[web2py] rendering database contents in layout

[kawate]

hello  everybody,

i like to display database records in sidebar of every page.
i define the function that fetch the records and return as dictionary.
then i put the function in default.py and return the result of the
function every view function, it works fine.
such as,
   def some_function():
       ''fetch database records''
      return rows
  def index():
    rows = some_function()
    return dict(rows=rows)

in layout.html:
  {{for row in rows:}}
 <li>{{=row}}</li>
  {{pass}}

But this approach is awkward. i like to hide sidebar rendering from
main page rendering.
There should be more beautiful approach in web2py.
Is there any ideas?

Thank you in advance.
