• Distribution
• Retail

foodsupplychaindemo's Issues

Possible error in consume func

The consume function should make changes to asset registry of steak and should update (AssetToConsume) not resturant
`

• @param {org.supplychain.food.model.Consume} param - model instance

• @transaction
  */
  async function ConsumeFunction(param) {
  let assetToConsume = param.liveAsset;
  let restaurant = param.atRestaurant;
  let factory = await getFactory();

  assetToConsume.assetStatus = "CONSUMED";

  const restaurantReg = await getAssetRegistry(namespace + '.LiveAsset');
  await restaurantReg.update(restaurant);

  // emitting Sold event

  let consumedEvent = factory.newEvent('org.supplychain.green.model', 'AssetConsumed');
  consumedEvent.liveAsset = assetToConsume;
  consumedEvent.endGHG = assetToConsume.aggregatedGHG;
  await emit(consumedEvent);
  }
