Ошибка при использовании графического генератора на postgres с uuid_generate_v4()

Question

У меня возникла ошибка, когда я использую генератор сглаженного кода в существующей базе данных postgres 9.3, которая использует uuid_generate_v4() для автоматического генерации идентификаторов для таблиц. Я просто начинаю с пятна, и поэтому я не уверен, если это проблема с моим кодом, моей схемой, с самим пятном или если этот сценарий еще поддерживается.

В качестве примера, у меня есть столбцы, которые были созданы с заявлениями, как это:

id uuid NOT NULL DEFAULT uuid_generate_v4() 

Когда я запускаю пятно генератор кода с sbt run, я получаю сообщение об ошибке, перечисленных ниже. Эта ошибка приводит к сбою генератора кода, и поэтому код не генерируется.

Вот подробности моего проекта SBT ...

проекта/build.properties

sbt.version = 0.13.8 

проект/plugins.sbt

logLevel := Level.Warn 

build.sbt

name := "slick_gen_schema_test" 

version := "1.0" 

scalaVersion := "2.11.7" 

libraryDependencies ++= List(
    "org.postgresql" % "postgresql" % "9.3-1103-jdbc4", 
    "com.typesafe.slick" % "slick_2.11" % "3.0.2", 
    "com.typesafe.slick" % "slick-codegen_2.11" % "3.0.2" 
) 

slick <<= slickCodeGenTask 

sourceGenerators in Compile <+= slickCodeGenTask 

lazy val slick = TaskKey[Seq[File]]("gen-tables") 
lazy val slickCodeGenTask = (sourceManaged, dependencyClasspath in Compile, runner in Compile, streams) map { (dir, cp, r, s) => 
    val outputDir = (dir/"main/slick").getPath 
    val username = "postgres" 
    val password = "postgres" 
    val url = "jdbc:postgresql://10.0.11.13:5432/example" 
    val jdbcDriver = "org.postgresql.Driver" 
    val slickDriver = "slick.driver.PostgresDriver" 
    val pkg = "dao" 
    toError(r.run("slick.codegen.SourceCodeGenerator", cp.files, Array(slickDriver, jdbcDriver, url, outputDir, pkg, username, password), s.log)) 
    val fname = outputDir + "/dao/Tables.scala" 
    Seq(file(fname)) 
} 

Что такое правильный способ использовать гладкий генератор кода в этом случае?

Answer 1

Это ошибка Slick, которая была исправлена ​​в Slick master (https://github.com/slick/slick/pull/1472).

Пока не выйдет Slick 3.2, вы можете решить проблему, изменив схему, чтобы не иметь функционального значения по умолчанию.
