The ":nothing" option is deprecated and will be removed in Rails 5.1
提问by Linus Oleander
This code in rails 5
这段代码在 rails 5
class PagesController < ApplicationController
def action
render nothing: true
end
end
results in the following deprecation warning
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.
How do I fix this?
我该如何解决？
回答by Linus Oleander
According to the rails source, this is done under the hood when passing nothing: truein rails 5.
根据rails 来源，这是在通过nothing: truerails 5时在引擎盖下完成的。
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
Just replacing nothing: truewith body: nilshould therefore solve the problem.
因此，只需替换nothing: truewith 即可body: nil解决问题。
class PagesController < ApplicationController
def action
render body: nil
end
end
alternatively you can usehead :ok
或者你可以使用head :ok
class PagesController < ApplicationController
def action
head :ok
end
end
