django user authenticated

	这样安装后，我们就可以在视图(view)的函数中处理user了。在视图中存取users，主要用 request.user ；这个对象表示当前已登录的用户。如果用户还没登录，这就是一个AnonymousUser对象(细节见下)。1

	你可以很容易地通过 is_authenticated() 方法来判断一个用户是否已经登录了：2

	if request.user.is_authenticated():
	# Do something for authenticated users.
	else:
	# Do something for anonymous users.
	使用User对象

django custom template filter

	1.必须存在于一个应用内,并且应用必须包含在INSTALLED_APPS中
	2.必须包含一个templatetags文件夹，和models.py、views.py一个目录级别。其中必须有__init__.py文件

	。
	3.新建的标签或者过滤器必须以module的形式存在于templatetags文件夹中。module文件的名字就是你在

	template中装载的tags。所以不要和其他app中的标签或者过滤器冲突。

	例子：
	文件目录如下：
