In this post<https://groups.google.com/forum/#!topic/web2py/dmN54cpMuXo%5B1-25%5D> Massimo says:
"One should not define classes in Models and Controllers. I have issued that warning already to our users..." On the other hand, in this post<https://groups.google.com/d/msg/web2py/Q1sf7DA5BL4/L4pkg-GMuzUJ> and again here <https://groups.google.com/d/msg/web2py/j-_P7nkn_OY/e1TJGksh3XAJ> Anthony says: "You can define classes in models" So I'm looking for some clarification. I can't seem to find anything on this in docs. Can someone point me to where this is discussed in the book, or explain further? Is the rule: classes may *only* be defined in *modules*, or is it more complicated than that? --
