Function
_listDeletedThings
(filter, render) -> The same Type
- filter (optional)
- A QL expression returning YesOrNoType, to try on each deleted Thing
- render (optional)
- A QL expression saying what to return from each deleted Thing
- Produces
- A List of resulting values from the deleting Things
If no filter is given, all deleted Things will be returned.
The filter can be almost anything. For example, this returns all deleted Things that are children of
My Model:
_listDeletedThings(filter = _model -> _is(My Model))
The render parameter will be applied to each deleted Thing, in the context of the history right before
that Thing was deleted. You can return any sort of value here, both text and non-text. For example, this
renders all of the instances of My Model, showing the name and OID of each with "Restore" button to
undelete it:
_listDeletedThings(filter = _model -> _is(My Model), render=""[[Name]] ([[_oid]]) [[_QLButton(label = ""Restore"", noIcon = true, ql = _undeleteThing)]]"") -> _bulleted
If no render parameter is given, the OIDs of the deleted Things will be returned.
