web2py renders only functions that are not take parameters (it's useful to
have a set of "protected" functions).
However, a "helper" is there for your situation
def something():
id = request.args(0,default=0,cast=int,otherwise='http://error_url')
otherwise by default raises a HTTP(404), if is a string it
redirects(there), if is a callable it gets executed
PS: nothing stops you to have a
def somethingwithid(id=None):
return 'something'
def this_is_the_page():
return somethingwithid(request.args(0))
