Truffle migration with contract argument

Question

I have have many examples and in the 2_deploy_contracts.js providing simple arguments like address, string is all good.

However I am trying to deploy this example and it has a MintableToken _token as an argument. How do I provide that in 2_deploy_contracts.js?

Answer 1

You can either deploy setting a variable to the contract instance via await, or neater still, use the .then method of the promise to chain the deployments, giving you access to the instance (and so the address) in the deployment of your second contract.

const contractOne = artifacts.require('ContractOne')
    , contractTwo = artifacts.require('ContractTwo')

module.exports = deployer => 
  deployer.deploy(contractOne)
    .then(contOne => deployer.deploy(contractTwo, contOne.address))

And so here, contractOne would be your mintable token contract.
