For a bizobj, 'DataSource' is the name of the underlying table it
represents. If you change it, the queries will now try to pull data from that
new name, which is probably not what you want. The 'DataSource' is not an
arbitrary name; it indicates the 'source' of the 'data' for the bizobj.
If you need multiple bizobjs for the same table, you'll have to do a
little coding. First, in the form's createBizobjs() method, you'll need to
store references to these bizobjs. Let's say the table is 'foo', and you want
to create two bizobjs for this
def createBizobjs(self):
conn = self.Application.getConnectionByName("Foo")
self.foo1 = self.Application.biz.FooBizobj(conn)
self.addBizobj(self.foo1)
self.foo2 = self.Application.biz.FooBizobj(conn)
self.addBizobj(self.foo2)
Now you have two instances of the bizobj stored as attributes of the
form. Next, you'll have to override the form's getBizobj() method:
def getBizobj(self, dataSource=None, parentBizobj=None):
if dataSource == 'foo1':
return self.foo1
elif dataSource == 'foo2':
return self.foo2
else:
return super(ThisFormClass, self).getBizobj(
dataSource=dataSource, parentBizobj=parentBizobj)
Now you can set the DataSource property of your controls to either
'foo1' or 'foo2', and they will be bound the the correct bizobj.
