Ruby on Rails 301 redirection

Question

I added slugs to some of the models, but because of SEO I need to do 301 redirection from old links: old:

http://host.com/foo/1

new:

Answer 1

For 301 redirection write this code in your controller:

headers["Status"] = "301 Moved Permanently"

redirect_to "http://host.com/foo/foo_slug" # in your case

And for second question, use capitalise or down case if you mentioned hardcode url.

Otherwise use ruby interpolation by putting whole url in string
