"Contains?" doesn't return boolean value

I know that there is something wrong with my choice in syntax and logic. I'm supposed to define the "contains?" method so that it returns a boolean value if there is an item within the todo_items array, but I can't figure out how. I've watched the video a couple times and this seems somewhat unrelated.

Any advice would be appreciated, thanks!

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)
    if todo_items == name
      return true
    else
      return false
    end
  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

Hi there,

You need to iterate through the array and then check if each item's name property matches the parameter passed into the function:

  def contains?(name)
    todo_items.each do |item| # take each item in turn
      if (item.name == name)  # does item's name match?
        return true
      else
        return false
      end
    end
  end

I hope that makes sense!

Steve.
