Question

I have used gem 'nested_form', '~> 0.3.2' with rails 4, i have to add two fields on click of link_to_add helper method of nested form? How will i customize the javascript of nested form to add for this specific scenario?

Answer 1

I did this using jQuery:

$(document).on('nested:fieldAdded', function(event) {
    for (var n = 1; n; n--) {
        if ($('.fields').length < 2) {
            event.field.clone().insertAfter(event.field);
        }
    }
});
