Django2.0手册:Generic display views

The two following generic class-based views are designed to display data. On
many projects they are typically the most commonly used views.

DetailView¶

class django.views.generic.detail.DetailView

While this view is executing, self.object will contain the object that
the view is operating upon.

Ancestors (MRO)

This view inherits methods and attributes from the following views:

Method Flowchart

  1. dispatch()
  2. http_method_not_allowed()
  3. get_template_names()
  4. get_slug_field()
  5. get_queryset()
  6. get_object()
  7. get_context_object_name()
  8. get_context_data()
  9. get()
  10. 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

Example 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:

<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>

ListView¶

class django.views.generic.list.ListView

A page representing a list of objects.

While this view is executing, self.object_list will contain the list of
objects (usually, but not necessarily a queryset) that the view is
operating upon.

Ancestors (MRO)

This view inherits methods and attributes from the following views:

Method Flowchart

  1. dispatch()
  2. http_method_not_allowed()
  3. get_template_names()
  4. get_queryset()
  5. get_context_object_name()
  6. get_context_data()
  7. get()
  8. 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

Example myapp/urls.py:

from django.urls import path

from article.views import ArticleListView

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

Example myapp/article_list.html:

<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
. Change instances of
contacts in that example template to page_obj.

class django.views.generic.list.BaseListView

A base view for displaying a list of objects. It is not intended to be used
directly, but rather as a parent class of the
django.views.generic.list.ListView or other views representing
lists of objects.

Ancestors (MRO)

This view inherits methods and attributes from the following views:

Methods

get(request, *args, **kwargs)

Adds object_list to the context. If
allow_empty
is True then display an empty list. If
allow_empty is
False then raise a 404 error.
