Question

所以我试图创建一个由多个类组成的数组，我称之为Homes

但是当我运行我的代码时，我的数组只包含一个Home 我在Rails框架中这样做。

class HomesController < ApplicationController

    def index
        home_names_array = ['Kodu 1' 'Kodu 2']
        homes = []

        home_names_array.each do |home|
            x = Homes.new
            x.home_name = home
            x.create_apartments(['Korter 56', 'Korter 78'])
            homes << x
        end

        homes.each do |x|
            logger.debug homes.size
            logger.debug "Home name: #{x.get_name}\n"
        end
    end

    class Home
        attr_accessor :home_name
        APARTMENTS = []

        def create_apartments(apartment_names)
            apartment_names.each do |apartment|
                x = Apartment.new
                x.apartment_name = apartment
                APARTMENTS << x
            end
        end

        def get_name
            home_name
        end

        def get_apartments
            APARTMENTS.each do |apartment|
                apartment
            end
        end
    end

    class Apartment
        attr_accessor :apartment_name

        def get_apartment_name
            apartment_name
        end
    end

end

在索引操作中，它应该将x这是一个类推送到我的数组。但结果只是一个变量，其中包含一个类。

您在home_names_array中遗漏了逗号。它应该是home_names_array = ['Kodu 1', 'Kodu 2']

无法在Ruby中创建一个Classes数组
