Ian,
Thanks for the quick turnaround. I'm afraid it's still not quite
working! I'll post a brain dump now, then carry on looking at it.
With your first suggestion of adding two lines to my model.py, the app
now starts correctly, but when I issue a request that accesses the
database I get a the same error as before.
With your suggested patch I get a different error on startup:
C:\paj\tsrweb>start-tsrweb.py
Traceback (most recent call last):
File "C:\paj\tsrweb\start-tsrweb.py", line 5, in ?
import turbogears
File "c:\paj\turbogears\turbogears\__init__.py", line 6, in ?
from turbogears.controllers import expose, flash, validate, redirect, \
File "c:\paj\turbogears\turbogears\controllers.py", line 12, in ?
from turbogears import view, database, errorhandling, config
File "c:\paj\turbogears\turbogears\database.py", line 54, in ?
bind_meta_data()
File "c:\paj\turbogears\turbogears\database.py", line 49, in bind_meta_data
get_engine()
File "c:\paj\turbogears\turbogears\database.py", line 39, in get_engine
dburi = alch_args.pop('dburi')
KeyError: 'pop(): dictionary is empty'
BTW, I realise that ActiveMapper is now deprecated, but we need to keep
backwards compatibility for a little while yet.
