由gem生成的沉默弃用警告

我在我的Rails 5.0.0.1应用程序中使用unscoped_associations gem.

我收到这个弃用警告:

DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. From module, you can access the original method using super. (called from  at /home/rhl/myapp/config/application.rb:8)
DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. From module, you can access the original method using super. (called from  at /home/rhl/myapp/config/application.rb:8)
DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. From module, you can access the original method using super. (called from  at /home/rhl/myapp/config/application.rb:8)

如何在生产环境中消除此警告？

我试过添加:

config.active_support.deprecation = :silence

在 production.rb

但它不起作用.

ActiveSupport::Deprecation.silenced = true
