hyperledger-composer playground中的预期资源或概念

Question

我有一个错误说“预期资源或概念”在操场上hyperledger-composer两个参与者1.学校2.公司

两个资产1.成绩单2. Transcript_status

一个事务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Assets Transcript，Transcript_status Transaction updateStatus

1. 学校创建了一所参与学校
2. 公司创建参与公司
3. 学校创建资产记录
4. 公司创建资产transcript_status

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，公司可以查看第一个资产成绩单。之后，公司可以提交事务Transcript_status并标记为已读。然后资产Transcript_status将从未读更新为读。

Answer 1

根据我的理解，我运行你的代码。我解决了一些问题。在您的代码中，您可以在readStatus transcript下更新asset。如果更新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，它将在Transcript asset下更新readStatus（false值更新为true）。

希望它能解决你的问题:)
