这是管理员索引视图的作用：

@never_cache
def index(self,request,extra_context=None):
    """ 
    Displays the main admin index page,which lists all of the installed
    apps that have been registered in this site.
    """
    app_dict = {}
    user = request.user
    for model,model_admin in self._registry.items():
        # ...
