How do I debug properly using Eclipse and Pydev?

Question

I have got Pydev configured properly so it runs my app, however when I want to inspect/trace my code by setting up breakpoints the debugger does not kick in (can\'t trace). Does

Answer 1

--noreload option is crucial, otherwise server will fork and your breakpoint won't trigger.

Answer 2

Ordinarily you wouldn't have to select manage.py and hit debug. From your description it sounds like you may not have set up the Django launch params in the Run/Debug settings panel.

Here are some step by step instructions:

The important part is adding the entry to the Run/Debug settings. When it's time to debug, set the breakpoint, on the Eclipse toolbar click on the Debug button's drop-down arrow and select the Django project you've defined. Then from a browser window go to your Django server's URL. Eclipse should stop at the breakpoint.

Answer 3

If you're debugging the Django runserver, make certain you specify the --noreload command line parameter. Otherwise the debugger ends up looking at the wrong python instance and never trips any breakpoints.

Answer 4

Ok I think I found what my problem was. I had to set the breakpoint on the def statement in views.py instead of the statements after it.
