Having issue when adding a common value to every elements in array using Jolt - jolt

Question

I am currently using Jolt to work on this input:
{
"banking_account": {
"accounts": [
{
"accountId": "account1"
},
{
"accountId": "account2",
"nickname": "nickname2"
}
]
},
"account_balance": {
"total_value": {
"currency_code": "USD",
"value": "100.00"
},
"balance_accounts": [
{
"id": "id1"
},
{
"id": "id2"
}
]
}
}
And the expected output is:
{
"Data": {
"Accounts": [
{
"AccountId": "account1",
"Account": {
"Identification": [
"id1",
"id2"
]
},
"Currency": "USD"
},
{
"AccountId": "account2",
"NickName": "nickname2",
"Account": {
"Identification": [
"id1",
"id2"
]
},
"Currency": "USD"
}
]
}
}
And here is my current spec:
[
{
"operation": "shift",
"spec": {
"banking_account": {
"accounts": {
"*": {
"accountId": "Data.Accounts.[&1].AccountId",
"nickname": "Data.Accounts.[&1].NickName"
}
}
},
"account_balance": {
"total_value": {
"currency_code": "Data.Accounts.[&1].Currency"
},
"balance_accounts": {
"*": {
"id": "Data.Accounts.[&1].Account.Identification"
}
}
}
}
}
]
And here is my current output:
{
"Data": {
"Accounts": [
{
"AccountId": "account1",
"Account": {
"Identification": "id1"
}
},
{
"AccountId": "account2",
"NickName": "nickname2",
"Account": {
"Identification": "id2"
}
}
]
}
}
So I am having two questions:
Why is the "Currency" value missing? Even if I added something like
"account_balance": {
"total_value": {
"currency_code": "Data.Accounts.[&1].Currency"
}
}
How to map both two balances accounts to both two accounts? Now it seems like an 1->1 mapping; and I wish to have a 2*2 mapping.
Thanks a lot for your help in advance!

Answer 1

You can use this spec for your solution but point 2 is not covered in this and I have added reason for 2nd:
[
{
"operation": "shift",
"spec": {
"banking_account": {
"accounts": {
"*": {
"accountId": "Data.Accounts.[&1].AccountId",
"nickname": "Data.Accounts.[&1].NickName"
}
}
},
"account_balance": {
"total_value": {
"currency_code": "Data.Currency"
},
"balance_accounts": {
"*": {
"id": "Data.Identification"
}
}
}
}
}, {
"operation": "shift",
"spec": {
"Data": {
"Accounts": {
"*": {
"*": "Data.Accounts.[&1].&",
"#(2,Currency)": {
"USD": {
"#USD": "Data.Accounts.[&2].Currency"
}
}
}
},
"Identification": "Data.Identification"
}
}
}
]
& This will answer your two questions :
1 : Why is the "Currency" value missing? Even if I added something like
So you are basically populating a single field element as multiple fields in an array with [&1] which is not possible that's why its not populating.
To do such a case you need to create new elements that will be populating in the Accounts array if you see my spec I am adding a new Current field in every object of Accounts array ->
"Accounts": {
"*": {
"*": "Data.Accounts.[&1].&",
"#(2,Currency)": { //Going 2 levels up to get to currency
"USD": { //If else to check Currency is USD
"#USD": "Data.Accounts.[&2].Currency" //Adding the field in each object of Accounts array.
}
}
}
How to map both two balances accounts to both two accounts? Now it seems like an 1->1 mapping; and I wish to have a 2*2 mapping.
--> This can be achieved in the similar way I have done for 1 but this will again require alot of hardcoding in JOlt.
So my suggestion is to keep both Currency and Identification outside Accounts Array in Data as single object.
