link_to (ActionView::Helpers::UrlHelper)

UrlHelper#link_to - HTML5 data- attributes using RESTful approach #rails

Creates a link tag of the given name using a URL created by the set of options . See the valid options in the documentation for url_for . It’s also possible to pass a String instead of an options hash, which generates a link tag that uses the value of the String as the href for the link. Using a :back Symbol instead of an options hash will generate a link to the referrer (a JavaScript back link will be used in place of a referrer if none exists). If nil is passed as the name the value of the link itself will become the name.
