Firebug
SQL
- http://www.djangosnippets.org/snippets/1962/ Output sql_queries in Firebug console when in debug mode… 
Add this code to the end of the <body> of your main template and it
will print out all your SQL queries with timings in the Firebug console:
{% if debug %}
<script type="text/javascript">
  {% for q in sql_queries %}
    console.debug("({{ q.time }}s)", "{{ q.sql|escapejs }}");
  {% endfor %}
</script>
{% endif %}
This uses the “django.core.context_processors.debug” template context
processor, which requires that DEBUG=True and that your IP address is
listed in INTERNAL_IPS.
