Ruby - html tags are not converted to formatting tags

Question

I have a simple form, where a user can write some text and this text will be send to his email. This process works fine, but I have a problem with the text, that user wrote - in the email is displayed following:

["sadgsdah\r\nsdh\r\ndsf\r\nh\r\nfdhdfhdfh\r\n\r\n\r\n\r\nfdh\r\ndf\r\njh"]

why there are the brackets and the \n and \r chars?

Before than I give the variable with the content into the email template, I tried to do following:

mess_body = params[:contact][:message].to_s.html_safe

But unfortunately this didn't help me... what I am doing wrong?

To convert newlines to look right in html, use simple_format to convert the text.

First of all

mess_body = params[:contact][:message]

returns a array, not a single thing. That is why you get the [" and "] around the output. you could get the first element like this:

mess_body = params[:contact][:message][0]

Furthermore \n\r are line endings of a text box. Assuming that the e-mail you're sending is HTML the \n\r should be replaced by <br> in the String

yes, I totally forgot for that array instead of string. But still have the problem about \n\r - they're just replaced by the white space, not by the new line - this is how I see that in the mailbox. But when I take a look at the log of the project, there are correctly displayed new line tags...

If the text is going into an html message, newlines are converted are just spaces visually - to make html force a newline, you need a <BR> tag

@DGM you mean I have to manually convert \n\r chars to <br />?

Yes That is what you should do

yes, but don't reinvent it, use the rails helper I posted in another answer.
