Thanks for developers of web2py programs. I'm not a programmer but a scientist and engineers. I'm often programming if necessary.
At recent, I began to study the web2py system. I start the welcome examples. And I modified only the models of the new welcome applications, and titled "Working" applications. Then, Some Errors Comments were appeared without Models. And I had recovered the orignal. Then the application of "Working" is normally working. I wrote models/db.py as follows: open models/db.py and added some dbs and save and exit Therefore I think this models/db.py is not influenced to controllers and views. But there are some errors in other systems. I am a novice to web2py.
