Small js script that automatically submits the changelist form on field changes. This is convenient when used with https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_editable, and avoids having to remember to submit the form when done (the form on the changelist page doesn't look like a form after all, …

admin_list_editable_autosubmit.js

/*
 * Only useful in changelist pages when the ModelAdmin displayed has 
 * "list_editable" (https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_editable)
 * configured.
 *
 * When one of the input/select/textarea value is changed, automatically submit
 * the form using ajax.
 *
 * Only form fields relevant to the "list_editable" will trigger a form submit.
 *
 * This script uses the jQuery packaged with Django, and already made available
 * in the admin via django.jQuery.
 *
 * An easy way to add this script to the admin is to override the base_site.html
 * admin template (https://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template),
 * and add the following to it:
 *
 *    {% block footer %}{{ block.super }}
 *        <script type="text/javascript" src="{% static "js/admin_list_editable_autosubmit.js" %}"></script>
 *    {% endblock footer %}
