Instance Method Details
#url_for(url_fragment, mode = :path_only) ⇒ Object
Construct a link to url_fragment
, which should be given relative to the base of this Sinatra app. The mode should be either :path_only
, which will generate an absolute path within the current domain (the default), or :full
, which will include the site name and port number. (The latter is typically necessary for links in RSS feeds.) Example usage:
url_for "/" # Returns "/myapp/"
url_for "/foo" # Returns "/myapp/foo"
url_for "/foo", :full # Returns "http://example.com/myapp/foo"
