How to set up different databases per environment in Play 2.0?

Question

I\'d like my Play app to use different databases for test, local and production (production is Heroku) environments.

In application.conf I have:

You can actually still use the Play 1.0 config value naming method, in Play 2, if you, when you load config values, check if Play.isTest, and then prefix the properties you load with 'test.'. Here's a snipped:

def configPrefix = if (play.api.Play.isTest) "test." else ""

def configStr(path: String) =
  Play.configuration.getString(configPrefix + path) getOrElse
     die(s"Config value missing: $configPrefix$path")

new RelDb(
  server = configStr("pgsql.server"),
  port = configStr("pgsql.port"),
  database = configStr("pgsql.database"),
  user = ...,
  password = ...)

And the related config snippet:

pgsql.server="192.168.0.123"
pgsql.port="5432"
pgsql.database="prod"
...

test.pgsql.server="192.168.0.123"
test.pgsql.port="5432"
test.pgsql.database="test"
...

Now you don't need to remember setting any system properties when you run your e2e test suite, and you won't accidentally connect to the prod database.

I suppose that you can optionally place the test. values in a separate file, which you would then include at the end of the main config file I think.
