由gem生成的沉默弃用警告

Question

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 <top (required)> 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 <top (required)> 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 <top (required)> 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.

Answer 1

ActiveSupport::Deprecation.silenced = true

Answer 2

根据文档http://api.rubyonrails.org/classes/ActiveSupport/Deprecation/Behavior.html：

设置行为仅影响启动后发生的弃用。gems 引发的弃用警告不受此设置的影响，因为它们发生在 Rails 启动之前。

但是，我确实发现，如果您在需要宝石之前设置它，它将使警告静音。

例如，放置这一行：

ActiveSupport::Deprecation.behavior = :silence

前

Bundler.require(*Rails.groups)

它应该使 gem 警告静音。
