scala - Persist UUID in PostgreSQL using Play Slick - java.sql.BatchUpdateException -


i've been playing around play , came upon problem while trying save sample data postrgesql.

i'm aware can convert uuid string , save way, can't work uuid.

the error get:

error injecting constructor, java.sql.batchupdateexception: batch entry 0 insert "companies" ("id","name") values (?,'amazon') aborted: error: column "id" of type uuid expression of type bytea

my dependencies:

librarydependencies += "org.postgresql" % "postgresql" % "42.1.4" librarydependencies += "com.typesafe.play" %% "play-slick" % "3.0.1"

company case class:

case class company(id: uuid = uuid.randomuuid, name: string)

slick table definition:

val companies: tablequery[companies] = tablequery[companies]  class companies(tag: tag) extends table[company](tag, "companies") {   override def * : provenshape[company] = (id, name) <> (company.tupled, company.unapply)    def id: rep[uuid] = column[uuid]("id", o.primarykey, o.sqltype("uuid"))   def name: rep[string] = column[string]("name") }

in logs i've noticed uuid gets converted indeed bytes:

[debug] s.j.j.statement - preparing statement: insert "companies" ("id","name")  values (?,?) [debug] s.j.j.parameter - /-------------+-----------\ [debug] s.j.j.parameter - | 1           | 2         | [debug] s.j.j.parameter - | bytes       | string    | [debug] s.j.j.parameter - |-------------+-----------| [debug] s.j.j.parameter - | [b@17c2de51 | amazon    | [debug] s.j.j.parameter - | [b@6a4e93d5 | google    | [debug] s.j.j.parameter - | [b@69f81ed7 | microsoft | [debug] s.j.j.parameter - \-------------+-----------/

i appreciate or hints.

you have import specific profile database system. in case:

import slick.jdbc.postgresprofile.api._

although recommend injecting configuration provider , import api. way code work if configure database management system.

class dao @inject()(@nameddatabase("db_name_from_config") protected val dbconfigprovider: databaseconfigprovider)                       (implicit ec: executioncontext) {   import profile.api._    ... }

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

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() .
