django - custom error message for urlinput widget

django 1.7 trying to customize the default client side validation message that gets fired on a model form. Specifically the error message for urlinput widget (the default for a urlfield). This error appears to come from client side validation when the form is submitted.
The target error message

I want to change "Please enter a URL" to something else. I feel like I've looked everywhere but can't find it.

Can anyone help point me in the right direction?

The url type in Html5 will display required attribute message lilke this

Cross browser verbiage:
    Firefox: Please enter a URL.
    Chrome: Please enter a URL.
    IE: You must enter a valid URL

You can use setcustomvalidity

<form action="" method="post">
    {% csrf_token %}
    {{ form }}
    <input type="submit" value="Submit" />
</form>
<script type="text/javascript">
    document.addEventListener("DOMContentLoaded", function() {
    var elements = document.getElementsByTagName("INPUT");
    for (var i = 0; i < elements.length; i++) {
        elements[i].oninvalid = function(e) {
            e.target.setCustomValidity("");
            if (!e.target.validity.valid) {
                e.target.setCustomValidity("This field cannot be left blank");
            }
        };
        elements[i].oninput = function(e) {
            e.target.setCustomValidity("");
        };
    }
})
</script>
