Question

我有两个交易 GoodsMovement 和 Payment，Goodsmovement 将跟踪 cargo 的交付，Payment 交易将在 cargo 交付时检查付款。

我正在编写以下代码:

    /**
 * New model file
 */

namespace org.acme.paysystem

enum PaymentStatus{
o PARTIALLY_PAID
o TOTAL_AMOUNT_PAID
o NOT_PAID
}

enum DeliveryStatus{
o DELIVERED
o IN_TRANSIT
}

asset Goods identified by billNo{
  o String billNo
  o Double billAmount
  o DateTime billDate
  o DeliveryStatus deliveryStatus
  o PaymentStatus paymentStatus default = 'NOT_PAID'
}

concept Address{
o String Country optional
o String City optional
o String Street optional
o String Zip optional
}

abstract participant user identified by email{
  o String email
  o String fname
  o String lname
  o Address address
}

participant Retailer extends user {
o String shopNo
o Double amountDue
o Double accountBalance
}

participant Distributor extends user{
o String PAN
o Double bankBalance
}

transaction Payment{
  --> Goods goods
  --> Retailer retailer
  --> Distributor distributor
  o PaymentStatus paymentStatus
}

transaction GoodsMovement {
  --> Goods goods
  o DeliveryStatus deliveryStatus

I haven't mentioned GoodsMovement transaction here since it's working as expected. 

脚本文件如下:

/**
* @param {org.acme.paysystem.Payment} Payment
* @transaction
*/
function Payment(Payment){
        var paymentRecievedFlag = 0;
        var amountRecieved = 0;
                if(GoodsMovement == 'IN_TRANSIT')
                    {
                         console.log("Goods are IN_TRANSIT");
                    }
          else
          {
            if ((Payment.retailer.accountBalance - Payment.goods.billAmount) > 0 ){
               Payment.retailer.accountbalance -= Payment.goods.billAmount;
               Payment.distributor.bankBalance += Payment.goods.billAmount;

              Payment.paymentStatus = 'TOTAL_AMOUNT_PAID';
              //Payment.goods.paymentStatus = 'TOTAL_AMOUNT_PAID';
          }

            else{
                  Payment.retailer.amountDue = Payment.goods.billAmount - Payment.retailer.accountBalance;
                  Payment.distributor.bankBalance += Payment.retailer.accountBalance;
                  Payment.paymentStatus = PARTIALLY_PAID;
            }}


          return getParticipantRegistry('org.acme.paysystem.Distributor')
               .then(function(distributorRegistry){
                  return distributorRegistry.update(Payment.distributer);
          })
               .then(function(){
                  return getParticipantRegistry('org.acme.paysystem.Retailer');
          })
               .then(function(retailerRegistry){
                  return retailerRegistry.update(Payment.retailer);
          })
                 .then(function(){
                       return getAssetRegistry('org.acme.paysystem.Goods');
          })
                 .then(function(goodsRegistry){
                        return goodsRegistry.update(Payment.goods);
          });       
}

我已经正确检查并通过 Internet 进行了搜索，但我无法弄清楚我的代码有什么问题。谢谢，如果有人能帮我解决代码问题

Answer 1

第 x 行应该是:

  if(Payment.goods.deliveryStatus == 'IN_TRANSIT')

第 31 行应该是:

 return distributorRegistry.update(Payment.distributor);

第 18 和 25 行应该是指: Payment.goods.paymentStatus = 'TOTAL_AMOUNT_PAID';

不是 Payment.paymentStatus

第 25 行需要引用: Payment.goods.paymentStatus = 'PARTIALLY_PAID';

然后使用此事务 - 它起作用了:

{
  "$class": "org.acme.paysystem.Payment",
  "goods": "resource:org.acme.paysystem.Goods#1",
  "retailer": "resource:org.acme.paysystem.Retailer#a@b.com",
  "distributor": "resource:org.acme.paysystem.Distributor#a@b.com",
  "paymentStatus": "PARTIALLY_PAID"
}
