こんにちは、私がajax呼び出しをしているとき、私はコンソールでこれを取得しています:
POST http://127.0.0.1:8000/registration/check/username/ 500 (INTERNAL SERVER ERROR)
また、このリンクをクリックすると、次のように表示されます。
DoesNotExist at /registration/check/username/
User matching query does not exist.
Request Method: POST
Request URL: http://127.0.0.1:8000/registration/check/username/
Django Version: 1.3
Exception Type: DoesNotExist
JQuery:
function check_username() {
$("#id_username").change(function() {
var user = $("#id_username").val();
var status = $("#id_username").nextAll(".status").first().empty();
var checking = '<img src="/site_media/images/loader.gif" align="absmiddle"> Checking availability...';
var success = '<img src="/site_media/images/tick.gif" align="absmiddle">';
var e_length = '<p>User name have to be longer</p>';
if (user.length >= 3) {
status.append(checking);
$.ajax({
url: "/registration/check/username/",
type: "POST",
data: { username : $("#id_username").val() },
dataType: "text",
success: function(msg) {
if (msg == '1') {
status.append(success);
}
else {
status.append("This username is already in use");
}
}
});
}
else if (user.length <= 3 && user.length != 0) {
status.append(e_length);
}
else {
status;
}
});
}
