Debugging

Backend Debugging (Django Webserver)

Attaching to the Container

1. Find the container ID:

docker ps

Look for the container named backend-dev and note its ID.

2. Attach to the container:

docker attach <container_id>

Using ipdb for Debugging

1. Add breakpoints in your code:

import ipdb; ipdb.set_trace()

2. When the breakpoint is hit, you'll enter the ipdb debugger.

3. Use ipdb commands to debug. Common commands:

   • n: Next line
   • c: Continue execution
   • p variable: Print variable

For more commands, refer to the ipdb cheatsheet

Exiting the Debugger

To detach from the container without stopping it:

• Press Ctrl + P, then Ctrl + Q

This sequence allows you to exit while leaving the container running.
