# Generiska displayvyer

De två följande generiska klassbaserade vyerna är utformade för att visa data. I många projekt är de vanligtvis de mest använda vyerna.

## `DetailView`

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

När denna vy körs kommer `self.object` att innehålla det objekt som vyn körs på.

**Ancestors (MRO)**

Denna vy ärver metoder och attribut från följande vyer:

- [`django.views.generic.detail.SingleObjectTemplateResponseMixin`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectTemplateResponseMixin)
- [`django.views.generic.base.TemplateResponseMixin`](/sv/6.1/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin)
- [`django.views.generic.detail.BaseDetailView`](#django.views.generic.detail.BaseDetailView)
- [`django.views.generic.detail.SingleObjectMixin`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin)
- [`django.views.generic.base.View`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View)

**Flödesschema för metod**

1. [`setup()`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View.setup)
2. [`dispatch()`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View.dispatch)
3. [`http_method_not_allowed()`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View.http_method_not_allowed)
4. [`get_template_names()`](/sv/6.1/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.get_template_names)
5. [`get_slug_field()`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_slug_field)
6. [`get_queryset()`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_queryset)
7. [`get_object()`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_object)
8. [`get_context_object_name()`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_object_name)
9. [`get_context_data()`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_data)
10. [`get()`](#django.views.generic.detail.BaseDetailView.get)
11. [`render_to_response()`](/sv/6.1/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.render_to_response)

**Exempel 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
```

**Exempel myapp/urls.py**:

```
from django.urls import path

from article.views import ArticleDetailView

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

**Exempel 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>
```

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

En basvy för att visa ett enda objekt. Den är inte avsedd att användas direkt, utan snarare som en överordnad klass till [`django.views.generic.detail.DetailView`](#django.views.generic.detail.DetailView) eller andra vyer som representerar detaljer om ett enda objekt.

**Ancestors (MRO)**

Denna vy ärver metoder och attribut från följande vyer:

- [`django.views.generic.detail.SingleObjectMixin`](/sv/6.1/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin)
- [`django.views.generic.base.View`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View)

**Metoder**

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

Lägger till `object` i kontexten.

## `ListView`

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

En sida som representerar en lista med objekt.

När den här vyn körs kommer `self.object_list` att innehålla listan över objekt (vanligtvis, men inte nödvändigtvis en queryset) som vyn arbetar med.

**Ancestors (MRO)**

Denna vy ärver metoder och attribut från följande vyer:

- [`django.views.generic.list.MultipleObjectTemplateResponseMixin`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectTemplateResponseMixin)
- [`django.views.generic.base.TemplateResponseMixin`](/sv/6.1/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`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin)
- [`django.views.generic.base.View`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View)

**Flödesschema för metod**

1. [`setup()`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View.setup)
2. [`dispatch()`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View.dispatch)
3. [`http_method_not_allowed()`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View.http_method_not_allowed)
4. [`get_template_names()`](/sv/6.1/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.get_template_names)
5. [`get_queryset()`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.get_queryset)
6. [`get_context_object_name()`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.get_context_object_name)
7. [`get_context_data()`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.get_context_data)
8. [`get()`](#django.views.generic.list.BaseListView.get)
9. [`render_to_response()`](/sv/6.1/ref/class-based-views/mixins-simple/#django.views.generic.base.TemplateResponseMixin.render_to_response)

**Exempel på 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
```

**Exempel myapp/urls.py**:

```
from django.urls import path

from article.views import ArticleListView

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

**Exempel 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>
```

Om du använder paginering kan du anpassa [exempelmallen från pagineringsdokumenten](/sv/6.1/topics/pagination/#paginating-a-list-view).

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

En basvy för att visa en lista med objekt. Den är inte avsedd att användas direkt, utan snarare som en överordnad klass till [`django.views.generic.list.ListView`](#django.views.generic.list.ListView) eller andra vyer som representerar listor med objekt.

**Ancestors (MRO)**

Denna vy ärver metoder och attribut från följande vyer:

- [`django.views.generic.list.MultipleObjectMixin`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin)
- [`django.views.generic.base.View`](/sv/6.1/ref/class-based-views/base/#django.views.generic.base.View)

**Metoder**

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

Lägger till `object_list` till kontexten. Om [`allow_empty`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.allow_empty) är True så visas en tom lista. Om [`allow_empty`](/sv/6.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.allow_empty) är False så uppstår ett 404-fel.
