ruby-on-rails-4 - 如何摆脱 Devise 上的电子邮件正则表达式消息？

Question

我正在使用 Devise Token Auth gem 并且每次我在 Rails 4.2.5 应用程序中运行我的测试套件时，我都会收到来自 Devise 的弃用警告:

DEPRECATION WARNING: [Devise] config.email_regexp will have a new default on Devise 4.1 To keep the current behavior please set in your config/initializers/devise.rb the following:

Devise.setup do |config|
   config.email_regexp = /\A[^@\s]+@([^@\s]+\.)+[^@\W]+\z/
end

If you want to use the new default:

Devise.setup do |config|
   config.email_regexp = /\A[^@\s]+@[^@\s]+\z/
end

. (called from block in tsort_each at /usr/local/lib/ruby/2.2.0/tsort.rb:226)

我已经手动添加了 config/initializers/devise.rb 文件并设置了 email_regex正如上面的消息所建议的那样，但烦人的消息仍然存在。

如何禁用此消息？

与此相关 post ，您可以根据您工作的环境管理弃用警告，如 rails guides 中所述。 :

active_support.deprecation_behavior Sets up deprecation reporting for environments, defaulting to :log for development, :notify for production and :stderr for test. If a value isn't set for config.active_support.deprecation then this initializer will prompt the user to configure this line in the current environment's config/environments file. Can be set to an array of values.

所以只需更改 config/environments/test.rb值 :stderr 为 :log

Rails.application.configure do
   ...
   # Print deprecation notices to the stderr.
   config.active_support.deprecation = :log
   ...
end

有了这个， depecation 警告将在 log/test.log 中。而是在控制台输出中
