The two following generic class-based views are designed to display data. On many projects they are typically the most commonly used views.
DetailView
¶django.views.generic.detail.
DetailView
¶在执行此视图时,self.object
将包含该视图正在操作的对象。
Ancestors (MRO)
该视图从以下视图继承方法和属性:
django.views.generic.detail.SingleObjectTemplateResponseMixin
django.views.generic.base.TemplateResponseMixin
django.views.generic.detail.BaseDetailView
django.views.generic.detail.SingleObjectMixin
django.views.generic.base.View
Method Flowchart
dispatch()
http_method_not_allowed()
get_template_names()
get_slug_field()
get_queryset()
get_object()
get_context_object_name()
get_context_data()
get()
render_to_response()
示例myapp / views.py:
from django.views.generic.detail import DetailView
from django.utils import timezone
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
¶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.

django.views.generic.list.MultipleObjectTemplateResponseMixin
django.views.generic.base.TemplateResponseMixin
django.views.generic.list.BaseListView
django.views.generic.list.MultipleObjectMixin
django.views.generic.base.View
Method Flowchart
dispatch()
http_method_not_allowed()
get_template_names()
get_queryset()
get_context_object_name()
get_context_data()
get()
render_to_response()

class ArticleListView(ListView):
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 ArticleListView

<h1>Articles</h1>
<ul>
