I think this may be more a python question than a web2py question: With python, you want to read up on decorators. For example: @auth.requires_login() def mycontroller: ..... can be either before, around, or after (although you can certainly do before / after in other, simpler ways). For example: @before_decorator() @around_decorator() def myfunction: .... For background, you could start with: http://docs.python.org/reference/compound_stmts.html#function http://www.artima.com/weblogs/viewpost.jsp?thread=240808 http://www.artima.com/weblogs/viewpost.jsp?thread=240845 > > Many thanks in advance.
