Rails 3 i18n how to *not* escape newlines

Question

I'm using i18n in my .text.haml mailer templates and I want to have a string in en.yml that has a newline but t() is always escaping them even if I use html_safe or suffix the key name with _html.

Is there a way to do this??

p3_html: >
    You love monkeys:
     \n- You look like one
     \n- Your smell like one
     \n- Your account has been flagged

In my html.haml template:

!= t('emails.post.twitter_forbidden.p3_html').html_safe

No matter what the \n are escaped. I can't use %br or anything else because these are text templates. I know I could split this into 4 i18n strings but that would be really sad.

BTW, I checked and it is i18n escaping, not haml.

Answer 1

You could do something like this:

t('emails.post.twitter_forbidden.p3_html').html_safe.gsub("\n", '<br/>')

As far as I know, this is the only way.

Edit

Actually, after some digging, I found the simple_format helper.

Couple of options here: As mentioned above, simple_format will help. Format your yml file like so:

    p3_html: |
      Some text:
      - Point 1
      - Point 2
      - Point 3

And then use

   =simple_format t(:p3_html)

This will give you something like

    <p>Some text
      <br>
      - Point 1
      <br>
      - Point 2
      <br>
      - Point 3
    </p>

Or if you want each line a new paragraph:

    p3_html: |
      Some text:

      - Point 1

      - Point 2

      - Point 3

Which should give you this:

    <p>Some text</p>
    <p>- Point 1</p>
    <p>- Point 2</p>
    <p>- Point 3</p>

or something like this is more flexible

    <% t(:p3_html).each_line do |line| %>
      <li>= |line|</li>
    <% end %>

Enables you to put in different formatting:

    <li>- Point 1</li>
    <li>- Point 2</li>
    <li>- Point 3</li>

Final option is to use an array in yaml:

      p3_html: 
        - Some text:
        - - Point 1
        - - Point 2
        - - Point 3

    <% t(:p3_html).each do |line| %>
      <p>= |line|</p>
    <% end %>

Possibly cleaner, though I think it will play merry hell with commas, and the advantage to the above version is that you can switch between formats without needing to modify your yaml
