Hi List, Anyone know how to update a field that has a global variable set as the default value when records are edited (geometry and/or attributes)?
We have a QGIS project with a PostGIS layer loaded and configured with look-ups and relations so the users can update all the relevant fields. There are also "created_by" and "updated_by" fields. These are updated by a trigger in the database with the "current_user" database variable. This works fine if you are the current user that added the layer to the project - the trigger works perfectly. If you give the project to someone else and they create and edit features in the layer the fields are still updated with your name as you are the person who added the layer to the project. Not what we want. QGIS has global variables and there are some new ones - user_account_name and user_full_name that can be set as default values for the fields. When a new feature is created the field is populated with the correct name. Which is what we want. However, when we update an existing record we'd like the "updated_by" field to be updated with the current "user_account_name". Like a trigger in the database would do on update. Then we would have a better idea of the history of the feature.
