Retrieve ProxyDeployment by ContractName

[simontianx]

Hi there, coming from using the hardhat-deploy-ethers plugin to retrieve a contract by its name, I found a deployed proxy through hardhat upgrades plugin cannot be retrieved the same way. See this link for how getContract<T>(contractName) works under the hood.

Wondering if proxy deployment could be retreived by contract name in the same way. If this is already possible, how is it achieved? Thanks.

import { HardhatRuntimeEnvironment } from "hardhat/types";
import { DeployFunction } from "hardhat-deploy/types";
import { ethers, upgrades } from "hardhat";
import { Manifest } from '@openzeppelin/upgrades-core';

const func: DeployFunction = async function (hre: HardhatRuntimeEnvironment) {
  const { deployments, getNamedAccounts } = hre;
  const { deploy } = deployments;
  const { deployProxy } = upgrades;
  const { deployer } = await getNamedAccounts();
  const { provider } = hre.network;
  const manifest = await Manifest.forNetwork(provider);
  const get = deployments.getOrNull;

  const Box = await ethers.getContractFactory("Box");
  const box = await deployProxy(Box, [], { kind: "uups" });
  await box.connect(deployer).deployed();

  console.log(await get("Box"));

  const proxies = (await manifest.read()).proxies;
  console.log(proxies);
  console.log(await manifest.getProxyFromAddress(proxies[0].address));
};
export default func;

@simontianx followed this ticket here from the oz forum. the manifest you are referring to does have the proxy addresses, implantation addresses & storage layout which then has contract name. I am look at the files here projectRootFolder/.openzeppelin/chainName-chainId.json. So it should be possible to get proxy address by name by processing info in this file and then reading from the chain to see which proxy has which implementation file.
