Hello Ed
Platform: GTK
Python Version: 2.4.5 on sco_sv5
Dabo Version: Version 0.8.4; Revision ~4111
UI Version: 2.8.7.1 on wxGTK (gtk2)
-------------------------------------------------------
#1
If I let the ClassDesigner create the Business object for me and then I
edit that, it works. It is when I am trying to instantiate a Biz object
from the biz directory that I have this trouble. I am just trying to
follow the tutorial where it does it separately from the form. This is
the Clients Form.
I am running it with main.py as instructed in the tutorial from the app
main directory. I'm sure it is a naming or import issue being done
wrong. I am not a Python guru, just a hacker.
#2
On the next form of the tutorial, the Hours Form, I have having trouble
understanding how to get a combo box populated with lookup data from the
client database. How do I get the Choices and Keys values into the
combo box. The getClients sub:
def getClients(self):
crs = self.getTempCursor()
crs.execute("select pkid, clientname from public.clients order by
clientname")
ds = crs.getDataSet()
names = [rec["clientname"] for rec in ds]
keys = [rec["pkid"] for rec in ds]
return (names, keys)
Is this tied to the Form object or the ComboBox object.
I have everything else working on this form. Again I put the BizObjects
in with the Class Designer and had no trouble. Following the tutorial, I
could never get it to work. Just starting from scratch and only using
the class designer gave me no trouble.
Thanks for your understanding and help
