Imagine a table like:
map = {'company1': 'sqlite://company1.sqlite','company2:
'sqlite://company2.sqlite','company3': 'sqlite://company3.sqlite'}
then you can do:
dburi = map.get(request.args(0))
if not dburi: raise HTTP(404)
db = DAL(dburi)
Now when you do
http://127.0.0.1:8000/app/default/index/company1
The company1 specifies the database.
If you have another app you can do the same but replace
db = DAL(dburi)
with
db = DAL(dburi,
folder=os.path.join(request.folder,'..','otherapp','databases'))
and it will share the database with the otherapp.
