Hi All, Today, when I debug, I found that I don't understand a very basic function "super".
<code> class User < ActiveRecord::Base def self.columns puts "here....................." @ret = super return @ret end end </code> This return only one line of "here.....................". It is very fine. However, when I called My codes are: <code> class User < ActiveRecord::Base def self.columns puts "here....................." super end end </code> The return is what I expected - a list of columns in User, but this display 18 lines of "here....................." in the console (the length of "columns" of my User is 17. What is the difference between the two super call? Thanks much!
