我正在将Rails 4.1.8应用程序(也使用rails-api~> 0.3.1)升级到4.2.0.rc2,并希望保留respond_with功能.我已经在Gemfile中添加了响应器,但是当我bin / rake规范时,我得到：
/Users/sloveless/.gem/ruby/2.1.0/gems/actionpack-4.2.0.rc2/lib/action_controller/Metal/mime_responds.rb:10:in `respond_to': The controller-level `respond_to' feature has been extracted to the `responders` gem.

任何想法,为什么我可能会得到这个？ ……当然,我怎么能绕过它呢？

编辑：毫不奇怪,这种情况发生在我手动发出请求时,而不仅仅是在测试期间.
解决方法
以下使用rails-api / active_model_serializers 0.8.3为我工作：
去掉
include ActionController::MimeResponds include ActionController::ImplicitRender
加
include ActionController::RespondWith
