How to get a line break in a plain text email RoR?

问题

I'm sending a plain text email and was wondering how I add a line break to this. It's showing up on on the same line.

From: <%= @name %>
<%= @text %>

Thanks

回答1:

\r\n

or if you're sending html email:

<br />

so:

From: <%= @name %> \r\n <%= @text %>
From: <%= @name %> <br /> <%= @text %>

回答2:

<%= "\r\n" %>

In double quotes and inside '<% %>'.

Otherwise it's considered as simple text.

回答3:

I could be completely wrong, but isn't it a simple \n ?
