url_for(url_fragment, mode=:path_only)
click to toggle source
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"
