Question: Comparing Distinct Arrays of Objects

[mahirk]

Hello,

I am trying to compare an array of objects to check for a specific set of objects to be present in any of them, but not across all of them, specifically lets take this rule:

const arrayRule = {
        conditions: {
            any: [
                {
                    all: [
                        {
                            fact: 'data',
                            path: '$.[*].equalityTest',
                            operator: 'equal',
                            value: 50,
                        },
                        {
                            fact: 'data',
                            path: '$.[*].anotherTest',
                            operator: 'equal',
                            value: 50,
                        },
                    ],
                },
            ],
        },
        event: {
            type: 'arrayRule',
        },
    };

This is the first iteration of the rule I came up with, it is incorrect, but I wanted to give an idea of what I am aiming for.

Specifically here, we have a rule where I want equalityTest to equal 50 and anotherTest to also equal 50. But I want them to equal those values in the same object, such that: THIS SHOULD RETURN FALSE

 const facts = {
                data: [
                    {
                        anotherIntegerFact: 1,
                        equalityTest: 50,
                    },
                    {
                        anotherIntegerFact: 50,
                        equalityTest: 40,
                    },
                ],
            };

THIS SHOULD RETURN TRUE

 const facts = {
                data: [
                    {
                        anotherIntegerFact: 50,
                        equalityTest: 50,
                    },
                    {
                        anotherIntegerFact: 40,
                        equalityTest: 40,
                    },
                ],
            };

Would love any suggestions or ideas on a way to tackle this. One thought was I could write my own operator and add it to the registry of operators on our end, but before I did so, I wanted to validate that is needed.

Thanks

@CacheControl Tagging you because I am unsure of the policy on issues here, thank you in advance!

We have a similar need. Given an array of objects, I want to return true if and only if one of the objects (evaluated by itself) matches multiple conditions.

We have similar use case, can someone suggest any ideas around it.

Any updates on this? @mahirk @alexthehurst @vindu25

@OmarKhattab I no longer remember what caused us to hit this issue, but this kind of requirement can probably be worked around with custom operators, which we've since learned are pretty easy to implement in JRE. If you provide samples of what kind of data you want to match, I might be able to give suggestions on implementation.
