Purpose of the task, is to prevent users from inadvertently creation/opening countries from country_id fields. Countries should be managed from their dedicated menu item. so in this commit, we have set both no_open and no_create to True so user should not update and create a country from the many2X fields. closes odoo/odoo#63773 Taskid: 2241677 Related: odoo/enterprise#15464 Signed-off-by: Yannick Tivisse (yti) <yti@odoo.com>
