Ruby on rails 名为Spec的模型类存在Rspec问题，没有预期的模型类方法

因此，每次运行模型类规范的RSpec测试时，我都会遇到此错误：

NoMethodError: undefined method `new' for Spec:Module

正如您已经猜到的，您正在看到

Spec

类和类之间的名称空间冲突

这里有两种解决方法

将类及其文件名重命名为Rails.root/models/the_spec.rb

class TheSpec < ApplicationRecord
  belongs_to :scenario

  # ... your code
end

class TheSpec

为类命名名称空间并将其移动到Rails.root/models/internal/spec.rb

class Internal::Spec < ApplicationRecord
  belongs_to :scenario

  # ... your code
end

class内部：：Spec

---

您还需要编辑和移动/重命名您的

spec\u spec.rb

文件以匹配。

我建议您不要命名您的模型

spec

-它可能已经在Rails内部使用过。为它找到另一个名字，看看你的bug是否消失了……我建议你不要给你的模型命名

Spec

——它可能已经在Rails内部使用过了。找到它的另一个名字，看看你的bug是否消失了。。。
