How do i find an object with specific property within nested objects

Question

For example, I have a Paths object

var Paths = {
    path1: {
        name: 'method1',
        get: {
            name: 'param1',
            id: 1
        },
        post: {
            name: 'param2',
            id: 2
        }
    },
    path2: {
        name: 'method2',
        get: {
            name: 'param1',
            id: 3
        },
        post: {
            name: 'param2',
            id: 4
        }
    }
};

I want to get the object based on the id.

I tried doing this _.find(Paths, {get:{id:1}}) But here id can also be in post object.

I need some help in solving this problem in lodash .

Answer 1

to find in object use _.pickBy

var res = _.pickBy(Paths, function(path) {
    return path.get.id === 1 || path.post.id === 1;
});

for unknown key

var res = _.pickBy(Paths, function(path) {
    return _.chain(path)
        .values()
        .some(function(val) {
            return _.get(val, 'id') === 1;
        })
        .value();
});

Actually, your code is good as it is looking only inside get , not post . lodash also has matchesProperty iteratee which, in this case, could be done this way:

_.find(Paths, ["get.id", 1]);

Also, you can filter by custom functions:

_.find(Paths, function(o) { return o.get.id == 2 || o.post.id == 2; });
