You could define some_function in a model file (functions defined in model
files are available in views, though functions defined in controllers are
not), and then you could call it directly in your layout.html view (or you
could call it within a separate sidebar view file, and then include that
sidebar view in layout.html). For example:
{{=some_function()['rows']}}
Another option would be to include a component in your sidebar (see
http://web2py.com/book/default/chapter/13#Components), either with or
without using Ajax. For example:
{{=LOAD(f='some_function', ajax=False)}}
