ugettext_lazy instead of ugettext for locale?

Hello,

I'm not sure if this is a bug, so I wanted to post here first to confirm.

We want to support a french locale in Horizon and reviewed/modified the PO file to make sure it had proper entries for all supported areas. However, when switching from English to French, we find that not all areas are translated even though they are marked translatable in the code ( _("Foobar")).

I was able to resolve this issue by changing

from django.utils.translation import ugettext as _
to
from django.utils.translation import ugettext_lazy as _

This change enabled previously untranslated areas to become translated. The reason for this is described and further linked here (http://stackoverflow.com/questions/2694798/django-form-and-i18n).

An example of this can be seen by doing the above fix to "dashboards/nova/instances/workflows.py" (Folsom).

Can anyone confirm if this is a known issue or if this is a newly discovered bug?

Thanks,
Joe
