Django Debug Toolbar not displaying SQL

Question

I recently installed django-debug-toolbar. The toolbar works and I can see the tabs on the side. However, nothing shows up in the SQL tab even when I have obviously executed an SQL query (such as in the admin):

My settings are as follows:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2'
        'NAME': 'mydatabase'
         ....
    }
}

# Backwards compatability with apps
DATABASE_ENGINE = DATABASES['default']['ENGINE'].split('.')[-1]
DATABASE_NAME = DATABASES['default']['NAME']

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'debug_toolbar.middleware.DebugToolbarMiddleware',
)

INSTALLED_APPS = (
    ...
    'debug_toolbar',
    ...
)

# Settings for the django-debug-toolbar
DEBUG_TOOLBAR_PANELS = (
    'debug_toolbar.panels.version.VersionDebugPanel',
    'debug_toolbar.panels.cache.CacheDebugPanel',
    'debug_toolbar.panels.timer.TimerDebugPanel',
    'debug_toolbar.panels.settings_vars.SettingsVarsDebugPanel',
    'debug_toolbar.panels.headers.HeaderDebugPanel',
    'debug_toolbar.panels.request_vars.RequestVarsDebugPanel',
    'debug_toolbar.panels.template.TemplateDebugPanel',
    'debug_toolbar.panels.sql.SQLDebugPanel',
    'debug_toolbar.panels.signals.SignalDebugPanel',
    # 'debug_toolbar.panels.logger.LoggingPanel',
)

def custom_show_toolbar(request):
    return request.user.is_staff

DEBUG_TOOLBAR_CONFIG = {
    'INTERCEPT_REDIRECTS':False,
    'SHOW_TOOLBAR_CALLBACK':custom_show_toolbar,
    'SHOW_TEMPLATE_CONTEXT':True,
    'HIDE_DJANGO_SQL':False,
}

I'm using Django 1.3 with Toolbar version 0.8.5. Any help with this problem would be awesome...

Edit: Based on the answer, I have decided to post how I am handling my view functions:

def func1(query, var1):
    query = query.filter(var__icontains=var1)
    return query

def func2(query, var2):
    query = query.filter(var__icontains=var2)
    return query

def parse(**kwargs):
    # Based on some logic call func1 and func2
    return query

def view(request, template="display.html"):
    # Do some request processing
    query = parse(request.GET.items())
    return render(request, template, { 'items':list(query) })

Make sure that you are running your SQL in the same thread that handled the request.

The Django debug toolbar only seems to take a look at the SQL statements that are run in the current thread and assumes that these are the only ones that are related to the request that was handled.

I have the same problem, and I found the solution in my case. I am using python 2.5 on Windows Vista. There are 2 problems.

First, the "format" function which is supported from python 2.6 are used in the debug_toolbar.panels.sql module. I fixed this using "%" operator(line 194).

stacktrace.append('<span class="path">%s/</span><span class="file">%s</span> in <span class="func">%s</span>(<span class="lineno">%s</span>)\n <span class="code">%s</span>"' % (params[0], params[1], params[3], params[2], params[4]))

Second, in the same module, '/' character is used as a separation character. Because of this, it does not work on Windows. I changed the separation character and it went well.

I just find out a way:

• right click on "default"
• click inspect element
• find the nearby table which has style="display:none"
• edit the style attribute to remove it

I don't know why I have to do all that ...
