ruby-on-rails - 关于 TypeError 的错误(错误的参数类型模块(预期的类)): app/controllers/player_profiles_controller. rb:1:in `'

Question

我收到如下所示的错误:

TypeError (wrong argument type Module (expected Class)):
app/controllers/player_profiles_controller.rb:1:in `<top (required)>'

什么可能导致上面显示的错误？

我想通过在 SoapUI 中渲染 JSON 来测试结果。

这是错误

配置中的路由

post ':controller/:action' , :format => 'json'

您能向我们展示您在错误消息中引用的代码吗？似乎您将一些错误类型的参数放入它无法处理的方法中。
