如何在Hyperledger Composer的ACL文件中设置规则以验证枚举？

Question

我的模型文件的小子集是 -

participant Employee identified by empID {
  o String empID
  o EmployeeCategory category
}

enum EmployeeCategory{ 
  o Internal 
  o External 
}

asset CompanyAsset identified by assetID{
  o String assetID  
  -->  Employee owner
  o String status 
}

transaction AssignStatus{
--> CompanyAsset assetObject 
}

现在我想在acl文件中定义一条规则，只有当登录的Participant employeeCategory是＆＃39;内部＆＃39;然后允许创建/更新事务AssignStatus

我能够使用empID字段，但不能用于我想要的枚举

使用您的模型（使用我自己的命名空间）我认为这两个ACL规则可以解决您的问题：

   rule InternalsOnly {
description: "Allow Internals to submit AssignStatus txn type"
participant(p): "org.acme.trading.Employee"
operation: ALL
resource(v): "org.acme.trading.AssignStatus"
  condition: ( p.category == "Internal" )
action: ALLOW   
}

   rule PreventTransaction {
description: "prevent others executing transactions"
participant: "org.acme.trading.Employee"
operation: ALL
resource: "org.acme.trading.AssignStatus"
action: DENY
}
