[ckan-dev] Increasing log verbosity for certain errors

[Stefan Oderbolz]

Hi Alex,

you have multiple options, depending on where the error occurs:

- if you configured the error mails, you might get a pretty decent error
log including a trace by mail
- if the error happens in the frontend, I would try to run CKAN with
"paster serve" and enable the debug mode, then you get a good idea of where
the error is as well
- the last option is to actually print the trace yourself (by using
try/except), here the python package "traceback" is very handy (
https://docs.python.org/2/library/traceback.html) e.g.

import traceback
try:
    # some code raising an exception
except Exception, e:
    print "An error occured: %r" % e
    traceback.print_exc()
    # or if you are using a logger
    log.exception("An error occured: %r, %s" % (e, traceback.format_exc()))


Hope this helps.

- Stefan
