How do I debug error 500's served up by the DJango test server?

Question

I'm trying to debug my DJango Paypal IPN integration but I'm struggling. The Django dev server reports a 500 error to the console (but no other details) and the IPN test tool reports a 500 error but no other details.

I've tried disabling the DEBUG mode to try and get it to send me emails but despite setting up the EMAIL_HOST to something suitable, I'm not seeing any emails. I tried and verifying that the email system is working with a call to send_mail ..but that succeeds and I still see no emails regarding internal server errors.

What could I be missing?

edit

I'm running the dev server from PyCharm and the console output looks like this:

runnerw.exe C:\Python26\python.exe manage.py runserver 192.168.1.4:80
Validating models...

0 errors found

could you post the content of your console (including the command line used to invoke the server)? — dMb

Another thing to try is to launch a simple SMTP server on your machine.

python -m smtpd -n -c DebuggingServer localhost:1025

Which will output on your console all emails headers and body. Make sure localhost and the port 1025 correpond to what you have in your settings.py, respectively in EMAIL_HOST and EMAIL_PORT.

given that you are running a pre-alpha version of django, I would recomment asking this question on the django user list https://groups.google.com/group/django-users

Well spotted; I thought I was using a stable build!

Doesn't answer my question here, but you nailed the other one I had open. Please post this as the answer to that question and I'll accept it as the final answer.. ...because after regressing to 1.3.1 stable it works!

have a look at django-sentry

it logs 500 errors (also supports regular logging), making the dynamic "orange 500 pages" browsable after the fact. this is especially useful when you never get the original error page, e.g. when using ajax or remote apis like your case

i'm only running 1.8, but it has a sentry_testing setting which does work in debug mode. has that been removed?

you might be right. I just wasn't aware this was ever a possibility.
