ActionController::Head

Public Instance Methods

head(status, options = {}) click to toggle source

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?
render
# File lib/action_controller/metal/head.rb, line 17
def head(status, options = {})
  options, status = status, nil if status.is_a?(Hash)
  status ||= options.delete(:status) || :ok
  location = options.delete(:location)

  options.each do |key, value|
    headers[key.to_s.dasherize.split('-').each { |v| v[0] = v[0].chr.upcase }.join('-')] = value.to_s
  end

  self.status = status
  self.location = url_for(location) if location
  self.content_type = Mime[formats.first] if formats
  self.response_body = " "
end
