Dabo folks:
I'm working on the HoursForm part of the "Step by Step" application tutorial.
I've put together the data entry fields, and have entered in the biz obj code
and the code in the afterInit method on the form. I'm getting the error
<<AttributeError: 'NoneType' object has no attribute 'getBizobj'>>
I don't fully understand (on my third day with Dabo) what's going on with the
bizobj stuff.
->I'm using the standard directory structure (created by quickstart)
->I've got "HoursBizobj.py" located in the biz directory
->the HoursBizobj has the code suggested in tutorial:?
??? def getClients(self):
??????? """Return a 2-tuple of lists of the client names and their keys."""
??????? crs = self.getTempCursor()
??????? crs.execute("select pkid, clientname from clients order by clientname")
??????? ds = crs.getDataSet()
??????? # Create the lists
??????? names = [rec["clientname"] for rec in ds]
??????? keys = [rec["pkid"] for rec in ds]
??????? # Add the entry for an undefined (new) client
??????? names.insert(0, "-Please Select a Client-")
??????? keys.insert(0, 0)
??????? return (names, keys)
??? def validateRecord(self):
??????? ret = ""
??????? # Make sure that the user selected a valid client
??????? if self.Record.clientfk == 0:
??????????? ret = "You must select a valid client"
??????? return ret
-> the afterInit method has the code suggested in the tutorial:
def afterInit(self):
??biz = self.Form.getBizobj("hours")???
??names, pks = biz.getClients()???
??self.Choices = names???
??self.Keys = pks???
??self.ValueMode = "Key"
??? I don't understand why we pass "hours" to the getBizobj function -- the the
bizobj file located in the biz directory is called HoursBizobj.py. I get same
error when I change "hours" to "HoursBizobj" though. How can
self.Form.getBizobj find the HoursBizobj.py code based on the parameter "hours"
???
Thanks for your help, and here's the full "trace back"
