Hi!

I have some questions:

First, for the new Food class, is there any way to create acceptable_food array without specify the name method in each element of the array?

Second, what is the purpose of the FoodBarge task? I don't understand well this task.

And final, why rspec needs require "./zoo"? Why is not enough require zoo? Could we use here require_relative? How?

Hey David --

Yes, so in that case, you might have several Food classes, like so:

class Tacos < Food; end
class Bamboo < Food; end

Then you could just refer to them as Tacos.new everywhere.

For FoodBarge -- It's something that would hand you food if you tell it what type of animal you want to feed. I'll post a video of filling out the extra credit and maybe it'll make more sense then.

For requiring....

• You can't do require zoo because ruby would see zoo as a method and try to execute it.
• You can't do require "zoo" because in ruby 1.9 the current directory is no longer auto-loadable
• You COULD do require_relative "zoo" without issue -- I am going to introduce that later.

Yes, but actually my acceptable_food method for Humans is:

def acceptable_food
  [Food.new(:bacon).name, Food.new(:tacos).name]
end

I had have to add the .name in order to the array works in likes? method? My question was, any way to no repeat name in each item of the array? I mean, is there any way to extracts the name from the likes? method?

Yes, you don't have to refer to it as name ....

def acceptable_food
  [Food.new(:bacon), Food.new(:tacos)]
end

then in your likes you could:

def likes(food)
  acceptable_food.include(food)
end

and in Food:

class Food
  def ==(other)
    name == other.name
  end
end
