trait CurrentDBAction extends PredicatedDBAction

Defines the DBAction default behaviour
class DBAction extends PredicatedDBAction

DB Action, decoupled from Application

Useful for tests, see TestableDBActionTest.scala
case class DBAttributes(executionContext: ExecutionContext, maybeThreadPool: Option[ThreadPoolExecutor], minConnections: Int, maxConnections: Int, partions: Int, maxQueriesPerRequest: Int) extends Product with Serializable
case class DBSessionRequest[A](dbSession: Session, dbExecutionContext: ExecutionContext, request: Request[A]) extends WrappedRequest[A] with Product with Serializable

Wrapped request with added db-specific information.

See the slick package object for implicit functions to extract this information.
class Database extends PlayDatabase
class DefaultSlickConfig extends SlickConfig

@Singleton()
final class MaybeApplication extends AnyVal

Value class wrapper for optionally supplied implicit Applications.
trait PredicatedDBAction extends AnyRef

trait Profile extends AnyRef

This profile makes it easier to use the cake pattern with Slick

Example

class DAO(override val profile: ExtendedProfile) extends CatComponent with Profile

trait CatComponent { this: Profile => //<- step 1: you must add this "self-type"
  import profile.simple._ //<- step 2: then import the correct Table, ... from the profile

  object Cats extends Table[Cat]("CAT") {
    ...
  }
}

object current {
  val dao = new DAO(DB.driver(play.api.Play.current))
}

object DBAction extends CurrentDBAction

Use the DBAction when you want to use the default settings in your controller.
Use the DBAction when you want to use the default settings in your controller.
```
def index = DBAction{ implicit rs =>
  Ok(MyStuff.list())
}
```
By default it uses the database named by default in the configuration in all modes (Prod, Dev) except in test, where it uses test.
It is possible to define a maximum amount queries per request that can be handled at a given point to avoid overloading the application (user gets the error page instead of seeing a slow app).
The maximum amount of per requests is read from: db.<db-name>.maxQueriesPerRequest
If you need to override the default behavior, create a new object with the DefaultDBAction trait.
```
class AnotherDBAction(myApp: Application, myErrorPage: Result) extends DefaultDBAction {
  override lazy val app = myApp
  override val errorPage = myErrorPage
}
```

object MaybeApplication

Use the MaybeApplication wrapper to avoid multiple overloaded methods with defaults.
