Answer 1

您不能在action_purchase_orders 视图操作中执行此操作，您不能在域元组右侧使用字段，因为将没有上下文来提供该值。要完成它，您需要将按钮更改为 object 类型，并使用关联的 python 方法返回具有所需域值的操作 dict 评估，因此域仅包含其右侧元组的值。 Like（查看按钮的新类型和名称）：

<button type="object" name="action_purchase_orders" class="oe_stat_button" icon="fa-list-alt" attrs="{'invisible':[('purchase_order_count', '=', 0)]}">
    <field name="purchase_order_count" invisible="1"/>
    <field name="purchase_order_ids" string="Purchase Orders" widget="statinfo" help="Purchase orders"/>
</button>

在您的 purchase.form 模型中定义方法 action_purchase_orders，例如：

@api.multi
def action_purchase_orders(self):
    self.ensure_one()
    return {
        'name': _('Purchase Orders'),
        'type': 'ir.actions.act_window',
        'view_type': 'form',
        'view_mode': 'form',
        'res_model': 'purchase.order',
        'target': 'new',
        'domain': [('id', 'in', self.purchase_order_ids.ids)]
        'context': self.env.context.copy(),
    }

Answer 2

添加与 purchase.order 的关系

class PurchaseOrder(models.Model):
_inherit = 'purchase.order'

   purchase_form_ids = fields.Many2many('purchase.form', 'purchase_form_purchase_order_rel', 'purchase_order_id', 'purchase_form_id', 'Purchase Orders')

并将操作视图更改为

<record model="ir.actions.act_window" id="action_purchase_orders">
    <field name="name">Purchase Orders</field>
    <field name="type">ir.actions.act_window</field>
    <field name="res_model">purchase.order</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form</field>
    <field name="domain">[('id', 'in', purchase_form_ids.ids)]</field> 
</record>
