javascript - 错误 : Expected a Resource or Concept

Question

当我尝试在 composer-playground 中执行事务时，出现错误“getAssetRegistry 正在返回 null，并且错误消息显示 assetRegistry 未定义”

/*这是我的.cto文件:*/

 namespace org.acme.payrent
  participant Authority identified by authorityId  {
      o String authorityId
  }

participant Tenant identified by tenantEmailId {
  o String tenantEmailId regex =/^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$/
  o String tFirstName
  o Address Address
  o TBankDetails tBank
  o Integer accountNo 
}

participant Owner identified by ownerEmailId {
  o String ownerEmailId regex =/^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$/
  o String name
  o String number regex=/^[0-9]*$/
  o Integer bankaccountno
  o Address propAddress
  --> Tenant tnt
}

participant Bank identified by bankID {
  o String bankID
  o TBankDetails tBank
}

asset Property identified by propAddress {
  o String propAddress

  o String mobileNumber regex=/^[0-9]*$/
  o String firstName
  o String lastName
}

  o String owrName
  o String tntName

}`

/* 链码/logic.js 文件: */ `/** * 订购车辆 * @param {org.acme.payrent.Agreement} 创建协议(protocol)交易 * @交易 */

Answer 1

你的代码有很多问题

• 预期资源或概念的原始问题是后者 - 这没有正确提供给事件
• 您在分配给 property 时使用了错误的对象，因此您的 assetRegistry 更新将不起作用
• 您需要在分配给事件字段时定义概念值 - 请参阅代码
• 已留在 console.logs 中以便您可以看到输出
• 您需要为您的交易提供更多数据(例如，概念地址字段)
• 下面有一个 rentAmount 分配 - 您需要删除 - 它在那里，所以您可以看到 Property Assets 已更新，因为它应该由交易 Agreement
