Full URL with url_for in Rails

Question

How can I get a full url in rails?

url_for @book is returning only a path like /book/1 and not www.domain.com/book/1

Thanks (and sorry if the answer is obvio

Answer 1

Use the :host option. For example, you can use:

url_for(@book, :host => "domain.com")

Note: with Rails 3 and above, use polymorphic_url instead of url_for.
