MQL Panel

This panel for Django Debug Toolbar provides insights into MongoDB queries executed during a request similar to how the SQL panel works for relational databases.

Features:

• View all MongoDB queries (MQL) executed during a request
• See query execution time and identify slow queries
• Re-execute read operations (aggregate) directly from the toolbar
• Explain query execution plans
• Color-coded query grouping for easy identification
• Detailed query statistics and performance metrics

Configure the MQL Panel

First, install and configure Django Debug Toolbar by following their installation instructions.

1. Add to INSTALLED_APPS in your Django settings:

INSTALLED_APPS = [
    # ...
    "django_mongodb_extensions",
    # ...
]

2. Add the MQL Panel to your debug toolbar configuration:

DEBUG_TOOLBAR_PANELS = [
    "debug_toolbar.panels.history.HistoryPanel",
    "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",
    # Add this:
    "django_mongodb_extensions.mql_panel.MQLPanel",
    "debug_toolbar.panels.templates.TemplatesPanel",
    "debug_toolbar.panels.staticfiles.StaticFilesPanel",
    "debug_toolbar.panels.cache.CachePanel",
    "debug_toolbar.panels.signals.SignalsPanel",
    "debug_toolbar.panels.redirects.RedirectsPanel",
    "debug_toolbar.panels.profiling.ProfilingPanel",
]

3. Optional: Configure settings.

# Maximum number of documents to return when re-executing select
# queries (default is 100).
DJDT_MQL_MAX_QUERY_RESULTS = 25

# Queries slower than this threshold (in milliseconds) are highlighted
# in the debug toolbar (default is 500 ms).
DJDT_MQL_WARNING_THRESHOLD = 1000
