How do I know which field is invalid on a knockout check?
I have a rather large knockout model and I want to check all nested models in it:
self.errors = ko.validation.group(self, { deep: true });
The validator encountered an error:
> self.errors()
["This field is required."]
I don't know which field of my huge model is wrong. How can I find out?

I think you should be looking for something like this
// Getting errors
var errors = ko.validation.group(this, {
deep: true,
observable: false
});
// New method: getting extended details
var details = errors.getDetails();
for (var i = 0; i < details.length; i++) {
var d = details[i];
/*
Every element contains the following fields:
"observable" - a reference to the target observable.
"error" - the error message.
"rule" - the name of the failed validation rule.
"data" - an object that contains extension data (provided via "extend" method) for every rule. E.g. "data.required == true".
*/
}
PS: You need to add a few lines to the validation file to make the job work getDetails()
i.e. which may be missing from the validation script file (see link link and validation code)
