1. Я хочу знать, могу ли я внести изменения в параметр, определенный в отношении.
я хочу создать функцию с названием bookflight, а затем внести изменения в количество мест, если рейс забронирован.это мои cto файлы
namespace org.acme.airline.aircraft
/** Aircraft is an ACME Asset*/
asset Aircraft identified by aircraftId {
o String aircraftId
o Ownership ownershipType default="LEASED"
// Number of seats per class
o Integer firstClassSeats range = [4,]
o Integer businessClassSeats range = [6, 20]
o Integer economyClassSeats range = [30, ]
o String nickName optional
}
enum Ownership {
o LEASED
o OWNED
}
и для полета код
namespace org.acme.airline.flight
import org.acme.airline.aircraft.Aircraft
asset Flight identified by flightId {
// Solution to the exercise - try out the Regular expression at http://regex101.com
// Share your optimized regular expression with others :)
o String flightId regex=/[A-Z][A-Z][0-9][0-9][0-9]-[0-9][0-9]-[0-3][0-9]-[0-9][0-9]/
o String flightNumber
o Route route
o String[] aliasFlightNumber optional
--> Aircraft aircraft optional
}
concept Route {
o String origin regex=/[A-Z][A-Z][A-Z]/
o String destination regex=/[A-Z][A-Z][A-Z]/
o DateTime schedule
}
// Logistics department of ACME creates the flights
transaction CreateFlight {
o String flightNumber
o String origin
o String destination
o DateTime schedule
}
event FlightCreated {
o String flightId
}
// Assigns an aircraft to the flight
// The logistics / validation on availability of aircraft
// Kept outside of the Blockchain
transaction AssignAircraft {
o String flightId
o String aircraftId
}
// Event indicating that aircraft was assigned
event AircraftAssigned {
o String flightId
o String aircraftId
}
Теперь я хочу внести изменения в отношение полета, чтобы внести изменения в него, что мне делать,Я сделал файл javascript. Для доступа внесите в него изменения.
function booktickets(registry){
//array to recored the hold the instances of aircraft resourse
const bnDef = bnUtil.connection.getBusinessNetwork();
const factory = bnDef.getFactory();
let flightResource = factory.newResource(aircraftNamespace,aircraftType,'AE201-05-05-2020');
flightResource.setPropertyValue('flightNumber','AE101');
flightResource.route = factory.newConcept(aircraftNamespace,'Route');
flightResource.route.setPropertyValue('origin', 'DEL');
flightResource.route.setPropertyValue('destination' , 'APH');
flightResource.route.setPropertyValue('schedule' , new Date('2018-10-15T21:44Z'));
flightResource.aircraft = factory.newRelationship('org.acme.airline.aircraft', 'Aircraft', 'CRAFT01');
//.setPropertyValue()
flightResource.aircraft.setPropertyValue('ownershipType','LEASED');
flightResource.aircraft.setPropertyValue('firstClassSeats',10);
flightResource.aircraft.setPropertyValue('businessClassSeats',10);
flightResource.aircraft.setPropertyValue('economyClassSeats',100);
return registry.update(flightResource).then(()=>{
console.log('Successfully created the flight!!!');
bnUtil.disconnect();
}).catch((error)=>{
console.log(error);
bnUtil.disconnect();
});
}
