Ok, I've gotten my events to work, but now have another newb question
that I can't seem to find the answer to. In the update listener I get
the kwargs sent in to find which columns have been changed. I can
reference them as a dictionary. I want to compare the fields sent in to
see if they've changed and to get the previous value of them, but cannot
find how to reference the specific column using a variable. What I'd
like to do is the following:
def updateListener(currentValues, newValues):
for columnName in newValues:
newValue = newValues[columnName]
currentValue = currentValues[columnName] ----- This is what
doesn't work
# log changes here
The currentValues[columnName] doesn't work. How can I get the old value
of the changed column?
I believe 'currentValues' is the object (SQLObject) to be changed, not
a dictionary. Get the values by calling getattr(currentValues, columnName).
Oleg.
Is there a way in the RowCreatedSignal event to capture the name of the
object (table) that is being inserted into?
