Ruby on Rails latest stable (v4.1.8) - 2 notes - Class: ActionController::Base

Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v2.3.8) is shown here.

These similar methods exist in v4.1.8:

head(*args) protected

Return a response that has no content (merely headers). The options argument is interpreted to be a hash of header names and values. This allows you to easily return a response that consists only of significant headers:

  head :created, :location => person_path(@person)

It can also be used to return exceptional conditions:

  return head(:method_not_allowed) unless request.post?
  return head(:bad_request) unless valid_request?
