Init-script in canton

Questions
1

Hello,

I am trying to translate the below init-script we have into init.canton and have hard time doing so. Appreciate any help i could get!

daml 1.2
module Setup where

import Daml.Script

import Role.Operator

data Parties = Parties with
  operator  : Party

setup : Script ()
setup = do
  operator <-  allocatePartyWithHint "Operator"  $ PartyIdHint with partyIdHint = "Operator"
  opRole <- submit operator $ createCmd OperatorRole with operator

  pure ()

I have gotten this far

import better.files._


val operator = participant1.parties.enable("Operator")
val operatorAssignment = Set(operator -> participant1)

// upload dar file to participants
val darPath = Option(System.getProperty("dar-path")).getOrElse("/.daml/dist/participant-${DAR_VERSION}.dar")
darPath.exists || sys.error(s"cannot find the dar file ${darPath}")
participants.all.dars.upload(darPath)

Is there a way we can ask canton to pick it like we do in daml.yaml, for example: init-script:Setup:setup

Does this help?

Hi @stefanobaghino-da ,

Thanks for your response. This works in a sandbox environment, i’m afraid it’s bit too much for production/prod replica environments as we’ll end up running the daml script command manually. I was able to figure out some stuff in the bootstrap script and it is working, but i’m not sure if it is right or not. Below is the script.

import better.files._


val operator = participant1.parties.enable("Operator")
val operatorAssignment = Set(operator -> participant1)

// upload dar file to participants
val darPath = Option(System.getProperty("dar-path")).getOrElse("/.daml/dist/participant-${DAR_VERSION}.dar")
darPath.exists || sys.error(s"cannot find the dar file ${darPath}")
participants.all.dars.upload(darPath)

participant1.domains.connect_local(mydomain)
val operatorRolePackageId = participant1.packages.find("Role.Operator").head.packageId
val createRoleCommand = ledger_api_utils.create(operatorRolePackageId, "Role.Operator", "OperatorRole", Map("operator" -> participant1.parties.find("Operator")))
participant1.ledger_api.commands.submit(Seq(participant1.parties.find("Operator")), Seq(createRoleCommand))
