Ruby on rails 突然参数错误：种子设定时UTF-8中的字节序列无效

在我的Rails应用程序上工作时，我正在尝试一些裁剪图像的方法，我从，回到我以前拥有的，然后到这个，在完成所有设置后，我决定重新启动数据库并对其进行种子设定，但是当我尝试对数据库进行种子设定时，我得到了

ArgumentError:UTF-8中的无效字节序列

在一些小型研究之前和之后，我从未遇到过这个错误，我发现这是由于一些字符无法被ruby读取，然而，在浏览了我的代码之后，我发现在我开始裁剪图像之前和进一步检查之后，我还没有找到原因

我还没有学会如何读取和跟踪rails/rake bug，这也没有什么帮助，我得到的是：

重要编辑：因此我决定返回到以前的提交，不再处理此问题，出于某种原因，错误不断出现，这让我相信我使用的平台Cloud9存在问题，我还了解到，这不是Rails 5.0上应该出现的问题。不确定，这只是请求URL中的无效字节序列，请尝试以下方法：

添加到您的gemfile
gem'rack-utf8\u Sanitarizer'
或
gem'handle\u无效的\u百分比\u编码请求'
或
gem'utf8 cleaner'
在运行
bundle install
后，我发现了问题的原因，我使用
mount\u uploaders
进行单一上传，将上载设置为数组，从而创建错误。将其更改为
mount\u uploader
是解决方案，您确实需要注意这些细节，好吧，这是您的经验教训。我建议关闭这个问题，除非它对新手有些帮助。
装载上传者需要一个数组，因此您的seed.rb文件应该设置为接受数组

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

不是这样的：
Model.create（images:image1.jpg）
它们都不起作用，仍然会出现相同的错误。这真的很奇怪。在你的config/application.rb中添加以下行：
config.middleware.use'Utf8Sanitizer'
我得到
NameError:main:Object未定义的局部变量或方法'config'
即使在安装了Gem之后，也要在app/middleware中将utf8\u sanitizer.rb添加到你的Rails 3.2项目中，通过我返回的这个链接到以前的提交，现在我也得到了这些错误，显然rails应该总是自动处理这个问题，除非我使用的是2.0之前的版本，现在我使用的是5.0，知道为什么会发生这种情况吗？你使用的是什么版本的Ruby？您是否确保编辑器以UTF-8格式保存文件？该模型的种子文件是什么样子的？将种子添加到问题中，我使用的是ruby 2.3.0，如何确保编辑器以UTF-8保存？直到现在，我一直认为这是理所当然的。
