TheView displays a page, and the page template for the page uses  
render_body to insert a html block for the current page. In that html  
block I would like to display a list of events. The pseudo code would  
look like this:

def render_body(self):
     html = format_body_with_markdown(self.body)
     events = "<div>"
     foreach event in self.getEvents():
         evtents += convert_event_to_html(event)
     events = "</div>"
     return html.replace("PLACEHOLDER", events)

My problem is the convert_event_to_html method, if I want to use a  
page template to layout the events. Hope this makes my problem more
