How to pass Object arguments in constructor when using forge create

[sunny0714]

Simple deployment command of a contract with two constructor arguments using forge is as follows

forge create src/Contract.sol:MyToken --constructor-args "My Token" "MT"

But need to pass some objects as constructor arguments to deploy a contract similar to below one

struct DiamondArgs {
    address owner;
    address init;
    bytes initCalldata;
}

contract MyContract {
    constructor(DiamondArgs memory _args) {}
}

So, the deployment command would look like this

forge create src/MyContract.sol:MyContract --constructor-args {owner: "ownerAddress", init: "initAddress", initCalldata: "initCalldata"}

When trying to pass that object, the result looks like this :

forge create --constructor-args [object Object] ...

What's the workaround for this?

This sort of question should be posted in Q&A under discussions. I just transferred!

ChatGPT says:

To pass objects as constructor arguments to a contract using forge, you can encode the object as JSON and pass the JSON string as an argument to the --constructor-args flag. For example, in the case of the DiamondArgs struct from your example, the deployment command would look something like this:

forge create src/MyContract.sol:MyContract --constructor-args '{"owner": "ownerAddress", "init": "initAddress", "initCalldata": "initCalldata"}'

Alternatively, you can also use the --json flag to pass the object as a JSON file. The command would look something like this:

forge create src/MyContract.sol:MyContract --json diamond-args.json

where diamond-args.json is the name of a file that contains the JSON-encoded DiamondArgs object.

In either case, the DiamondArgs object will be passed to the MyContract contract's constructor as a single argument when the contract is deployed.

It looks like you didn't stringify your JSON object

forge create src/MyContract.sol:MyContract --constructor-args '{"owner": "ownerAddress", "init": "initAddress", "initCalldata": "initCalldata"}'

Tried this with simple contract with object as constructor arguments, but no hope
