安裝Typus rails插件后的`load_missing_constant'

Question

收到一個奇怪的錯誤。 剛剛安裝了Typus rails admin插件，該插件應該在2.3.2中工作。 但是，安裝后似乎與我的用戶模型混在一起。 不知道從哪里開始，有什么想法嗎？

Answer 1

您正在使用restful_authentication嗎？

如果是這樣，restful_authentication提供的“身份驗證”模塊與Typus中包含的模塊之間存在名稱沖突。

我將所有對restful_authentication模塊的引用從Authentication重命名為RestfulAuthentication，並在vendor / plugins / restful_authentication / lib / authentication.rb中更改了模塊名稱。 不知道是否有更好的方法指定模型應使用哪個模塊。

Answer 2

或者，您可以在Restful Authentications前面加上::來清除差異，

::認證而不是認證
