我正在关注Odoo的教程，我必须创建一个新视图来轻松创建/编辑付款方式。在Sales Order中添加many2one字段可以正常工作，但是一旦我添加教程中给出的xml行并进行升级就会出错。重新启动服务会导致内部服务器错误。
init是正确的，所以不应该是问题，没有xml更改的py工作正常。
这是我得到的错误

我不知道该字段未被识别的原因，我将其与教程中的代码进行了比较，但我找不到任何差异。
提前致谢。
编辑： 我尝试重命名字段，然后注销＆＃39;没有给出错误，但名称是＆＃39;场确实。重新命名＆＃39;字段不会更改任何内容，错误会保留在该字段上。
EDIT2： 好吧问题似乎已经解决了，我不知道为什么......在经历了挫折之后再次回来并再次尝试，一切正常，所以是的... 无论如何，谢谢你的帮助！
答案 0 :(得分：1)
同意@HardikPatadia：重新启动重新加载py文件的服务器后，通常会解决您获得的错误（“找不到字段”）。你说重新启动会给你一个内部服务器错误，所以你应该检查Odoo日志文件以查看错误是什么 - 可能是一些python错误。
另一件可能错误的事情是您没有在 init .py中导入py文件，因此无法识别字段。
