Question 1

How do I customize which panels show in flask-debugtoolbar?

Accepted Answer

You can customize panels by setting the DEBUG_TB_PANELS configuration option in your Flask app. The documentation lists available panels, and you can add or remove them based on your debugging needs, such as focusing on SQL queries or template performance.

Question 2

Flask-debugtoolbar vs using Flask's built-in debugger?

Accepted Answer

Flask-debugtoolbar provides a browser-based interface with detailed panels for proactive monitoring during development, while Flask's built-in debugger is more for handling exceptions after they occur. The toolbar is better for real-time insights into requests and performance.

Question 3

Why isn't the toolbar appearing even with debug mode on?

Accepted Answer

Common issues include missing SECRET_KEY configuration, incorrect template rendering, or conflicts with other Flask extensions. Ensure the app is properly initialized and check for JavaScript errors in the browser console.

Question 4

Can I use flask-debugtoolbar with Flask-SQLAlchemy?

Accepted Answer

Yes, it works seamlessly with Flask-SQLAlchemy, displaying SQL queries and performance metrics in the toolbar panels. No additional setup is needed beyond standard integration, making it ideal for database debugging.

Question 5

Is there a way to disable the toolbar for specific routes?

Accepted Answer

Yes, you can disable it for specific routes by using configuration options or middleware hooks. For example, set DEBUG_TB_INTERCEPT_REDIRECTS to false or create custom logic to skip injection based on request paths.

Question 6

What are the performance impacts of using flask-debugtoolbar?

Accepted Answer

It adds minimal overhead during development, such as slight increases in response time due to data collection and injection. However, this is acceptable for debugging purposes and should not be used in production where performance is critical.
