Hey @waissbluth - are you including this partial into your layout?

Could you share your url_for helper method.

Thanks

@joshforeman, it's several months since you asked this, but maybe still of interest: this belongs into the <head>...</head> section of your site. I'd suggest not subtracting [I18n.locale] though because per Google's definition, the current page needs to link back to itself:

If you have multiple language versions of a URL, each language page should identify different language versions, including itself.

In addition, you may want to add only_path: false in order to get absolute URLs:

-# For each locale except the current one
- I18n.available_locales.each do |locale|
  -# Add a link to the current URL but in `locale` language
  %link{rel: 'alternate', hreflang: locale, href: url_for(locale: locale, only_path: false)}

url_for is a Rails method.

I use the above code with a Rails 5.1.0 application.

You also should add x-default to get default page when there won't any matched page.

- # It will be taken when no one of the available_locales will be relevant.

%link{rel: 'alternate', hreflang: 'x-default', href: url}
- I18n.available_locales.each do |locale|
  %link{rel: 'alternate', hreflang: locale, href: url_for(locale: locale, only_path: false)}
