ios - Working with Realm and result JSON -


i new realm , trying use realm in project. here trying parse json , save using realm. when trying loop through result array error occurs

'attempting modify object outside of write transaction - call beginwritetransaction on rlmrealm instance first'

this json result:

{"data":[{"id":1,"parent_id":0,"name":"jennifermaenle","title":"ms","phone":"","address":"toled, ohio","email":"jlmaenle@aol.com","image":"44381525_2017.jpg","relation_id":5,"created_at":null,"updated_at":"2017-08-10 02:30:05"},{"id":2, "parent_id":1,"name":"khadeeja","title":"","phone":"","address":"","email":"","image":"khadeeja_2017-07-17.jpg","relation_id":2,"created_at":null,"updated_at":"2017-07-17 08:3:12"}]}

i trying parse json , save in realm database. here try:

class person: object {  dynamic var name = "" dynamic var title = "" dynamic var address = ""  }  override func viewdidload() {     super.viewdidload()     self.add()  }  func add(){     guard let data = datafromfile("serverdata") else { return }      let persons = person()      {          if let json = try jsonserialization.jsonobject(with: data) as? [string: anyobject] {              if let data = json["data"] as? [[string:anyobject]]{                  eachitem in data{                     persons.name = eachitem["name"] as! string                     persons.title = eachitem["title"] as! string                     persons.address = eachitem["address"] as! string                      try! realm.write {                         realm.add(persons)                     }                 }              }         }     } catch {          print("error deserializing json: \(error)")     } }

do not modify persons object , add realm again. error see because add persons realm , edit on second iteration in for eachitem in data again. persons added realm in iteration , try give new name outside realm write transaction. that's why see error. it's better create new object every person.

func add(){     guard let data = datafromfile("serverdata") else { return }      {         if let json = try jsonserialization.jsonobject(with: data) as? [string: anyobject] {             if let data = json["data"] as? [[string:anyobject]]{                 eachitem in data{                     let persons = person()                     persons.name = eachitem["name"] as! string                     persons.title = eachitem["title"] as! string                     persons.address = eachitem["address"] as! string                      try! realm.write {                         realm.add(persons)                     }                 }              }         }     } catch {         print("error deserializing json: \(error)")     } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
