Array Length Does Not Work

I get this problem occasionally and I cannot for the life of me figure why !!!

let properties = cs.record(null).schema(cs.ref(‘obj_partner’)).properties;
cs.log(properties);
cs.log(properties.length);

Array outputs to the log as I would expect - I cannot output its length

Thoughts ?

I’ve even tried this off the back of an actual record (partner object in this case) and I get the same result.

I’m guessing what’s being returned is actually an object and NOT an array … which is annoying :joy:

Yep thats exactly it.

For the moment I can work with …

function convertToArray(obj) {
var result = Object.keys(obj).map((key) => [key, obj[key]]);
return result;
}

Yes that’s the correct conclusion. record.schema() return an object, and each of it’s properties are also objects because they are indexed by their identifiers. In the case of properties, it is key value pairs using the property ID => name.

The confusion is probably caused when you log that out and see something like…

...
[properties] => Array
        (
            [PRO0000113EFCAE9] => Forename
            [PRO0000114EFCAE9] => Surname
            [PRO0000001EFCAE9] => Email address
            [PRO0000038EFCAE9] => Mobile number
            [PRO0000118EFCAE9] => Timezone
            [PRO0000123EFCAE1] => Language
        )
...

…which says that it’s an Array. But this is because all Detective output is processed via PHP code, which supports non-numerical associative arrays, while Javascript does not. So although it’s a valid Array in PHP (and so shows as such when logged), in JS this would actually be an Object.

Yes thanks Bob - got there in the end !!
