How to use generateUUID Virtual functions in Confiform

Question

Hi @Alex Medved _ConfiForms_

May I know how to user  generateUUID Virtual functions in Confiform, we just updating our confiform version to 3.4.3 and a bit confusing how to user this function.

Also of course many thanks for this a new virtual function, this function is will help us to generate the token or randomize value.

Yes, when you attempt to use a function on an empty field then it will obviously not work. As the expression evaluation stopes on the empty value.

You need to use the _func or some field that has a value, for example an "id" field (which has a value after submission - you cannot use it in the form view in UI for new records, as the record is still unsaved)

Also I just realize we can call the virtual function method via _func

Awesome !

Previously the function doesn't want to work because my code is not correct when trying to set the uuid value into a field via iftt.

previous code

fieldA = [entry.fieldA.generateUUID] (the previous value of fieldA is empty)

then change the code to

fieldA = [entry.id.generateUUID] (the field id always having value)

we assuming the problem is because we trying to generate the uuid value from empty field.

Thanks Alex for the function, this's really help
