警告:函数Magnify.User.__struct__/0未定义

Question

我刚刚为我的Phoenix项目安装了Coherence，但是当我运行我的本地服务器时，我得到了以下警告消息，任何想法为什么。

更新了用户和模式，这是由Coherence创建的，我没有创建它，它都在下面。

同样不确定是什么导致了这一点，我理解是一致性造成了这一点。

核心问题是它需要Magnify.User模块，但我的模块是Magnify.Coherence.User，如果您搜索Magnify.User，我会找到以下内容

config :coherence,
  user_schema: Magnify.User,
  repo: Magnify.Repo,

需要将user_schema: Magnify.User更改为Magnify.Coherence.User
