使用 hardhat-upgrades 在单独的部署文件中获取先前部署的代理合同

Question

我已经像这样使用 hardhat 部署了一个令牌

const { getNamedAccounts, deployments, network } = hre
const { deploy, log, get } = deployments
const { deployer } = await getNamedAccounts()
log("----------------------------------------------------")
log("Deploying GovernanceToken and waiting for confirmations...")

const governanceTokenContractFactory = await ethers.getContractFactory(GOVERNANCE_TOKEN_NAME);
console.log(`Deploying ${GOVERNANCE_TOKEN_NAME}...`);

const deployedProxy = await upgrades.deployProxy(governanceTokenContractFactory, [], {
  initializer: "initialize",
  kind: "uups",
});


await deployedProxy.deployed();
console.log(`${GOVERNANCE_TOKEN_NAME} proxy deployed to: ${deployedProxy.address}`);

const governanceToken = await governanceTokenContractFactory.attach(
    deployedProxy.address
);

在一个单独的脚本中，我正在尝试部署需要治理令牌的调控器。 通常我可以像这样获得部署的令牌：

const governanceToken = await get(GOVERNANCE_TOKEN_NAME)
//const governanceToken = await ethers.getContract(GOVERNANCE_TOKEN_NAME)

当我尝试这样做时出现错误：

错误：没有使用名称 GovernanceToken 部署的合约

我的猜测是，这与我使用@openzeppelin/hardhat-upgrades进行部署有关，并且它没有像在正常部署期间那样注册它：

import { upgrades } from "hardhat"

如何使用 hardhat-upgrades 在单独的部署文件中获取之前部署的代理合约？

所以在部署之后我需要保存工件。

const { getNamedAccounts, deployments, network } = hre
const { deploy, log, get } = deployments
const { deployer } = await getNamedAccounts()
log("----------------------------------------------------")
log("Deploying GovernanceToken and waiting for confirmations...")

const governanceTokenContractFactory = await ethers.getContractFactory(GOVERNANCE_TOKEN_NAME);
console.log(`Deploying ${GOVERNANCE_TOKEN_NAME}...`);

const deployedProxy = await upgrades.deployProxy(governanceTokenContractFactory, [], {
  initializer: "initialize",
  kind: "uups",
});


await deployedProxy.deployed();
console.log(`${GOVERNANCE_TOKEN_NAME} proxy deployed to: ${deployedProxy.address}`);

const governanceToken = await governanceTokenContractFactory.attach(
    deployedProxy.address
);
const artifact = await deployments.getExtendedArtifact(GOVERNANCE_TOKEN_NAME);
const proxyDeployments = {
    address: deployedProxy.address,
    ...artifact
}

await save(GOVERNANCE_TOKEN_NAME, proxyDeployments);
