There are a couple options. First, you could put those constants
themselves in a module instead of a model file, and then import them into
models, modules, controllers, etc. Alternatively, in your module, you can
do something like:
from gluon import current
def some_function():
decplaces = current.globalenv['DECPLACES'] # This goes inside a
function, not at the top level of the module.
...
current.globalenv is a dictionary of the web2py global environment.
I would probably take the first approach.
