不推荐使用":nothing"选项,将在Rails 5.1中删除

Question

这个代码在rails 5中

class PagesController < ApplicationController
  def action
    render nothing: true
  end
end

导致以下弃用警告

DEPRECATION WARNING: :nothing` option is deprecated and will be removed in Rails 5.1. Use `head` method to respond with empty response body.

我该如何解决？

Answer 1

根据导轨源,这在通过nothing: true导轨5 时在引擎盖下完成.

if options.delete(:nothing)
  ActiveSupport::Deprecation.warn("`:nothing` option is deprecated and will be removed in Rails 5.1. Use `head` method to respond with empty response body.")
  options[:body] = nil
end

只需更换nothing: true与body: nil因此应该解决的问题.

class PagesController < ApplicationController
  def action
    render body: nil
  end
end

或者你可以使用 head :ok

class PagesController < ApplicationController
  def action
    head :ok
  end
end
