ok, just for others if they will get into this stupid things as I did, don't forget to have the category.rb in the app/models..
好的，对于其他人来说，如果他们会像我一样陷入这种愚蠢的事情，请不要忘记在应用程序/模型中包含 category.rb ..
class Category < ActiveRecord::Base
...

For me, i got the similar problem in the views. My Category model is available inside namespace example
对我来说，我在视图中遇到了类似的问题。我的类别模型在命名空间示例中可用
Module Financial class Category end end
When i call simply Category.get_method. It was giving same error. so that i modified into Financial::Categorythat solved my problem.
当我简单地调用 Category.get_method 时。它给出了同样的错误。所以我修改为Financial::Category解决了我的问题。

I was using a PORO and it wasn't loading, giving me this error. It was because I had changed the class name without changing the file name.
我正在使用 PORO 但它没有加载，给我这个错误。那是因为我在没有改变文件名的情况下改变了类名。
回答by Wellington1993
How the others suggested I had a similar problem solved be fix of wrong model name.
其他人如何建议我解决了类似的问题是修复了错误的模型名称。
