$.ajax() with django fails

Question

I'm trying to get a static file (a js script) from django (development server) using jquery ajax but something is preventing the $.ajax promise to resolve.

Here's my ajax call :

    $.when(
        $.ajax({dataType: "script", cache: true, url: "/static/ajax_upload/js/jquery.iframe-transport.js"}),
        $.ajax({dataType: "script", cache: true, url: "/static/ajax_upload/js/ajax-upload-widget.js"})
    ).then(function() {
        console.log( "Load was performed." );
        AjaxUploadWidget.autoDiscover();
        $("#level-modal").foundation("reveal", "open");
    }, function () { alert("An error occured, try reloading the page."); });

Nothing in the then function is called, success nor failure.

The weird thing is that the same ajax call with files from google works :

    $.when(
        $.ajax({dataType: "script", cache: true, url: "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"}),
        $.ajax({dataType: "script", cache: true, url: "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"})
    ).then(function() {
        console.log( "Load was performed." );
        AjaxUploadWidget.autoDiscover();
        $("#level-modal").foundation("reveal", "open");
    }, function () { alert("An error occured, try reloading the page."); });

I think something might be wrong with my responses headers but I get a 200 status and I ain't an expert in Http.

Response from django :

Answer 1

After going through everything I could think of,
I finally found the problem.
It was dajaxice. It is apparently overriding some things in jquery.
After commenting it out, I was able to get the normal behavior.

I found out that the problem can be resolved for people using jquery by adding DAJAXICE_XMLHTTPREQUEST_JS_IMPORT = False in your settings.py
