#redirect_back_or_to(options = {}, response_status = {}) ⇒ Object

Redirects the browser to the stored referer. If there’s no stored referer will fallback to the the target specified in options.

Redirecting :back using redirect_to will redirect to the <strong>action</strong> referer, which is the form.

Redirecting with redirect_back_or_to :target will redirect to the <strong>form</strong> referer if possible. this is userful when calling a form from other controller and want to get back to where you came from after the update/create/destroy action.
