I'm not sure whether it is just me, but I seem to be stumbling on the
Scala compiler exceptions whatever I do. First there was one when
creating specs that I mailed earlier, and now I get compile problems
when I changed Boot-class.
I have changed Boot-class as follows. Idea is to allow different
database based on runlevel and also cleaning up the tables when doing
tests. I have tried to change models to List[KeyedMapper[Any, Any]]
but then I just get different set of exceptions. If I expand models by
hand to schemify and cleanTables, it works just fine. Should I just
send report to scala lang -list or am I doing something wrong?
class Boot {
def database = ("org.apache.derby.jdbc.EmbeddedDriver",
"jdbc:derby:liftdb_"+Props.mode.toString.toLowerCase+";create=true")
def dbVendor = new ConnectionManager {
def newConnection(name: ConnectionIdentifier): Can[Connection] = {
try {
val (driver, databaseString) = database
Class.forName(driver)
Full(DriverManager.getConnection(databaseString))
} catch {
case e : Exception => e.printStackTrace; Empty
}
}
def releaseConnection(conn: Connection) {conn.close}
}
val models = List(User, Game, GameUser, Hull, Ship, StarSystem)
def schemify {
models foreach {
m => Schemifier.schemify(true, Log.infoF _, m)
}
}
def cleanTables {
models foreach {
m => m.bulkDelete_!!()
}
}
def boot {
Log.info("Running boot at runmode "+ Props.mode)
if (!DB.jndiJdbcConnAvailable_?) DB.defineConnectionManager
(DefaultConnectionIdentifier, dbVendor)
Props.mode match {
case Props.RunModes.Development =>
schemify
case Props.RunModes.Test =>
schemify
cleanTables
case _ =>
}
...
I get this kind of stack trace:
