fromCategory/foreachStream how to get the streamId reliably

EventStoreDB
1

Hi

So I have done the following

fromStream(“My-123”

.when(

{

MyEvent: function(state,event)

{

linkTo(event.someProperty,event); //links to a HelloWorld-<> stream

}

}

);

what I was hoping to do is

fromCategory(“HelloWorld”)

.foreachStream()

.when(

{

MyEvent: function(state, event) {

// use event.streamId and expect it to be HelloWorld- not My-123

}

});

Is there a way of getting the current (and always correct) streamId from a projection using fromCategory and foreachStream?

In this case yes I can read from the event again, but that might not always be the case (i assume).

Thanks.

Well in this case My-123 is correct (its where the original event is)

That said I think we can add/check that both streams are there for linkto events
