POHow can I tell Rails/HAML to not escape a URL?
text
Body
copied!<p>I have this code: </p> <pre><code>= link_to "unsubscribe instantly", "*|UNSUB|*".html_safe </code></pre> <p>That generates this HTML:</p> <pre><code><a href="*%7CUNSUB%7C*">unsubscribe instantly</a> </code></pre> <p>The | characters are escaped. That won't work, as I'm sending this HTML to a service that is supposed to replace <code>*|UNSUB|*</code> with an unsubscribe url.</p> <p>Instead, I want Rails/HAML to generate this:</p> <pre><code><a href="*|UNSUB|*">unsubscribe instantly</a> </code></pre> <hr> <p>I went to <a href="http://haml-lang.com/try.html" rel="nofollow noreferrer">http://haml-lang.com/try.html</a> and entered <code>%a{:href => "*|UNSUB|*"} unsubscribe</code> and the output was what I was expecting. So I'm guessing this is a Rails thing.</p> <hr> <p><b>UPDATE</b>: I tried this on a new Rails 3.1 application and the pipes aren't being escaped -- which is what I wanted. There's something weird happening with my main rails application that's causing the URLs to be escaped -- looking into it further now.</p> <p><hr> <b>UPDATE</b>: I figured it out. I had some Rack middleware that was running something like:</p> <pre><code>content = Nokogiri(response) # ... processing return content.to_html </code></pre> <p>This was encoding the stuff inside the URLs. I asked a related question here: <a href="https://stackoverflow.com/questions/8512972/preventing-nokogiri-from-escaping-characters-in-urls">Preventing Nokogiri from escaping characters in URLs</a></p>
