Play Frameworkアプリを使用してherokuにpostgresデータベースをセットアップしようとしていますが、DATABASE_URLに関してエラーが発生し続けます。

 !     Failed to build app with sbt
 !     Heroku push rejected, failed to compile Play 2.0 - java app
       error: failed to push some refs to 'git@heroku.com.git'

次のコマンドを使用して、DATABASE_URLを環境変数として設定しました。

echo "export DATABASE_URL=postgres://postgres:1234@localhost/Play">>.bash_profile
 . .bash_profile

別のURLも設定しようとしましたが、コマンドheroku configを使用して、非常に長いpostgres URLであることがわかりましたが、うまく機能せず、毎回同じ例外が発生しました。

これが私のapplication.confファイルに追加したものです

%prod.db=${DATABASE_URL}

依存

val appDependencies = Seq(
   "postgresql" % "postgresql" % "9.1-901.jdbc4"
)

だから今私は私のについて混乱していDATABASE_URLます。herokuが適切な値で置き換えることができない理由。herokuはどこで適切なURLを探していますか？私のapplication.confファイルまたは私のシステムのbashプロファイルに設定された環境変数に？

どんな助けでも本当にありがたいです。

ありがとう

Play1とPlay2の規則をいくつか混ぜているようです。Play 2を使用しているようです。Play2では、これを設定する最も簡単な方法は、で使用せずDATABASE_URL、代わりに：application.confのデータベース構成をオーバーライドすることです。Procfile

web: target/start -Dhttp.port=$PORT -DapplyEvolutions.default=true -Ddb.default.driver=org.postgresql.Driver -Ddb.default.url=$DATABASE_URL

より詳細なウォークスルーについては、私のPlay2チュートリアルを参照してください。

Herokuでplay2.4、Slick 3.0.3、postgresを使用すると、SQL進化スクリプトを実行する次のセットアップが機能します。

build.sbt内：

name := """app-name"""

そして、libraryDependencies ++ = Seq（

"com.typesafe.play" %% "play-slick" % "1.0.1",
"com.typesafe.play" %% "play-slick-evolutions" % "1.0.1",
"com.typesafe.slick" %% "slick" % "3.0.3",
"org.postgresql" % "postgresql" % "9.4-1201-jdbc41",
"org.slf4j" % "slf4j-nop" % "1.6.4",

application.conf内：

slick.dbs.default.driver ="slick.driver.PostgresDriver$"
slick.dbs.default.db.dataSourceClass = "slick.jdbc.DatabaseUrlDataSource"
slick.dbs.default.db.properties.driver = "org.postgresql.Driver"

およびProcfile：

web: target/universal/stage/bin/app-name -Dhttp.port=${PORT} -Dplay.evolutions.db.default.autoApply=true

乾杯
