Error handling for validation calls

[dbrgn]

Validation does AJAX requests to check-URLs.

Is it possible to easily add an error-alert if the request fails, @d22?

A possible case where this is needed is if CSRF validation fails (e.g. because the user enabled secure cookies but doesn't use TLS).

Yes, this is possible, the remote validation uses the jQuery ajax object, so this is possible (example from packages.js):

...
remote: {
    url: "/packages/check",
    type: "post",
    error: function () {
        alert('Remote validation failed');
    },
    data: {
        'package': function () {
            return $('#packageId').val()
        },
        'name': function () {
            return $("#name").val()
        },
        csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]', '#packageform').
    }
}
...
