I have a transaction placeorder which takes list of supplier as input and creates an order.

transaction PlaceOrder 

    {
        o String orderId
        --> Consumer consumer
        o OrderDetails orderDetails
        --> Supplier[] supplier
        --> Commodity commodity
    }

The order is an asset having list of suppliers

asset Order identified by orderId {
    o String orderId
    o String orderName optional
    o OrderState state
    o OrderDetails orderDetails
    --> SupplyOrder[] supplyOrder
    --> Trader owner 
    --> Commodity commodity
    --> Consumer consumer
    --> Supplier[] supplier
    o Rating rating optional
}

This order is created when placeOrder transaction is called and that should create relationship between the list of suppliers.

For a single supplier I was using 

order.supplier = factory.newRelationship(namespace, 'Supplier', placedOrder.supplier.getIdentifier());

but the above code is failing for list of suppliers.

two things may help

  1. Is your transaction actually called 'placedOrder' (in your code) when you wrote "This order is created when placeOrder transaction is called " (just to check, it may well be).

  2. because you've defined an array of relationships to Supplier, the `factory' statement should probably be:

     order.supplier = factory.newRelationship(namespace, 'Supplier', placedOrder.supplier[0].getIdentifier());

  • Yes the transaction is called placeOrder and placedOrder is the variable in which I get the values from the transaction. I was trying to create a relation between array of Supplier in the order with array of Supplier in the transaction. I changed the array of Suppliers in the order to just Supplier and wrote the piece of code you provided in a loop. It worked for me. Thank you for your help. – Vishal Mar 12 '18 at 14:06
