@user.update_attributes(order_params)

  def order_params
  params.require(:user).permit( order_attributes: [:track_number])
end 

end




class User < ActiveRecord::Base

  has_many :orders

end

You can use this gem strong parameter in rails 3

Link: strong parameter gem.

and If you do not want to add separate gem for this you can allow the parameter by attr_accessible. (This is default and ideal way of allowing parameters).

Ref: attr_accessible document

Edit: To allow nested attributes in attr_accessible you have to use this accepts_nested_attributes_for
