I have a selector that looks like this:
export const shipmentsRejectedSelector: (
state: AppStateType,
departmentIds: List<number>,
currentDate: DateTime,
toDate: DateTime
) => List<Shipment> = createImmutableEqualSelector(
shipmentsByDepartmentIdsAndDate,
packageEvents,
(shipments, events) =>
shipments
.valueSeq()
.filter(s => s.get('state') == EventType.REJECTED))
?.toList() || List()
)
Since packageEvents returns all events no matter what shipments it is part of, I would like to return only events that are part of the shipments returned by the shipmentsByDepartmentIdsAndDate selector. How can I pass shipmentIds to a new selector that would fetch only events that have the shipmentIds that I am passing?
Something like this for example:
export const shipmentsRejectedSelector: (
state: AppStateType,
departmentIds: List<number>,
currentDate: DateTime,
toDate: DateTime
) => List<Shipment> = createImmutableEqualSelector(
shipmentsByDepartmentIdsAndDate,
shipments => packageEvents(shipments),
(shipments, events) =>
shipments
.valueSeq()
.filter(s => s.get('state') == EventType.REJECTED))
?.toList() || List()
)
In your code you've not shown how you are using the event object in resultFunc(combiner). So I am guessing you want to add events to the shipments before filtering them.
One way could be to use the packageEvents in combiner:
const shipmentsByDepartmentIdsAndDate = ...;
const shipmentWithPackageEvents = createSelector(shipments, (shipments)=>{//return shipments along with the corresponding events});
const shipmentsRejectedSelector = createSelector(
shipmentsByDepartmentIdsAndDate,
(shipments) =>
shipmentWithPackageEvents(shipments).valueSeq()
.filter(s => s.get('state') == EventType.REJECTED))
?.toList() || List()
)
Or we can directly use shipmentWithPackageEvents:
const shipmentsByDepartmentIdsAndDate = ...;
const shipmentWithPackageEvents = createSelector(shipments, (shipments)=>{//return shipments along with the corresponding events});
const shipmentsRejectedSelector = createSelector(
shipmentWithPackageEvents,
(shipments) =>
shipments.valueSeq()
.filter(s => s.get('state') == EventType.REJECTED))
?.toList() || List()
)
