如何覆盖 Odoo v.9 中的 search_read() 方法？

Question

受影响的版本：9.0

我正在尝试根据类别限制某些产品。

我有重写 name_search() 方法，它适用于 Many2one 字段。但是当我从 Many2one 字段中的搜索更多选项中搜索产品或从列表视图中的搜索菜单中搜索产品时，它会向我显示该产品。

我试过以下代码：

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

但它给了我以下追溯。

应该是这样的：

@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
