so a regular type :)
I have a question about using Play+Macwire+Akka
How can I inject Play's ActorSystem with macwire?
in documentation they says "import play.api.libs.concurrent.Akka"
it is works, but not with Macwire...
Actually it is working now :)
import play.api.Play.current
import play.api.libs.concurrent.Akka
trait ActorsModule {
lazy val actorSystem = Akka.system
}
this module is fine. The problem was here
object Global extends GlobalSettings with Macwire {
val wired = wiredInModule(Application)
override def getControllerInstanceA = wired.lookupSingleOrThrow(controllerClass)
}
I made wired lazy and all goes fine :)
so it was the initialization order
common with lazy vals :)
I can't write like this:
class PostgreDatabase(dbPoolActor: ActorRef)
because I have more than one Actors in my system that I want to inject
class PostgreDatabase(dbPoolActor: ActorRef)
because I have more than one Actors in my system that I want to inject
Looks like I should use tags
I have:
import play.api.Play.current
import play.api.libs.concurrent.Akka
trait ActorsModule {
lazy val actorSystem = Akka.system
lazy val dbPoolActor = actorSystem.actorOf(Props(wire[DBPoolActor])).taggedWith[DBPoolActor]
}
and DB
class PostgreDatabase(dBPoolActor: ActorRef @@ DBPoolActor) extends Database { ...
}
But how my DatabaseModule should looks like???
trait DatabaseModule {
lazy val database: Database = ???
}
doesn't it work using just
%%?
@easel I just updated the scalajs example to newest of everything and I think it works fine with
%%, no dedicated build neeeded, see: https://github.com/adamw/macwire/tree/master/examples/scalajs
Hi guys! I wonder if there is any automatic way to inject multiple dependencies implementing the same interface (extending the same trait) in a form of a List (or Set, or other collection, or even shapeless HList) using macwire? I'm talking about some functionality more or less similar to the multibinding in Guice
Like this:
def strategy1()(implicit staticsContext: StaticsContext, param1: Param1) = wire[Strategy1]
class Strategy1 @Inject() (val service1: Service1, val service2: Service2)(implicit staticsContext: StaticsContext, param1: Param1) { ... }
Or should I separate this into two classes?
hello! I am doing some programming with scala on android and I thought about using macwire. Everything works nicely but I got stuck with injecting class which depends on the other one extending module. Example:
class ChatPresenter(chatContractView: ChatContractView) extends ChatContractPresenter { }
trait ChatModule {
import com.softwaremill.macwire._
lazy val presenter: ChatContractPresenter = wire[ChatPresenter]
}
class ChatFragment extends BaseFragment with ChatModule { pesenter. ..... }So I want to use ChatPresenter in ChatFragment. How can I achieve this ?
ok, I resolved my problem, in case someone will have the same problem, I'm leaving solution here:
trait ChatModule {
import com.softwaremill.macwire._
def presenter(chatContractView: ChatContractView) : ChatContractPresenter = wire[ChatPresenter]
}
class ChatFragment extends BaseFragment
with ChatContractView
with ChatModule {
val chatPresenter = presenter(this)
}
Maybe a strange question, but as Macwire is at compile time, is it possible to DI types?
In the mean time I got it to blow up completely: exception during macro expansion:
