How to setup rule in ACL file of Hyperledger Composer to validate against enum

Question

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 
}

Given above is a section of my module file. Now I want to define a rule in the acl file such that only if the logged in Participant employeeCategory is 'Internal' then allow to create/update the transaction AssignStatus

I was able to do it with the empID field but not for the enum which is what i want.

Answer 1

Use these two ACL rules:

   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
}

This should solve your problem.
