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 “example.com/myapp/foo” – See README.rdoc for a list of some of the people who helped me clean up earlier versions of this code.
