ODOO13 使用Wizard批量操作数据，如何将勾选的记录显示到打开的Wizard视图中

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

    
        
        
        
                               
    

....

    
    

重写 default_get 方法

​
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。
