I normally use #in models/0.py from gluon.storage import Storage settings=Storage() settings.development=True settings.email_sender='m...@example.com' ...
Anyway, this does not address Iceberg's problem of packing some config files and not others. I am not convinced this scenario should be handled at the web2py level. This is better handled using .hgignore and mercurial or other version control system. I am thinking anyway, to allow a flag when packaging that does not package the database/ folder. So in principle one could create function that updates parameters from a DAL('sqlite://settings.db') On Jun 4, 1:10 am, Iceberg <iceb...@21cn.com> wrote: > IMHO, flask and my lightweight proposal try to solve same problem. > Both can load configuration for sure.
