How to display a string the way it was entered ( w return new line)

On input in a text area, the user can se the return key which generate a \r\n inside the string the address is stored per se the way it was keyed in ..

@partner[:bank_location] => "92, Place Honoré d'Urfé\r\n35140, La Chapelle-Saint-Aubert"

When displaying it inside a table cell, the \r\n is ignored , and the generated html is :                          <tr>                           <td colspan="2">Adresse</td>                           <td colspan="2">                             92, Place Honoré d'Urfé                             35140, La Chapelle-Saint-Aubert                           </td>                         </tr> but it's not displayed like that ... I rather get :                Adresse 92, Place Honoré d'Urfé 35140, La Chapelle- Saint-Aubert

Is there a way to modify this behavior or should I gsub the string to insert html <br> tags ??

thanks for feedback

No, there is no way to modify "this behavior" of how the HTML standard treats, and has always since day 1 treated, whitespace.

a \r\n inside the string

@partner[:bank_location]

=> “92, Place Honoré d’Urfé\r\n35140, La Chapelle-Saint-Aubert”

When displaying it inside a table cell, the \r\n is ignored , and the

generated html is :

                     <tr>

                      <td colspan="2">Adresse</td>

                      <td colspan="2">

                        92, Place Honoré d'Urfé

                        35140, La Chapelle-Saint-Aubert

                      </td>

                    </tr>

but it’s not displayed like that …

I rather get :

           Adresse  92, Place Honoré d'Urfé 35140, La Chapelle-

Saint-Aubert

insert html
tags ??

I’ve always used gsub. I normally have a function called nl2br that’s just gsub(“\n”, ‘
’) . In my views I just call = nl2br(address)

OK thanks , thats' what I thought initially... as you defined a function .. and I'll define a function .. and many others have done before us .. this could have been defined in the core String class...

I just went to write this and discovered there’s a helper called simple_format that does exactly the same thing.
