This middleware will add a log of the SQL queries executed at the bottom of every page. You can (should) use BeautifulSoup to place this in a specific location.

Note: If you serve non-html content, it would be wise to do a mimetype check.

this worked great but I had to add the following line to return a response

...

response.content = "%s%s" % ( response.content, t.render(Context({'sqllog':connection.queries})))

return response

I improved Snippet 161 in Snippet 344.

It counts duplicated SQL queries.
