You wouldn't generally want to define your DAL connection or crud in your
module -- instead, you would likely want to define them in your models and
then pass them to your module function as arguments.
I think you would do something like:
def manage(request, db, crud, title, table)
and then in your controller function, call:
manage.manage(request=request, db=db, crud=crud, title=T('blog'),
table=db.blog)
An alternative is just to pass in all the globals in one argument via
globals(). To see an example of that approach, check out the __init__
methods of the Auth and Crud classes in /gluon/tools.py.
You should probably also ask yourself whether you really need this function
to be in a module rather than in a controller or model file. If it's only
used in one controller, put it in that controller file. If it's used across
multiple controllers, consider putting it in a model file (all model files
are executed on every request). It's probably not worth moving it to a
module unless you need it across multiple apps or your models are getting
too bloated.
