Question

这是我的第一次Heroku部署，我有一个奇怪的问题，我似乎无法弄清楚。我的应用有一个嵌套表单，当您创建Product时，您可以添加Skus。这一切在Dev中都很有用，但是当部署到Heroku时，嵌套表单会将Skus拒绝为空白。我已单独添加Skus（Product表单之外）并且工作正常，此外还有Dimensions表单中的嵌套Product字段可以正常保存。它似乎是它不喜欢的嵌套Skus。

奇怪的是，日志似乎表明在提交表单时Skus存在嵌套属性。

我得到的错误是表单被踢回来并说：Skus can't be blank

另外，我不明白为什么在Parameters被截断的日志文件中，它是如何在Heroku日志中显示的？

关于这一点的另一个奇怪的事情是我没有对Skus进行任何验证，据我所知Product即使Sku也应该可以保存是空白的。

对于故障排除或调查途径的任何建议将不胜感激。

Answer 1

所以我不是100％确定问题是什么，但我已经解决了。我最终删除了任何与skus有关的东西，然后慢慢地将它逐渐添加回来。

我认为最有可能导致这个问题的是我有一个我重命名的Product类的版本，因为我没有使用它，并且不想忘记我的工作完成（我知道，没必要，因为我正在使用git。我猜老习惯很难）无论如何，我已经改变了文件名，但是我忽略了重命名文件中的类定义。这个名字是在我使用的真实Product课程之后。我认为这导致了heroku的冲突。我不明白的是为什么它在我的本地开发环境中没有引起任何问题。

嵌套模型在开发中工作正常，但未在生产中保存
