python - Odoo 11 元素 '<page name="extra_info">' 无法在父 View 中找到

Question

我正在尝试/学习 Odoo 11。 我只对项目模块感兴趣，但我安装了 CRM、修复等，只是为了看看它们能做什么。当我尝试卸载它们时发生错误并收到以下跟踪:

Error:

我不是一个Python开发人员，我还没有了解Odoo或OpenERP的内部结构来真正能够修复任何问题。我所做的唯一一件事是通过 Odoo 的内部编辑器在看板 View 的项目 -> 任务框中添加了一个 date_start 字段。

我已经在这里和 Reddit 上读过类似的问题，但它没有让我得到任何帮助。

Answer 1

卸载有时会很困惑。 Odoo View 可以通过 XPath 表达式(直接和间接)继承和扩展。

不知何故，您卸载了一个模块，该模型 project.task 的 View 定义依赖于另一个 View ，该 View 将在卸载模块时删除。

您在这里没有犯错误，但 Odoo 本身以错误的顺序卸载模块，或者在项目应用程序/模块中的任何位置存在错误的模块依赖项。

尝试取消模块/应用程序卸载(您必须打开每个模块并单击该按钮...)，然后卸载模块task_check_list，这是此错误的来源。
