ios - FIrebase 3 query to return value that matches child key/value -


i've upgraded ios application use firebase 3 , query working in firebase 2 no longer works in firebase 3.

the old query written follow. 

firebaseuser.queryorderedbychild("displayname").queryequaltovalue(frienddisplayname)       .observesingleeventoftype(.value, withblock: { snapshot in }

where frienddisplayname have been 'someguy1' , have returned object someguy1 part of.

now however, same query returns nothing on firebase 3. feeling because firebase 3 isn't looking inside child objects themselves, it's looking displayname actual child itself. if update query example returns expected.

    database.child("0hftq3cttfwnfvg0dmea1raypow2").queryequaltovalue("someguy1", childkey: "displayname").observesingleeventoftype(.value, withblock: { snapshot in }

but won't work solution me because don't want have parse through child nodes , search through them etc.. way see 1 solution if firebase had 'catch all' specify child like

database.child(*****).etc

where **** can value, doesn't need specified in actual query.

does know how resolve issue? i've attached firebase json layout below.

thanks!

 {       "users" : {         "0hftq3cttfwnfvg0dmea1raypow2" : {           "displayname" : "someguy1",           "pushoptions" : 1,           "pushtoggle" : false         },         "9batnlbnnoxmovk4lhtqfmngjjy1" : {           "displayname" : "someguy2",           "pushoptions" : 0,           "pushtoggle" : true         }       }     }

i found out despite there being no documentation on it, displayname acts keyword - user object provided firebase offers displayname property, unlike other databases, can't use displayname in other nodes or children - can, it's not searchable. in end changing displayname property username solved problems.

hope helps else.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
