使用简单程序将未定义的局部变量错误添加到数组中

class Books
    attr_accessor :name, :book_id
    def initialize(name, book_id)
        @name = name,
        @book_id = book_id
    end
end

class BookCollection
    def intialize
        @book_names = []
    end

    def add_to_books(book_name)
        book_name.push(book_names)
    end
end

book1 = Books.new("catch22", "12345")
book_collection1 = BookCollection.new
book_collection1.add_to_books(book1.name)
puts book_collection1
class Books
    attr_accessor :name, :book_id
