django---不使用view，直接从Url转到html

这个在使用公告页时，就很方便。

因为无需要经过数据库，视图。

直接使用文字。

Basic examples¶

Django provides base view classes which will suit a wide range of applications. All views inherit from the View class, which handles linking the view in to the URLs, HTTP method dispatching and other simple features. RedirectView is for a simple HTTP redirect, and TemplateView extends the base class to make it also render a template.

Simple usage in your URLconf¶

The simplest way to use generic views is to create them directly in your URLconf. If you’re only changing a few simple attributes on a class-based view, you can simply pass them into theas_view() method call itself:

from django.urls import path
from django.views.generic import TemplateView

urlpatterns = [
    path('about/', TemplateView.as_view(template_name="about.html")),
]

Any arguments passed to as_view() will override attributes set on the class. In this example, we set template_name on the TemplateView. A similar overriding pattern can be used for the urlattribute on RedirectView.
