Ruby Ruby Booleans Build a Simple Todo List Program Returning Boolean Values: Part 2

Include? method works in Workspaces but not in Challenge

I used the include method to return whether or not the name variable is in the @todo_items array. It works when I call it in workspaces. It does not work in the challenge. Why is this? The two lines I wrote are below:

var = @todo_items.include?(name)

return var

I had a similar problem on the previous challenge and I don't understand why neither worked. I want to make there's not something I'm misunderstanding.

todo_list.rb 
class TodoList
  attr_reader :name, :todo_items

  def initialize(name)
    @name = name
    @todo_items = []
  end

  def add_item(name)
    todo_items.push(TodoItem.new(name))
  end

  def contains?(name)
    var = @todo_items.include?(name)
    return var
  end

  def find_index(name)
    index = 0
    found = false
        todo_items.each do |item|
      found = true if item.name == name
      break if found
      index += 1
    end
    if found
      return index
    else
      return nil
    end
  end
end

You have to take a closer look at the available code. You may want to use the find_index method. It returns either a number (if that item is found - numbers are "truthy" values) or nil (which is a "falsy" value) if it can't be found. Based on that you can return true or false from the method.
