Question

I was looking at example code from the O’Reilly book on Ruby on Rails and ran across this:

 def label_for(method, options={})
    extra = ""
    if options[:required]
      extra = " <span class='required_mark'>*</span>"
    end
    label(:label || method) + extra + "<br />"
  end

I understand that options is a hash, but how is it able to call label with just :label — shouldn’t it need to say options[:label] ?

Thanks!

Yes, I believe so, otherwise the :label symbol will always be passed as a method name to label helper.
