  2. def andFinally[E2 <: Effect](a: DBIOAction[_, NoStream, E2]): DBIOAction[R2, NoStream, E with E2]

    Run another action after this action, whether it succeeds or fails, and then return the result of the first action.

    Run another action after this action, whether it succeeds or fails, and then return the result of the first action. If the first action fails, its failure is propagated, whether the second action fails or succeeds. If the first action succeeds, a failure of the second action is propagated.

  3. def andThen[R2, S2 <: NoStream, E2 <: Effect](a: DBIOAction[R2, S2, E2]): DBIOAction[R2, S2, E with E2]

    Run another action after this action, if it completed successfully, and return the result of the second action.

    Run another action after this action, if it completed successfully, and return the result of the second action. If either of the two actions fails, the resulting action also fails.

  4. def as[A](a: => A): DBIOAction[A, NoStream, E]

    Replace a result of a successful execution of this action with the given value.

    Replace a result of a successful execution of this action with the given value. If this action fails, the resulting action also fails.

    A shortcut for .map(_ => a).

  5. val as: IndexedSeq[DBIOAction[R, NoStream, E]]
  6. def asTry: DBIOAction[Try[R2], NoStream, E]

    Convert a successful result v of this action into a successful result Success(v) and a failure t into a successful result Failure(t).

    Convert a successful result v of this action into a successful result Success(v) and a failure t into a successful result Failure(t). This is the most generic combinator that can be used for error recovery. If possible, use andFinally or cleanUp instead, because those combinators, unlike asTry, support streaming.

  8. def cleanUp[E2 <: Effect](f: (Option[Throwable]) => DBIOAction[_, NoStream, E2], keepFailure: Boolean = true)(implicit executor: ExecutionContext): DBIOAction[R2, NoStream, E with E2]

    Run another action after this action, whether it succeeds or fails, in order to clean up or transform an error produced by this action.

    Run another action after this action, whether it succeeds or fails, in order to clean up or transform an error produced by this action. The clean-up action is computed from the failure of this action, wrapped in Some, or None if this action succeeded.

    keepFailure

    If this action returns successfully, the resulting action also returns successfully unless the clean-up action fails. If this action fails and keepFailure is set to true (the default), the resulting action fails with the same error, no matter whether the clean-up action succeeds or fails. If keepFailure is set to false, an error from the clean-up action will override the error from this action.
