Not rendered recaptcha in rails 3

Question

Use of rails 3 recaptcha. In view _form.html.erb insert <%= recaptcha_tags %> But when viewing the page in the browser receives

<script type="text/javascript" src="http://api.recaptcha.net/challenge?k=**&error=expression"></script>

As I understand it is not rendered in the browser. Why '<' instead of < ?

Answer 1

Try <%= raw recaptcha_tags %>. Or use html_safe inside helper. Explanation here: http://asciicasts.com/episodes/204-xss-protection-in-rails-3
