更新 PersistentVector 中的条目不工作 NEAR 协议

Question

我正在尝试更新作业对象的状态。我收到“成功”消息 return，但该值未更新。我错过了什么吗？

@nearBindgen
export class Contract {
  private jobs: PersistentVector<Job> = new PersistentVector<Job>('jobs');

......

@mutateState()
  cancelJob(jobTitle: string): string {
    for (let i = 0; i < this.jobs.length; i++) {
      if (this.jobs[i].title == jobTitle) {
          this.jobs[i].status = "Cancelled";
        return "success"
      }
    }
    return "not found";
  }

我是这样称呼它的：

near call apptwo.msaudi.testnet cancelJob '{\"jobTitle\":\"title2\"}' --account-id=msaudi.testnet

获取条目时更新条目是不够的。您还需要更新合同上的存储。可以这么说。

这还不够

this.jobs[i].status = "Cancelled";

您需要将其重新添加到：

if (this.jobs[i].title == jobTitle) {
  const job: Job = this.jobs[i]; // Need an intermediate object in memory
  job.status = "Cancelled";
  this.jobs.replace(i, job); // Update storage with the new job.
  return "success"
}
