How instance method is called

Ruby
1

Dear friends,

I came across this code snippet from my reading:

require 'active_record'

class Order < ActiveRecord::Base
end

order = Order.find(1)
...

Looking at: http://api.rubyonrails.org/ and search for find(), find() is
an instance public method. So why can we call Order.find(1) here?
Shouldn’t it be Order.new.find(1)?

it should Syntactic sugar,I dont know

This is an excellent question to pose to a rails-focused
audience. ‘find’ is obviously a class method, but maybe they use
special terminology in rails-land…

Dear Warren,

IMHO, It probably “extended” (not “included”) that particular Module
that defines the #find method.

Dear Abinoam,

I think this is the only explanation for this behavior. Thanks.
