{% extends "admin/change_list.html" %}
{% block object-tools-items %}
<script>
function export_file() {
    var export_url = '/export';
    var url = window.location.href;
    var params = url.split('?')[1];
    if (typeof(params) == undefined) {
        export_url += '?' + params;
    };
    window.open(export_url);
}
</script>
<li>
