Here’s the code to realise nl2br of PHP in Rails.
Environment
(Unless Rails changes considerably), it can be used in most versions.
- Rails 4.2.5
- Ruby 2.0.0
Method 1: User Prepared Function

Method 2: Create Custom Function
For example, create the function nl2br at ApplicationHelper like the following.
It doesn’t realize all of nl2br in PHP but it convert LF to <br>. We can use it as the following.
