using linebreak in action mailer on the @body-CodePudding

i have build some website that take a message and send it to email recipient, the user can send emails by typing the message and the recipient. my issue is when a user type : "My \r\n name \r\n is \n user" the emails that have been sent is ignoring the linebreaks, or any html code inside the message, how can i support it ?

this is the html that have been sent:

    <!DOCTYPE html>
<html>
  <head>
    <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
  </head>
  <body >
    <h3>Hi <%= @user.username %>,</h3>
    
      <%= @message %>


    
  </body>
</html>

CodePudding user response：

Using simple_format did the trick

<!DOCTYPE html>
<html>
  <head>
    <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
  </head>
  <body >
    <h3>Hi <%= @user.username %>,</h3>
    
      <%= simple_format(@message) %>


    
  </body>
</html>
