Note: this recipe makes web2py has the same nicety of Django managers. If you haven't heard about managers in models, see Model Managers slide and the Managers official documentation.

Web2py doesn't force us to define models as classes. It's a pragmatic approach, but lead us to some lack of organization.

It's what we'll show now.

The secret is  the @make_member_of decorator:

So, just define the make_member_of() function before your table definitions and enjoy your new table methods.
