I would do something like this: when the form comes up, have it show a
modal dialog with fields for the username/password. When they click 'OK', take
the values entered and do your validation. If it isn't valid, alert them and
give the option to re-try. If it is valid, then use the info to query for the
relevant records. Something like this (in the form):
def login(self):
class UserPassDialog(dabo.ui.dStandardButtonDialog):
def afterInit(self):
self.txtUsername = dabo.ui.dTextBox(self)
self.txtPW = dabo.ui.dTextBox(self, PasswordEntry=True)
# Code to create the labels, sizer, etc.
...
dlg = UserPassDialog(self, OK=True, Cancel=True)
dlg.show()
if dlg.Accepted:
# User didn't cancel
user = dlg.txtUsername.Value
pw = dlg.txtPW.Value
biz = self.getBizobj("timeclock") # or whatever your bizobj is
# The next method is whatever you need to validate credentials
if not biz.checkLogin(user, pw):
dabo.ui.stop("Invalid username and/or password")
return
# Set the params for the bizobj
biz.setParams(user)
# I'm assuming that your bizobj is set to query based on username...
self.requery()
Hope that gets you started...
