log all sql queries

Merge the following snippet with the LOGGING field in your settings.py:

LOGGING = {
    'version': 1,
    'filters': {
        'require_debug_true': {
            '()': 'django.utils.log.RequireDebugTrue',
        }
    },
    'handlers': {
        'console': {
            'level': 'DEBUG',
            'filters': ['require_debug_true'],
            'class': 'logging.StreamHandler',
        }
    },
    'loggers': {
        'django.db.backends': {
            'level': 'DEBUG',
            'handlers': ['console'],
        }
    }
}

Tweaked from @acardenas89 answer

Add the following bold statements in settings.py

if DEBUG:
    import logging
    l = logging.getLogger('django.db.backends')
    l.setLevel(logging.DEBUG)
    l.addHandler(logging.StreamHandler())


LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        },'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },'django.db.backends.sqlite3': {
            'level': 'DEBUG',
            'handlers': ['console'],
        },
    }
}

Maybe check out https://github.com/django-debug-toolbar/django-debug-toolbar

It'll let you see all the queries generated by a given page. As well as stacktraces of where they occur etc.

EDIT: to log all SQL queries to a file etc, then you will want to create some middleware. Middleware gets run on every request. There are several Django snippets out there for this sort of thing:

• http://djangosnippets.org/snippets/290/
• http://djangosnippets.org/snippets/264/

Those are concerned with printing to the terminal, but it wouldn't be hard to adapt them to use python's logging library.
