As an alternative, you might try something like this (not tested):
{{import os}}
{{from gluon.template import render}}
{{for m in app.modules.codes:}}
{{=XML(render(filename=os.path.join(request.folder, m, 'left_navig.html'
),
path=os.path.join(request.folder, 'views'), context=
globals()))}}
{{pass}}
You could also move the code to the controller:
def myaction():
result = XML('\n'.join([
render(filename=os.path.join(request.folder, m, 'left_navig.html'),
path=os.path.join(request.folder, 'views'), context=globals
())
for m in app.modules.codes]))
return dict(result=result)
In the view:
{{=result}}
