如何重寫Odoo v.9中的search_read（）方法？

Question

受影響的版本：9.0

我嘗試根據類別限制某些產品。

我有重寫name_search（）方法，該方法對於Many2one字段工作正常。 但是，當我從Many2one字段中的“搜索更多”選項中搜索產品或從列表視圖中的搜索菜單中搜索產品時，就會向我顯示該產品。

我嘗試了以下代碼：

class ProductTemplate(models.Model):

    _inherit = "product.template"

    def search_read(self, model, fields=False, offset=0, limit=False, domain=None, sort=None):

        res = super(ProductTemplate, self).search_read(model, fields=fields, offset=offset, limit=limit, domain=domain, sort=sort)

        return res

但這給了我以下的追溯。

問題 ：

1. 如何限制用戶繞過從搜索菜單中選擇產品？

2. 如何覆蓋search_read（）方法？

Answer 1

應該是這樣的：

@api.model
def search_read(
        self, domain=None, fields=None, offset=0,
        limit=None, order=None):
    res = super(ProductTemplate, self).search_read(
        domain, fields, offset, limit, order)
    return res
