The only reason this may appear to work is that ActiveRecord takes control of the initialize method.

So, when you use ActiveRecord, you can't use initialize -- you have to use other weird methods.

tl;dr -- ActiveRecord will handle the assignments when you do automobile = {color: "Black", make: "SUV", model: "Range Rover", year: 2013}

@make = make
@model = model
@year = year
end

def number_of_tires
4
end
end

automobile = {color: "Black", make: "SUV", model: "Range Rover", year: 2013}
puts automobile

class Vehicle < Automobile
@@count = Vehicle.count

OK, so you're not sure. If I needed Hondas (in active record), I would

Automobile.where(make: "honda")

And if I needed blue cars:

Automobile.where(color: "blue")

And you can combine them:

Automobile.where(make: "honda").where(color: "blue")

end
end

This is not an assertion, it's an assignment. If you wanted to run a test:

Automobile.number_of_times.should eq(4)

end
end

describe Vehicle do
it "should have a count" do
#not sure what to do here
end
end

describe Motorcycle do
it "should have two tires" do
number_of_tires == 2
