link_to

link_to is a rails helper that helps generate html link tags in views and controllers. link_to "relies on" (whatever that means) url_for - a similar (but different) helper that generates links in views and controllers. From the [ActionView docs] (http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to):

link_to(name = nil, options = nil, html_options = nil, &block)

Creates a link tag of the given name using a URL created by the set of options.
