Wrong Number of Arguments Error with ActiveRecord New

Question

I have a ActiveRecord::Base subclass. When I create a new instance I'm getting an argument error:

ArgumentError:
       wrong number of arguments (2 for 1)

Here is my code:

class Subclass < ActiveRecord::Base

end

Subclass.new(hash, without_protection: true)

Gem versions are:

activemodel (3.2.13)
activerecord (3.2.13)

Why does this generate and argument error? According to API Dock, inititialize still takes two arguments as of 3.2.13

Can you confirm you are calling it with the parenthesis? `Subclass.new(hash, without_protection: true)` — Jesse Wolgamott, Jul 05 '13 at 15:34
Are you sure the error is cause at `Subclass.new`? It may be occurring at some other place. — sawa, Jul 05 '13 at 15:45
@sawa The code I've posted is what I'm running to generate this error. — Undistraction, Jul 05 '13 at 15:58

Looks like RubyGems is using the incorrect version of ActiveModel. From the error:

/Users/me/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/activerecord-4.0.0/lib/active_record/core.rb:180:in `initialize': wrong number of arguments (2 for 1) (ArgumentError)

No idea why, so posted another question (here)[Rubygems Loading Wrong Version of Gem
