ODOO13 使用Wizard批量操作數據，如何將勾選的記錄顯示到打開的Wizard視圖中

本文實際上是對 default_get 方法的應用，當視圖被打開時，就會執行此方法。本文以圖書整理到書架舉例說明使用方法。

創建嚮導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="書架")
    book_ids = fields.Many2many('zerone.book', string='圖書')

    def action_organize(self):
        pass

創建嚮導xml文件： wizards/wizards_organize_books.xml

<field name="shelf_id"/>
<field name="book_ids" nolabel="1">
    <tree string="Books">
        <field name="id"/>
        <field name="name"/>
        <field name="email"/>
        <field name="customer_type"/>                       
    </tree>
</field>
....
<footer>
    <button name='action_organize' string='整理' class='oe_highlight' type='object'/>
    <button special="cancel" string="Close" type="object" class="btn btn-secondary oe_inline"/>
</footer>

重寫 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="書架")
    book_ids = fields.Many2many('zerone.book', string='圖書')

    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

應用時，需注意的項，active_ids 就是勾選的記錄的id集合，active_model 判斷當前模型，如果打開向導時，模型爲 zerone.book 時，才執行如下代碼。
