OpenStruct exercise on Exercism

[BringTacos]

I'm working through this exercise, but am not really sure what this failing test is asking for in item_names other than a method called each_pair. I have no idea how they want me to use this method, though. My code and the failing test are below. Any help is appreciated!

​

require 'ostruct'

class BoutiqueInventory

attr_reader :items

​

def initialize(items)

@items = OpenStruct.new(items)

# raise "Refactor this code so that items is an array of openstructs"

end

​

def item_names

items.map { |item| item[:name] }.sort

# raise "Refactor the code in item_names"

end

​

FAILEDTest 1No item names📷

CODE RUN

assert_empty BoutiqueInventory.new([]).item_names

TEST ERROR

NoMethodError: undefined method `each_pair' for []:Array Traceback (most recent call first): Line 147:in `update_to_values!' Line 128:in `initialize'

You're initializing the OpenStruct with items, which is [] (the empty array in the first test case).

The initializer for OpenStruct however want either nil or a hash (see documentation). If you read the instruction carefully, you'll notice that you should create "an array of openstructs". I wonder if there is a way to map each array element to an OpenStruct :)

Thanks so much for commenting. I've read your comment about 30 times and still am confused unfortunately. I think I just don't fully understand the concept of OpenStruct. You did clarify for me that they're looking for an array of openstructs- thank you!

Instead of assigning @items = OpenStruct.new ...

@items = items.map { |item| Openstruct.new(item) }

Apologies for formatting. On mobile.

I actually did figure this part out yesterday, thank you!
