hyperledger-composer - 超级账本作曲家游乐场中的预期资源或概念

问题描述

我在操场超级账本作曲家中有一个错误说“预期的资源或概念” 两个参与者 1. 学校 2. 公司

两项资产 1. 成绩单 2. Transcript_status

一笔交易 updateStatus： • 将学生的成绩单状态从未读更新为不感兴趣或不感兴趣

参与者学校、学生、公司资产成绩单、成绩单_状态交易更新状态

  1. 学校创建参与学校
  2. 公司创建参与公司
  3. 学校创建资产成绩单
  4. 公司创建资产成绩单_状态

工作流程：创建学生资产（成绩单）后，学校可以将记录上传到其网站，企业可以查看第一个资产成绩单。之后，公司可以提交交易 Transcript_status 并标记为已读。然后资产 Transcript_status 将从未读更新为已读。

解决方案

据我了解，我运行您的代码。我已经解决了一些问题。在您的代码中，您可以更新 areadStatus下的 a transcript asset。如果您更新s资产下的单个值，则需要将该资产的对象放入Update函数中。

1.模型文件更改：

transaction UpdateTranscript_status {
  o Boolean readStatus default=false
  --> Transcript transcript
}

2. logic.js 变化：

async function transcriptForUpdated(TforUpdated) { 
  // eslint-disable-line no-unused-vars
    TforUpdated.readStatus = true;

  TforUpdated.transcript.readStatus = TforUpdated.readStatus;


    const registry = await getAssetRegistry('org.school.education.Transcript');
    await registry.update(TforUpdated.transcript);
}

运行此事务后，它将更新 a 下的 readStatus（由true更新false值 ）。Transcript asset

希望它能解决你的问题:)
