Okay, I looked a bit into how configuration works in TG and it seems
the problem is in the get method of tgconfig.TGConfig. If I check what
dict is used to look up keys (such as "sqlobject.dburi" in my case)
while tg-admin sql create is doing its thing, well, it's always empty,
no wonder it can not find a "Database URI".
In a shell however:
[GCC 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import turbogears
>>> turbogears.util.load_project_config('dev.cfg')
>>> print turbogears.config['global']['sqlobject.dburi']
sqlite:///path_to_a_db_file
So it seems the configuration is okay, the uri is there, only tg-admin
sql create can not find it.
This is quite frustrating actually, because my main motivation for
migrating to TG from my home grown mod_python-based "web framework" is
that with TG things are claimed to be just working and I can
concentrate on the application logic and presentation only, without
worrying about the rest. It seems this is not the case, although I
might be doing something totally stupid, although I did nothing else
then follow the 20 minute wiki tutorial.
Cheers,
Daniel
