常用的通用视图：- View
- TemplateView
- RedirectView
这个类是通用类的基类，其它类都是继承自这个类，一般不会用到这个类，个人感觉用函数更简单些。 [Python] 纯文本查看 复制代码 # views.py
from django.http import HttpResponse
from django.views.generic import View
class MyView(View):
def get(self, request, *args, **kwargs):
return HttpResponse('Hello, World!')
绑定路由:
[Python] 纯文本查看 复制代码 # urls.py
from django.conf.urls import patterns, url
from myapp.views import MyView
urlpatterns = patterns('',
url(r'^mine/$', MyView.as_view(), name='my-view'),
)
2. django.views.generic.base.TemplateView在 get_context_data() 函数中，可以传一些 额外内容 到 模板 [Python] 纯文本查看 复制代码 # views.py
from django.views.generic.base import TemplateView
from articles.models import Article
class HomePageView(TemplateView):
template_name = "home.html"
def get_context_data(self, **kwargs):
context = super(HomePageView, self).get_context_data(**kwargs)
context['latest_articles'] = Article.objects.all()[:5]
return context
绑定路由
[Python] 纯文本查看 复制代码 # urls.py
from django.conf.urls import patterns, url
from myapp.views import HomePageView
urlpatterns = patterns('',
url(r'^$', HomePageView.as_view(), name='home'),
)
3. django.views.generic.base.RedirectView用来进行跳转, 默认是永久重定向（301），可以直接在urls.py中使用，非常方便： [Python] 纯文本查看 复制代码 from django.conf.urls import patterns, url
from django.views.generic.base import RedirectView
urlpatterns = patterns('',
url(r'^go-to-django/$', RedirectView.as_view(url='http://djangoproject.com'), name='go-to-django'),
url(r'^go-to-ziqiangxuetang/$', RedirectView.as_view(url='http://www.ziqiangxuetang.com',permant=False), name='go-to-zqxt'),
)
