Javascript 呈现.json.erb模板时不调用jQuery.done

我试图通过将响应从create移动到一个视图来清理代码（使用了一些帮助程序，这很有意义）。然而，由于某些原因，我的js回调从未被调用。我100%的困惑，所以这里是我的日志和代码。非常感谢：-）

查看\u controller.rb libraries.js（加载到第页） create.json.erb 来自chrome网络日志中服务器的响应 在行定义之前添加

“

，并将

.html\u safe

添加到json

{
    "review": <%= @review.to_json(only: [:comment, :rating]).html_safe %>,
    "average_rating": <%= number_to_human(@library.average_rating) %>
}

{
“审查”：，
“平均_评级”：
}

您在网络控制台上得到的响应是什么？要显示的已编辑的答案。它似乎返回了正确的数据，但

。完成后将不会调用：-（这是无效的JSON不应该仍然调用
done
吗？很可能它正试图将其解析为JSON，但它失败了，因此不会调用
done
，而
fail
是无效的。
