突然ArgumentError：播种时UTF-8中的无效字节序列

问题描述 投票：1回答：3

在我的Rails应用程序上工作时，我正在尝试某种方式来裁剪图像，我从Rails Casts #182 回到我以前的版本然后再到这个blog post，在完成所有设置之后，我决定重新启动我的数据库并播种它，但是当我试图播种我的数据库时，我得到了ArgumentError: invalid byte sequence in UTF-8。

我在一些小型研究之前和之后从未遇到过这个错误，我发现这是由于某些字符无法被ruby读取，但是，在略读我的代码之后，我发现在开始之前我的内容没有区别剪裁图像，经过进一步检查，我还没找到原因。

我还没有学习如何读取和跟踪rails / rake bug也没有帮助，这是我得到的：

我的主要问题是这个错误究竟发生在哪里？到目前为止，我已经通过经验了解到，它可能是seeds.rb或模型（在这种情况下event.rb）然而我没有看到任何不同，我之前都有它们都工作，我甚至能够上传图像并播种它们没问题，直到我从Rails Cast中实现并删除代码并在博客文章中实现代码，任何进入解决方案的方向都会有很大的帮助。

这是模型的种子，事先做得很好。

重要编辑：所以我决定回到以前的提交只是为了不再处理这个问题，并且由于某种原因错误不断出现，这让我相信我正在使用的平台存在问题，这是Cloud9，我也读过这个不应该在Rails 5.0上发生的问题

我找到问题的原因，我使用mount_uploaders进行单一上传，使上传成为一个数组，从而产生错误。把它改成mount_uploader是解决方案，你真的要注意这些细节，好吧，吸取教训。我建议关闭这个问题，除非它对新手来说有点用处。

不确定，它只是请求URL中的无效字节序列，请尝试以下方法：

在运行gem 'rack-utf8_sanitizer'之后添加到你的gemfile gem 'handle_invalid_percent_encoding_requests'或gem 'utf8-cleaner'或bundle install。

mount_uploaders需要一个数组，所以你的seed.rb文件应该被设置为接受一个数组。

它应该是这样的：Model.create(images: [image1.jpg])

不像这样：Model.create(images: image1.jpg)
