我有一个像
这样的值的对象%{"Friday" => [], "Monday" => [], "Saturday" => [], "Sunday" => ["3:0-4:0", "6:0-7:0"], "Thursday" => [], "Tuesday" => [], "Wednesday" => []}
我想在我的电子邮件模板的视图中显示它，我刚才声明为
<p>Schedule: <%= @schedule %></p>
我收到了这个错误
** (Protocol.UndefinedError) protocol Phoenix.HTML.Safe not implemented for %{"Friday" => [], "Monday" => [], "Saturday" => [], "Sunday" => ["3:0-4:0", "6:0-7:0"], "Thursday" => [], "Tuesday" => [], "Wednesday" => []}
在HTML中显示它的最佳方式是什么？
答案 0 :(得分：10)
你无法直接输出这样的地图;只有实现Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
DateTime currentCultureDate = DateTime.Now;
string format = "dd.MM.yyyy HH:mm:ss";
Console.WriteLine("Format: " + format);
Console.WriteLine("Original Date: " + currentCultureDate);
DateTime convertedDate = DateTime.ParseExact(currentCultureDate.ToString(), format, new CultureInfo("de-DE"));
Console.WriteLine("Converted Date: " + convertedDate);
协议的东西。如果要打印Phoenix.HTML.Safe将打印的内容（如果可能，则为Elixir语法），您可以显式调用iex将Map转换为字符串，然后输出：
inspect如果您想以不同的方式打印，可以使用<p>Schedule: <%= inspect @schedule %></p>
