Is find() a class method or instance method?

Rails
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)?

No, because although it is a public instance method, it’s a public
instance
method of ActiveRecord::Relation, not of ActiveRecord::Base.
ActiveRecord
delegates the find method (and the other querying type methods such as
where, first, all etc.) to an instance of this
