本文实际上是对 default_get 方法的应用，当视图被打开时，就会执行此方法。本文以图书整理到书架举例说明使用方法。
创建向导py文件： wizards/wizards_organize_books.py
class WizardOrganizeBooks(models.TransientModel): _name = "wizard.organize.books" _description = "wizard.organize.books" shelf_id = fields.Many2one('zerone.shelf', index=True, string="书架") book_ids = fields.Many2many('zerone.book', string='图书') def action_organize(self): pass创建向导xml文件： wizards/wizards_organize_books.xml

class WizardOrganizeBooks(models.TransientModel): _name = "wizard.organize.books" _description = "wizard.organize.books" shelf_id = fields.Many2one('zerone.shelf', index=True, string="书架") book_ids = fields.Many2many('zerone.book', string='图书') def action_organize(self): pass @api.model def default_get(self, fields): res = super(WizardOrganizeBooks, self).default_get(fields) active_ids = self.env.context.get('active_ids') book_ids = self.env['zerone.book'].browse(active_ids).mapped("id") if self.env.context.get('active_model') == 'zerone.book' and active_ids: res['book_ids'] = [(6, 0, book_ids)] return res应用时，需注意的项，active_ids 就是勾选的记录的id集合，active_model 判断当前模型，如果打开向导时，模型为 zerone.book 时，才执行如下代码。
