检查集合中是否存在某些参数
Check for presence of some parameter in a set
我的搜索引擎从参数中检索了一些搜索过滤器，但如果没有 "filter" 参数，我需要做其他事情。
我之前在做
params.slice(*filter_params).any?
但我现在得到了
DEPRECATION WARNING: Method any? is deprecated and will be removed in Rails 5.1, as ActionController::Parameters no longer inherits from hash. Using this deprecated behavior exposes potential security problems. If you continue to use this method you may be creating a security vulnerability in your app that can be exploited. Instead, consider using one of these documented methods which are not deprecated: http://api.rubyonrails.org/v5.0.0.rc1/classes/ActionController/Parameters.html
我不确定我可以做什么来替换这里的 .any? 调用？
您可以将其替换为 Object#present?:
params.slice(*filter_params).present?
您可以在 params 上调用 .to_h 以获取您习惯的哈希方法。
你可以使用!.blank？或者 !.empty?
