Google Firebase Android app receiving wrong db information from DataSnapshot -


i making android app require google firebase, , in app have iterate through datasnapshots couple of times. in 1 specific instance, datasnapshop passing data different directory in database specified to. make reference database, add event listener calls ondatachange method passes datasnapshot through. here:

    nref = mfirebasedatabase.getreference();     nref.addvalueeventlistener(new valueeventlistener() {         @override         public void ondatachange(datasnapshot datasnapshot) {             if (datasnapshot.exists()){                 showdatalobreq(datasnapshot);                 showdata(datasnapshot);             } else {              }         }          @override         public void oncancelled(databaseerror databaseerror) {          }     });

and here methods calls:

public void showdatalobreq(datasnapshot datasnapshot){      for(datasnapshot ds : datasnapshot.child("lobby_requests").getchildren()){         system.out.println("here"+ds.getvalue());         game = ds.child(userid).child("game").getvalue(string.class);         console = ds.child(userid).child("console").getvalue(string.class);         mic = ds.child(userid).child("mic").getvalue(string.class);         players = ds.child(userid).child("players").getvalue(string.class);     }   }  public void showdata(datasnapshot datasnapshot){     arraylist<lobbyinformation> lobbies = new arraylist<>();      iterator<datasnapshot> items = datasnapshot.child("lobbies").getchildren().iterator();     lobbies.clear();     while(items.hasnext()){         lobbyinformation lobby = new lobbyinformation();         datasnapshot item = items.next();         lobby.setgamename(item.child("game").getvalue(string.class));         lobby.setconsole(item.child("console").getvalue(string.class));         lobby.setmic(item.child("mic").getvalue(string.class));         lobby.setnote(item.child("note").getvalue(string.class));         lobby.setplayercounttotal(item.child("players").getvalue(string.class));         lobby.sethost(userid);          if(console.equals(item.child("console").getvalue(string.class)) &&                 players.equals(item.child("players").getvalue(string.class)) &&                 mic.equals(item.child("mic").getvalue(string.class)) &&                 game.equals(item.child("game").getvalue(string.class))){              lobbies.add(lobby);         }      }     arrayadapter adapter = new customlistadapterlobby(this, lobbies);     lobbylistview.setadapter(adapter);  }

in first method calls "showdatalobreq" can see use system.out.println see contents of datasnapshot, , discovered showing contents child of datasnapshot iterate through in second method "showdata". have no idea why considering define correct child in enhanced loop @ beginning of method "showdatalobreq".

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
