Update on this -- There was a spelling mistake in the field name, which
accounts for the error.
But even without an error, we are unable to get replace to replace
anything.
Out of curiosity, we tried using the biz object execute method to issue an
update command, and this worked:
dlg = dabo.ui.createForm("Invalidate.cdxml", show=True, parent=self)
if dlg.Accepted:
bizRuns = self.Form.getBizobj("runs")
ThisRun = bizRuns.getFieldVal('run_no')
bizTubes = self.Form.getBizobj("tubes")
bizTubes.execute("update tubes set result = 'Invalid' where RUNfk = %s" %
ThisRun)
bizTubes.saveAll()
dlg.close()
self.Form.requery()
All the results in the child grid change to 'Invalid'. A query in a MySQL
window verify that the change has been made to the database. Any reason not
to use execute to make these sorts of changes?
But replace method changes neither the values in the result column, nor in
the database.
bizRuns = self.Form.getBizobj("runs")
ThisRun = bizRuns.getFieldVal('run_no')
bizTubes = self.Form.getBizobj("tubes")
bizTubes.replace("tubes.result","Invalid", scope="RUNfk==%s" % ThisRun)
bizTubes.saveAll()
In addition, after running this code, the bizobj seems to be messed up. If
I move in the parent grid off the row that had the change (ThisRun), and
then move back, an information "Notice" pops up, saying "cursor closed" and
displaying the sequel that failed to run. After the popup closes, the child
grid continues to display the records for the previous parent record.
I must be doing multiple things wrong.
