[ckan-dev] Translators and threads

Tue Apr 19 09:24:18 UTC 2011

Hi all,

I have a question related with translators and threads, and I was
hoping somebody could give me a clue.

I'm using the new logic functions in ckan core to create/edit packages
from the import stage of the harvesting process, which runs on a
queue. When the logic functions found an error, they use the
underscore function to i18nize the message:
_('Package not found') or whatever

The problem is that then I get an error like this one:

TypeError: No object (name: translator) has been registered for this thread

(Full traceback at the end of the email)

I guess it's related with the code running on a different thread. Does
anyone know how "to register the translator for this thread"?

Thanks,

Adrià
