Using Include in live list breaks

[srkraut]

Hello i am using query builder and live list to show data

_queryBuilder = QueryBuilder<ParseObject>(ParseObject('post')) ..includeObject(["poster"]) ..orderByDescending('createdAt');

it woks fine at start but when new data is added and the data used from 'poster' pointer can't be shown and throws null exception . i am trying to show user name .

snapshot.loadedData .get('poster') .get('full_name')

I think this problem occurs as LiveList is build on top of LiveQuery and LiveQuery does not
handle included objects (as far as I know).

As a quick work around you could re-fetch the included object manually.

I agree that such a workaround is not ideal and as this feature would come handy in more complex apps, I will have a lock, if implementing an automated process is possible.

Can you pass me an example . How can i refetch the included object inside livelist ?

Or refresh the livelist manually running full query again

Currently i am refreshing whole page , disable the live query and using livelist just for showing list .

Any optimization and code suggestions are welcome.

You could wrap the widget, that uses the poster object inside a FutureBuilder using this future:
snapshot.loadedData .get<ParseObject>('poster') .update()

Using update doesn't work

this works

FutureBuilder( future:snapshot.loadedData.get<ParseObject>('poster').getAll() , builder: (BuildContext context, AsyncSnapshot<ParseResponse> shot) { return shot.hasData ? Text( shot.data.result[0]['full_name'], style: TextStyle( fontSize: 18.0, fontWeight: FontWeight.bold), ) : Text('-'); }, ),

but its kind of slow and when scrolling values goes and comes .

@srkraut
I've implemented a possible solution in dd837d1 and 8d4a4af.

More improvements can be made, but this should fix your including problem.
For further information have a lock at #348.
