Description

« Hide

DBListClass uses a query to populate the displayed selectbox with values. It would be useful to be able populate not only the values, but also the displayed text for each value.

For example, i have a colection of objects in the database, each object having an id and a displayed name. Populating the DBListClass with ids enforces the user to lookup/remember ids, and this should be avoided. Populating it with names negates the role of the id.

There are 2 variants for this:

add a new field in the Meta class, has_labels
detect if the resultset is composed of single values or pairs

Please advise.

Fixed in rev. 1902. When the select returns two columns, the ListProperty.getElementValue and ListProperty.getDisplayedValue return the value, respectively label for the current item. Otherwise, both functions return the same value.
