Flatten an array of objects to Map

[cvsudheer108]

Hi JSLT Team,
I have this input:
[{
"schema" : "http://schemas.schibsted.io/thing/pulse-simple.json#1.json",
"id" : "1",
"published" : "2017-05-04T09:13:29+02:00",
"type" : "View1",
"environmentId" : "urn:schibsted.com:environment:uuid",
"url" : "http://www.aftenposten.no/"
},
{
"schema" : "http://schemas.schibsted.io/thing/pulse-simple.json#1.json",
"id" : "2",
"published" : "2017-05-04T09:13:29+02:00",
"type" : "View2",
"environmentId" : "urn:schibsted.com:environment:uuid",
"url" : "http://www.aftenposten.no/"
}
]

And I want to get a Map back like this:

{
"1" : {
"schema" : "http://schemas.schibsted.io/thing/pulse-simple.json#1.json",
"id" : "1",
"published" : "2017-05-04T09:13:29+02:00",
"type" : "View1",
"environmentId" : "urn:schibsted.com:environment:uuid",
"url" : "http://www.aftenposten.no/"
},
"2" : {
"schema" : "http://schemas.schibsted.io/thing/pulse-simple.json#1.json",
"id" : "2",
"published" : "2017-05-04T09:13:29+02:00",
"type" : "View2",
"environmentId" : "urn:schibsted.com:environment:uuid",
"url" : "http://www.aftenposten.no/"
}
}

How do I get that done with JSLT??

Thanks!

Which part of this are you having difficulties with?

[cvsudheer108]

I see with JSLT, I can only transform an array of objects to another array of objects with transformation.
For eg:
let supplierTariffDetailsMap = [for(.)
let key = .id
let value = .
{$key : $value}
]

$supplierTariffDetailsMap

But I want to create a look-up map as shown above, so that I can look up using get-key().

[larsga]

Note that the code you wrote there is far better written as:

[for(.)
let key = .id
let value = .
{$key : $value}
]

That's also what the optimizer will turn it into.

But that's just a side issue. As to your actual question, you also have for expressions for objects. So you can write:

{for(.) .id : .}

I recommend trying this out with your input in the playground and then iterating from there.
