TemplateView and RedirectView in Django 1.3
Category: /blog /djangoTags: django
TemplateView
目的很简单: 给定一个URL和一些简单参数, TemplateView返回一个静态页面. 如果没有其它的CMS, 这是一个快速返回静态页面的方法. 例如: 你有一个”Terms of Service”页面, 里面的内容是固定的. 最好的办法应该是在WWW server一级就返回. 如果非要在Django这一层实现的话, 可以这样做:
in urls.py,
# urls.py
from django.conf.urls.defaults import *
from some_app.viems import TosView
urlpatterns = patterns('',
(r'^tos/', TosViewView.as_view()),
)
How to specify template name
in urls.py
from django.conf.urls.defaults import *
from django.views.generic import TemplateView
urlpatterns = patterns('',
(r'^about/', TemplateView.as_view(template_name="about.html")),
)
in class view definition
# some_app/views.py
from django.views.generic import TemplateView
class AboutView(TemplateView):
template_name = "about.html"
How to pass parameters
in urls.py
(r'^template/simple/(?P<foo>\w+)/$',
TemplateView.as_view(template_name='generic_views/about.html')),
在about.html里就可以得到foo的值. 如果想在view里添加更多的变量,
class CustomTemplateView(generic.TemplateView):
def get_context_data(self, **kwargs):
return {
'params': kwargs,
'key': 'value'
}
(r'^template/custom/(?P<foo>\w+)/$',
views.CustomTemplateView.as_view(
template_name='generic_views/about.html')),
这样在about.html可以得到foo, key, params的值.
RedirectView
RedirectView一般两个作用:
- 用户访问一个URL, 然后被服务器重定向到另一个URL
-
处理完一个POST request之后, 需要返回一个redirect
#simple case from django.views.generic import RedirectView (r'^source_url/$', RedirectView.as_view(url='dest_url')), # with args (r'^source_url/(?P<foo>\w+)/$', RedirectView.as_view( url='dest_url', query_string=True)), In response['Location'], the parameter will be there like dest_url/<foo>. # you can also change the URL content (r'^source_url/200/$', RedirectView.as_view( url='dest_url/%(object_id)d/', object_id=100)),
