Ruby on Rails seems to be auto-escaping html created by link_to

Question

Here is my code, I\'m trying to display a list of links to a bboy\'s crews in sentence form with .to_sentence

    <% if         


        

Answer 1

Rails 3 now automatically escapes everything, in order to output raw HTML use this:

<%= some_string.html_safe %>

or this:

<%= raw @some_html_string %>

Thanks to macek for a hint.

Answer 2

You can (and should) you the raw method

<%= raw @some_html_string %>

Answer 3

I recommend you move this block of code to an helper and then use the .html_safe method to obtain the expected results.

Answer 4

I agree with Kleber S, you should move this into a helper, because that's a lot of logic for a view

def crews_description(crews)
  if crews.empty?
    content_tag('em', 'Independent')
  else
    label = "Crew"
    label = label.pluralize if crews.size > 1
    crews_links = crews.map {|crew| link_to(h(crew.name), crew)}.to_sentence
    content_tag('span', label) + crews_links.html_safe
  end
end

and in your view:

<span class="affiliation">
  <%= crews_description(@bboy.crews)
</span>
