stop_headsign not available in Index API

[barslett]

Trips may change headsign underway, and this is handled by the field stop_headsign, which seems to be handled well both in the model as well as in the Plan API. However, it seems as the field is left out of the Index API (it's missing in TripTimeShort). This seems to have been addressed in in #438 and #1301, with no indications of this having been solved.

We have run into a problem with this now. Because of new metro line patterns, some routes will change destination underway - and this needs to be reflected in the passenger information services, including departure times from stops.

Is there any known workaround?

The TripTimes class has a headsigns String array field. I don't think there should be any problem returning this information, someone just needs to implement it. There does need to be a fallback from from stop headsign to trip headsign.

This is also on our agenda, so I can take a look at it at least for the GraphQL endpoint (which should fix also the REST API)

Is this resolved now? I see that the transit index API returns TripTimeShort objects to represent the stoptimes within a trip. Each TripTimeShort (one for each stop on the trip) has a headsign field. This headsign field is set using the getHeadsign method on the trip times, which checks for a per-stop headsign and falls back to the headsign for the entire trip if there is no array of per-stop headsigns.

We are still using OTP 0.19 (where this doesn't work) and a workaround in production, but I have now checked the Index API in our test system vith OTP 1.0.0, and there, all headsign attributes are present and have the correct content. I have not checked GraphQL, so @hannesj should comment as well.

I have looked at it now in GraphQL, and it was missing in the definition of stopTimeType. Added it and will make a PR.

Closing, as the issue is solved.
