ios - Retrieving specific Firebase data that is stored in a childByAutoId() Reference (Swift) -


this problem may difficult explain.

here json generated firebase:

{   "users" : {     "2w1sse5kizarfq5k8ukjp87d8rk2" : {       "plainnote" : {         "-kizyvagzqcztsi1l4qi" : {           "note" : "finally works",           "title" : "whats up"         },         "-kizy_m3fmw0m8mgx4am" : {           "note" : "aye",           "title" : "db"         },         "-kizpaesa7-wscojfhvv" : {           "note" : "this wont work reason",           "title" : "helloo"         }       },       "email" : "jacobsiegel@gmail.com"     },     "xtjy66z8xewteilx6e0moo1jeaz2" : {       "email" : "123@gmail.com"     },     "rfzv1sauf3rtpu7ycqj0vyaogmd2" : {       "plainnote" : {         "-kizpfbfhcepu3e8hpeu" : {           "note" : "now see own data",           "title" : "hello"         }       },       "email" : "whatsup@gmail.com"     }   } }

here how generate each plain note in swift: 

let title = plainnotetitletextfield.text!     let note = bodyofnotetextview.text!     let usersid = firauth.auth()?.currentuser?.uid          if title != "" || note != "" {             let data = [                 "title": title,                 "note": note             ]  self.usersref.child(usersid!).child("plainnote").childbyautoid().setvalue(data)

after this, populate tableview in realtime firebase realtime database:

override func viewdidappear(animated: bool) {     var localnotes = [string]()     var localbody = [string]()     let usersid = firauth.auth()?.currentuser?.uid     usersref.child(usersid!).child("plainnote").observeeventtype(.childadded, withblock: { snapshot in         let title = snapshot.value?.objectforkey("title") as! string         var x = snapshot.value?.objectforkey("note") as! string          if x.characters.count > 20 {             x = x[0...20] + "..."         } else {             x = x + "..."         }          localnotes.insert(title, atindex: 0)         localbody.insert(x, atindex: 0)         self.notes = localnotes         self.notebody = localbody         self.tableview.reloaddata()     }) }

my problem: trying access plainnote references when tableview cell tapped, can pull specific note title , body firebase. not sure how without looking @ database every time, because firebase creates unique reference each time new note created.

(p.s.: if think understand, need more details, don't hesitate ask!) thank you.

not sure if have answer yet, here in case (i had same problem). way understand want obtain unique keys generated each time can access data stored underneath single one. generate string array , use extract value of key @ single index can fed data retrieval code. done so:

usersref.child(usersid!).child("plainnote").observeeventtype(.childadded, withblock: { snapshot in  var idkeys = [string]()  //this hold keys  snap in snapshot.children.allobjects {  let id = snap as! firdatasnapshot  idkeys.append(string(id.key))  }}

now have keys, can select 1 using var selectedkey = idkeys[x].

hope helps

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. :)
