{% csrf_token %}
    <p>Are you sure you want to delete "{{ object }}"?</p>
    {{ form }}
    <input type="submit" value="Confirm">
</form>
```

#### `class django.views.generic.edit.BaseDeleteView`

A base view for deleting an object instance. It is not intended to be used
directly, but rather as a parent class of the
[`django.views.generic.edit.DeleteView`](#django.views.generic.edit.DeleteView).
