Hi
I am developing a data-driven application with TG
I needed to distribute the SQLObject model classes into multiple
files.
I have done it as described below
*)Created a 'models' directory
*)Within that created two model files eg: a.py and b.py
*)Created an __init__.py file within the models directory with
contents
from turbogears.database import PackageHub
__connection__ = hub = PackageHub('projectname')
from projectname.models.a import *
from projectname.models.b import *
I could run the application without any problems.
But, when I added values into a SingleSelectField widget, the problems
began to arise
*)I created a form widget with a SingleSelectField as shown below:
class FormFields(widgets.WidgetsList):
txnType=categories =
widgets.SingleSelectField(options=getValuesFromA())
Here getValuesFromA() is a callable which returns a list of tuples
required for the SingleSelectField as shown below:
def getValuesFromA():
vals = [(A.field1, A.field2)
for item in A.select()]
return vals
Here 'A' is a model class in a.py
When trying to run the application, the following error occurs.
KeyError: 'No database configuration found!'
Anyone have any idea to help me?
I really got stuck...
Thanks in advance
Raj
