Rails - Feb 2009 - Displaying line breaks & paragraphs using 'simple_format' ?

Hi there,

I need to:

1. STORE a text of the below format in a (MySQL) database (using a
''textarea''), and then
2. RETRIEVE & DISPLAY it in exactly the same format (meaning: keeping
all paragraphs/line breaks).

The intended text format looks like this:

***
Blah blahblah blah blah blahblah blah blah
blahblah blah blah blahblah blah, blah
blahblah.          <- NEW PARAGRAPH

Blah blahblah blah blah.      <- LINE BREAK
Blah blahblah blah blah blahblah blah blah
blahblah blah blah blahblah blah, blah
blahblah.
***

Until now:
- the text is stored in exactly this format in a ''text'' field
in the
database (which I believe is the correct way to do it)
- I have used ''simple_format''
(http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#M001719)
for displaying

The problem is: LINE BREAKS are displayed correctly, but NOT the
PARAGRAPHS (they appear like simple line breaks).

What am I doing wrong ?!

Thanks a bunch for any hints and help !
Tom

Hey Tom-

sadly I noticed this same issue with simple_format

I get around it by adding a model method to whatever the class is with
the text.
For example, if I have pages, and each page has a body, I''ll add a
method like so:

class Page
  def format_breaks
    body.gsub("\n", "<br />")
  end
end

and then call @page.body.format_breaks in the view.

This might lead to performance issues if you have an awful lot of text
though so it might be more efficient to create an after_save callback
instead.

Something like:

class Page
  after_save :format_breaks
  def format_breaks
     update_attribute :body, body.gsub("\n", "<br />")
  end
end

This will update the entry in the database after you save so all you
have to call in the view is <%= @page.body %>

Note - to keep your XHTML valid, you''ll need to wrap the whole thing
in paragraph tags (I believe?)

<p>
  <%= @page.body %>
</p>

Hope that helps?
