I am trying to use django-degub-toolbar in my django app and below are my settigns

DEBUG_TOOLBAR_PANELS = (
    'debug_toolbar.panels.version.VersionDebugPanel',
    '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',
)

MIDDLEWARE_CLASSES += [
'debug_toolbar.middleware.DebugToolbarMiddleware',
]

django.core.exceptions.ImproperlyConfigured: Error importing debug panel debug_toolbar.panels.settings_vars: "No module named settings_vars"

How to solve and why the above error has been encountered ?

Answer 1

The settings_var panel cannot be found. It seems you use an older version of the configuration. Panels have been renamed recently, the new configuration for version 1.0 is:

DEBUG_TOOLBAR_PANELS = [
    'debug_toolbar.panels.versions.VersionsPanel',
    'debug_toolbar.panels.timer.TimerPanel',
    'debug_toolbar.panels.settings.SettingsPanel',
    'debug_toolbar.panels.headers.HeadersPanel',
    'debug_toolbar.panels.request.RequestPanel',
    'debug_toolbar.panels.sql.SQLPanel',
    'debug_toolbar.panels.staticfiles.StaticFilesPanel',
    'debug_toolbar.panels.templates.TemplatesPanel',
    'debug_toolbar.panels.cache.CachePanel',
    'debug_toolbar.panels.signals.SignalsPanel',
    'debug_toolbar.panels.logging.LoggingPanel',
    'debug_toolbar.panels.redirects.RedirectsPanel',
]
