Play (Scala) Configuration Map Object - scala

Question

I would like to access the following configuration
customers {
"cust1" {
clientId: "id1"
attrs {
att1: "str1"
att2: "str2"
att3: "str3"
att4: "str4"
}
}
"cust2" {
clientId: "id2"
attrs: {
att1: "faldfjalfj"
att2: "reqwrewrqrq"
}
}
"cust3" {
clientId: "id3"
attrs {
att2: "xvcbzxbv"
}
}
}
as a Map[String, CustomerConfig] where CustomerConfig is
package models
import play.api.ConfigLoader
import com.typesafe.config.Config // I added this import in order to make the documentation snippet compile to the best of my knowledge.
case class CustomerConfig(clientId: String, attrs: Map[String, String])
object CustomerConfig {
implicit val configLoader: ConfigLoader[CustomerConfig] = new ConfigLoader[CustomerConfig] {
def load(rootConfig: Config, path: String): CustomerConfig = {
val config = rootConfig.getConfig(path)
CustomerConfig(
clientId = config.getString("clientId"),
attrs = config.get[Map[String, String]]("attrs").map { case (attr, attrVal) =>
(attr, attrVal)
})
}
}
}
For reference, this is how I am currently attempting to reference it:
val resellerEnvMap = conf.get[Map[String, CustomerConfig]]("customers").map {
case (customer, customerConfig) =>
customer -> customerConfig.attrs.map {
case (attr, attrVal) =>
attr -> new Obj(attrVal, customerConfig.clientId)
}
}
based on custom config loader documentation.
The problem is that config.get[A] does not exist (neither does config.getMap[K, V]) per the what I believe to be the API docs. I would like a way to populate that map from the configuration file. My end goal is to populate anything in the functional vicinity of Map[String, Map[String, (String, String)]] where the first String is the customer name, the 2nd is attribute name, the 3rd is the attribute value, and lastly, the 4th is the client ID.

Play 2.6 uses com.typesafe:config 1.3.2 while the link you posted seems to be from version 2? Here's one way to do it:
object CustomerConfig {
implicit val configLoader: ConfigLoader[CustomerConfig] = new ConfigLoader[CustomerConfig] {
def load(rootConfig: Config, path: String): CustomerConfig = {
val config = rootConfig.getConfig(path)
import scala.collection.JavaConverters._
val attrConfig = config.getConfig("attrs")
CustomerConfig(
clientId = config.getString("clientId"),
attrs = attrConfig.entrySet().asScala.map { entry =>
(entry.getKey, attrConfig.getString(entry.getKey))
}.toMap
)
}
}
}
