How do you pass constructor args when using hardhat-deploy?

[sv250349]

In the following deploy script the constructor args are hardcoded, but that is not dynamic. I need to supply the constructor args from outside the script. There are a number of similar question but non was answered. (https://ethereum.stackexchange.com/questions/112004/how-do-you-deploy-a-smart-contracts-constructor-arguments-with-hardhat)

Could someone please help me with this?

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    const args = ["Ford", "Figo", "Blue", 2010, true, ethers.utils.parseEther("0.002")]
    const carAuction = await deploy("CarAuction", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockChainConfirmations || 1,
    })

    if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        await verify(carAuction.address, args)
    }

What do you mean by "dynamic"?

The smart contract deployment itself is indeed correct,

const carAuction = await deploy("CarAuction", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockChainConfirmations || 1,
    })

is the problem with you wanting a modified args to some conditional for the contract deployment?

Hi, so I want to pass other args to the contract - creating a different contract (auction)

This is confusing.

Same args—different deployment, different args—same deployment, or a different args—different deployment?

You are looking for this I think

It seems like you want to create different contracts for each individual car but why? you can simply create struct for Cars and add as many cars you want for auction through a single contract.

Thanks you for your input and suggestion, that makes sense.
