v2.1.0 - Show latest stable - 0 notes - Class: ActionController::UrlWriter
url_for(options) public

Generate a url based on the options provided, default_url_options and the routes defined in routes.rb. The following options are supported:

  • :only_path - If true, the relative url is returned. Defaults to false.
  • :protocol - The protocol to connect to. Defaults to ‘http’.
  • :host - Specifies the host the link should be targetted at. If :only_path is false, this option must be provided either explicitly, or via default_url_options.
  • :port - Optionally specify the port to connect to.
  • :anchor - An anchor name to be appended to the path.
  • :skip_relative_url_root - If true, the url is not constructed using the relative_url_root set in ActionController::AbstractRequest.relative_url_root.
  • :trailing_slash - If true, adds a trailing slash, as in "/archive/2009/"

Any other key (:controller, :action, etc.) given to url_for is forwarded to the Routes module.
