[GeoNode-users] First implementation of Layer migration scripts using JSON fixtures

Wed Mar 2 08:19:58 PST 2016

Just as a follow up on this,

the script has been converted into a GeoNode management command

https://github.com/GeoNode/geonode/commit/38b9fe1b7279fb16083b163a82406dd5e9d4080e

It can be executed as:

  python manage.py migrate_layers
--backup-file=/home/geonode/geonode/scripts/backup-restore/backup/2016-02-25_180915.zip
--owner=admin

Best Regards,
Alessio Fabiani.
