[web2py] Problem with using a method from a module

[Sathvik Ponangi]

Hi,

 I'm using Web2py (1.99.2_Stable) on GAE (1.5.5). 

I have the following class in a module named commons.py:

> class FileSystem():
>
>     def get_file(self, bash):
>         return db(db.files.bash==bash).select().first()
>
> I'm trying to invoke this method from my controller as:

> import commons

commons.FileSystem().get_file("Testing").split(",") 

 
But I get a ticket with the following error:

> AttributeError: FileSystem instance has no attribute 'get_file' 


How do I fix this?

With Regards,
Sathvik
