Nested response

[kotyara85]

Hello everyone,
I have this flat structure:

{
    "objects": {
        "test:abc": {
            "urn": "test:abc"
        },
        "test2:abc": {
            "urn": "test2:abc",
            "parent": "test:abc"
        },
        "test2:bcd": {
            "urn": "test2:bcd",
            "parent": "test:abc"
        }
    }
}

As you can see some objects are owned by others
Is there a way to build this kind of response in opa based on the data input?

        "test:abc": {
            "urn": "test:abc",
            "objects": {
                "test2:abc": {
                    "urn": "test2:abc",
                    "parent": "test:abc"
                },
                "test2:bcd": {
                    "urn": "test2:bcd",
                    "parent": "test:abc"
                }
            }
        }

Getting just the root objects is not a problem with this func

modules[o] {
	some key
	objs := data.objects[key]
	glob.match(input.type, [":"], objs.urn)
        o := objs
}

Thanks

Hi Konstantin! Sure, something like this, maybe?

package play

import future.keywords

modules[obj] {
    some obj in data.objects
    glob.match(input.type, [":"], obj.urn)
}

transform[mod.urn] = obj {
    some mod in modules
    obj := {
    	"urn": mod.urn,
        "objects": {k: v | v := data.objects[k]; v.parent == mod.urn}
    }
}
