我正在尝试输出一个哈希，它是调用 Flickr 的 collection.getTree 方法的结果。
我有：
ap @flickr_collections
它正在打印出散列，但周围有所有转义的 html 标签。我该如何解决这个问题。我确实尝试过.html_safe，但没有奏效。
基本上我想要的只是这个哈希的漂亮打印输出。不多不少。
更新：
这就是我正在运行的：= ap(@flickr_collections, html: true)
输出是：

我不能添加其余的输出，因为我只能在这个框中使用 30,000 个字符。以上是输出的第一部分。
如果我在前面添加一个原始调用ap，那么它确实有帮助，但它会在新行上输出每个字符串、哈希箭头和大括号/方括号，这没有任何用处。
我将不胜感激这个问题被重新打开。
