java - How can I store and load my Sessions as a User on Parse? -
i developing android app existing ios app, using session object store data on parse crucial me.
as creating , uploading sessions parse have no problems.
public static void syncuser() { parseuser.getcurrentuser().fetchinbackground(new getcallback<parseobject>() { @override public void done(parseobject object, parseexception e) { if (e != null) { log.d("", "sync error"); e.printstacktrace(); } if (object != null) { syncsessions(); } } }); } private static void syncsessions() { parsequery<parsesession> query = parsequery.getquery(parsesession.class); query.fromlocaldatastore(); query.findinbackground(new findcallback<parsesession>() { @override public void done(list<parsesession> objects, parseexception e) { (parsesession session : objects) { fetchsession(session, null); } } }); } public static void fetchsession(final parsesession session, final onresultcallback cb) { session.saveinbackground(new savecallback() { @override public void done(parseexception e) { if (e != null) { if (cb != null) cb.onresult(false); e.printstacktrace(); } else { if (cb != null) cb.onresult(true); parserelation<parsesession> relation = parseuser.getcurrentuser().getrelation("sessions"); relation.add(session); syncuser(); } } }); } public static void addnewsession(date date, string link, int successvalue) { final parsesession session = new parsesession(); session.put("date", date); session.put("link", link); session.put("successvalue", successvalue); session.pininbackground(new savecallback() { @override public void done(parseexception e) { if (e != null) e.printstacktrace(); else { fetchsession(session, new parsemanager.onresultcallback() { @override public void onresult(boolean success) { if (success) { try { session.unpin(); } catch (parseexception e) { e.printstacktrace(); } } } }); } } }); } public interface onresultcallback { void onresult(boolean success); } for creating new session parameters , uploading use addnewsession() method, , displays in parse dashboard correctly, have columns fields (date, link, successvalue) , stored default session object.
but when try load them parse client, doesn't work. load them method:
public static void getsessions(final onresultcallback cb) { parserelation<parsesession> relation = parseuser.getcurrentuser().getrelation("sessions"); parsequery<parsesession> query = relation.getquery(); query.setlimit(1000); query.findinbackground(new findcallback<parsesession>() { @override public void done(list<parsesession> objects, parseexception e) { if (e != null) { e.printstacktrace(); if (cb != null) cb.onresult(false); } else { cb.onresult(true); } //if (objects != null) //use sessions } }); } i catch exception:
w/system.err: com.parse.parserequest$parserequestexception: wrong type of relation. expecting: , received: _session w/system.err: @ com.parse.parserequest.newpermanentexception(parserequest.java:270) quite similar code on ios works fine "sessions" relation. mistakes have done?
upd. have noticed exception when have allready send custom created session parse addnewsession() , trying them using getsessions(). maybe creating , sending session problem?
i found sollution. after add newly created session user relations with
parserelation<parsesession> relation = parseuser.getcurrentuser().getrelation("sessions"); relation.add(session); i tried save them fetchinbackground, mistake. changed syncuser() parseuser.getcurrentuser().saveinbackground() , worked.
