我正在尝试在我的应用的rails控制台中初始化一个新用户。每当我输入初始化代码时：
irb(main):001:0> user = User.new
我收到此错误：
(Object doesn't support #inspect)
=>
irb(main):002:0>
我已正确设置用户凭据，并且没有任何错误使用代码的方法。

User对象的实例化及其对user变量的赋值似乎工作得很好，所以我希望你确实有一个新的User实例存储在user。虽然您在User课程中包含的某些代码未定义User的{{1}}方法，但似乎会出现。
Ruby中的所有类（包括您的#inspect类）都继承自User类，Object定义了一个名为Object的实例方法。 inspect通常调用#inspect来返回对象的字符串表示形式。 IRB使用此方法生成在方法定义时通常会看到的输出。
您应该能够看到自己如何定义#to_s：
#inspect因此，如果您愿意，可以提供自己的class User
def inspect
"custom implementation of #inspect"
end
end
irb(main):001:0> user = User.new
=> custom implementation of #inspect
irb(main):002:0>
，但您需要这样做很奇怪。如果您想要跟踪此问题，我会查看您在#inspect中显示的代码（显然只是User）并尝试查找Mongoid::Document未定义的位置和原因。

我发现自己在Auth::user()中使用了这样的自定义设计path_names
routes.rb
当我删除路径名时，错误消失了。
希望有一天能对某人有所帮助。
