[ckan-dev] Question about singular/plural translation

Fri Jan 15 10:42:34 UTC 2016

Hi Stefan,

First of all I don't know if you are aware that starting on CKAN 2.5
there's a much more convenient way to handle translations from
extensions using some interfaace and default locations for folders:

http://docs.ckan.org/en/latest/extensions/translating-extensions.html

ckanext-harvest and others use it already:

https://github.com/ckan/ckanext-harvest/tree/master/ckanext/harvest/i18n

I'll mark the wiki page you mention as deprecated.

As for your particular issue, I'm not sure what's going on. On the
resulting catalog, do you have two separate entries, one for the
singular and one for the plural variant? eg

msgid "Organization"
msgstr "Organisation"

msgid "Organization"
msgid_plural "Organizations"
msgstr[0] "Organisation"
msgstr[1] "Organisationen"
