I have used 'flags': {'initial_mode': 'edit'} to open record in edit mode in Odoo 10.
but its not working in odoo 12. Do we have any alternative of this.
res = { 'name': action.name, 'help': action.help, 'type': action.type, 'views': [(form_id, 'form')], 'view_mode': 'action.view_mode', 'target': action.target, 'context': action.context, 'res_model': action.res_model, 'flags': {'initial_mode': 'edit'}, 'res_id': record.id }
