ruby-on-rails - Rails 变形保留字？

Question

我试图生成这样的模型：

rails g scaffold Octopus field1:string, field2:string, ...

这向我抛出了这个错误消息：

[WARNING] The model name 'Octopus' was recognized as a plural, using the singular 'Octopu' instead. Override with --force-plural or setup custom inflection rules for this noun before running the generator.

这给了我octopu我不想要的单数版本。因此我打开了 inflections.rb 并插入了这个：

ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.irregular 'octopus', 'octopuses'
end

但现在我明白了：

The name 'Octopus' is either already used in your application or reserved by Ruby on Rails. Please choose an alternative and run this generator again.

知道我做错了什么吗？
