Activating the Flask debugger when running under mod_wsgi

flask, mod-wsgi

Solution

As described in the Flask documentation at:

http://flask.pocoo.org/docs/quickstart/#debug-mode

use:

app.debug = True

Under mod_wsgi you aren't doing the app.run() though.

Ensure you are setting 'app.debug' at global scope and not in a conditional section where checking whether __name__ is __main__.

Problem

How can I activate the Flask debugger when running under mod_wsgi? I have `DEBUG`, `PROPAGATE_EXCEPTION` and `PRESERVE_CONTEXT_ON_EXCEPTION` set to `True`, but still the debugger doesn't appear on exceptions.
