I am trying to convert the mini chat flask application to web2py.
link: https://github.com/sdiehl/minichat
(1) in the flask code, I can access rooms. and users.
%flask output.
users
{u'test': <__main__.User object at 0x0000000003A7F198>}
When I do a conversion in web2py, I can't access the class variables users.
or room. I needed to redefine rooms in main in the default.py (action).
How do I access the class variable or make them global?
Here is my web2py conversion.
