如何在元描述中使用®(How do I use ® in meta description)

如何在元描述中使用®(How do I use ® in meta description)

我有一个客户希望他们的元描述包含注册符号，但它给我一个无效的字符错误，并使用® 在说明中不转换为®。 使用ree-1.8.7和rails 3.1.1

一些附加信息，此页面描述作为@page_description保存在控制器中，然后以部分方式引入页面。 错误似乎发生在控制器中，因此我猜测必须有一种使用®符号的红宝石方式。

I've got a client who wants their meta descriptions to include the register symbol, but it gives me an invalid character error, and using ® doesn't translate to a ® in the description. Using ree-1.8.7 and rails 3.1.1

Some additional information, this page description is saved in a controller as @page_description and then brought in on the page in a partial. The error seems to be occurring in the controller, so I'm guessing there must be a ruby way of using the ® symbol.

最满意答案

使用html_safe方法将字符串呈现为html。

试试@page_description.html_safe

编辑1：

® 是html中®的字符实体引用。

默认情况下，Rails不会将字符串呈现为html。

为了覆盖此行为，您需要使用html_safe将字符串呈现为html。

Use html_safe method to render the string as html.

try @page_description.html_safe

Edit 1:

® is the character entity reference for ® in html.

Rails does not render string as html by default.

In order to override this behaviour, you need to use html_safe to render the string as html.
