Question

我收到以下错误。这与权限有关。当我通过操作调用自定义方法时，会发生错误。该自定义方法将使用ElementTree库创建一个.xml。

该方法中的代码大约有1500多行，因此将其放入此处并不是最佳选择。但是我认为尝试以下方法会被拒绝

tree.write("20100066603-01-F001-1.xml", "ISO-8859-1", True)

这是错误。 Odoo返回

我已经在PyCharm上尝试了相同的代码，并且可以正常工作。因此，我相信这是有关Odoo权限的问题。 如何为我的模块设置创建，编辑和删除其创建的文件的权限？

PD：如果不太可能在Odoo.sh上实现，那么如何在本地安装上实现呢？我目前都有。

使用命令chmod 777 *，这将允许对您所有自定义模块的各种访问，并且如果您只想允许一个模块使用模块名而不是*，例如 chmod 777 module_name

在Odoo11（Odoo.sh）上使用ElementTree编写xml文件时出现“权限错误”（被拒绝）
