Question

我有以下参数声明：

protocol TestProt {
    init()
    func testMe() -> String
}

class Factory {

    static public func getObject<T: TestProt>() -> T {
        return T();
    }
}

let object: MyObject = Factory.getObject()
let object: override_MyObject = Factory.getObject()

但收到以下错误：

方法to_hash已弃用，将在Rails 5.1中删除，如 def line_item_params params.require(:line_items).map do |p| ActionController::Parameters.new(p.to_hash).permit(:quantity, :price, :menu_item_id) end end不再继承哈希值。运用这种弃用的行为暴露了潜在的安全问题。如果你继续使用此方法您可能正在创建安全性您的应用中可以利用的漏洞。相反，考虑一下使用其中一个未弃用的文档化方法： http://api.rubyonrails.org/v5.0.1/classes/ActionController/Parameters.html

我只是发布一系列项目。应如何处理？

您可以通过将哈希选项传递给"settings": { "number_of_shards": 5, "number_of_replicas": 1, "index.query.default_field":"test", "index.refresh_interval" : "5s", "index.mapper.dynamic": false , "analysis": { "filter": { "ngram_filter": { "type": "ngram", "min_gram": 2, "max_gram": 18, "token_chars": [ "letter", "digit" ] } }, "analyzer": { "ngram_analyzer": { "type": "custom", "tokenizer": "standard", "filter": [ "lowercase", "ngram_filter" ] } } } }并使用包含嵌套对象白名单键的数组来将对象数组列入白名单。

带有项数组的Rails 5.1的to_hash和strong_parameters
