HTML editor for Google App Engine

Question

Please review this simple code. When I review it I decide to rewrite so that it doesn't write to a template, but instead directly to output since the whole HTML is fetched from the data layer. I used the tool appengine_admin to get editable HTML for simple html capabilities to an appspot project:

 class Page(db.Model):
 html = db.TextProperty(required=True)
 class AdminPage(appengine_admin.ModelAdmin):
 model = Page
 listFields = (
 'html',
 )
 editFields = (
 'html',
 )
 application = webapp.WSGIApplication([ ('/page/([0-9]+)', PageHandler), ])
 class PageHandler(BaseHandler):
 def get(self, file_id):
 page = Page.get_by_id(long(file_id))
 if not page:
 self.error(404)
 return
 self.render_template(file_id+'.html', {
 'body': page.body,
 })

My 2 to-dos:

1. change variable file_id to page_id
2. change writing to direct output instead of template

Answer 1

 application = webapp.WSGIApplication([ ('/page/([0-9]+)', PageHandler), ])

I'd put the list of urls as a global constant, I think that would make it easier to read.

 class PageHandler(BaseHandler):
 def get(self, file_id):
 page = Page.get_by_id(long(file_id))
 if not page:

If you are checking against None here, I'd use if page is None:

 self.error(404)
 return

I'd use else instead of returning here

self.render_template(file_id+'.html', {
 'body': page.body,
})
