You -could- make your life a ton easier and set a class variable with 
the total count of created objects. Then you just refer to that variable 
and increment by one - bingo, new id. That's neither here nor there, 
though.

"return parking_spot_number" and "start_point" do the same thing in 
Ruby.

I don't understand how you're calling that function.
Replace it with a dummy function like:

def dummy
  return "It's alive!"
end

And check to see if Javascript properly gets "It's alive!" or not.
