Preserve newline in text area with Ruby on Rails

Question

To practice Ruby on Rails, I am creating a blog which includes a text area (following Mackenzie Child\'s tutorial). When the text is submitted, all of the newlines are remov

Answer 1

Newlines are actually being preserved(as \r\n), you just don't see them in your index/show views.

In these views, call simple_format on your post.body field to replace \ns with
s(HTML newlines):

simple_format(post.body)

From docs:

simple_format(text, html_options = {}, options = {}) public

Returns text transformed into HTML using simple formatting rules.
Two or more consecutive newlines(\n\n) are considered as a paragraph and wrapped 
in 
 tags. One newline (\n) is considered as a linebreak and a 
 tag is 
appended. This method does not remove the newlines from the text.
