问题
Tried with python migrate.py --config=/etc/openerp/openerp-server.conf --database=test_data --run-migrations=9.0
Outcome: Failed, fallback on creating empty database + loading a dump running migration for 9.0
Log file/ migration.log/:
UndefinedColumn: column ir_attachment.res_field does not exist
Could anybody give a hint or help? Much appreciated.
