Detailed:
ln -s full/path/to/installed/app/folder path/to/folder/with/symlinks/in/your/project
and then run
django-admin.py makemessages --locale=*lang* --symlinks
for instance if i want translate django-tagging
:
ln -s /home/user/python_projects/agregator_gitlab/venv/lib/python3.6/site-packages/tagging /home/user/python_projects/agregator_gitlab/agregator/site_aggregator_backend/extra-locales/tagging
(my manage.py locates agregator/site_aggregator_backend/manage.py
)
and
django-admin.py makemessages --locale=uk --symlinks
and all work perfectly!
