Challenge Task 1 of 1

Fill in the find_index method to return the index of a todo item in the @todo_items array given the name. The method should return the index of the item if the item is found and nil if it is not found.

Bummer! The find_index method did not return the correct index.

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 find_index(name)
    index = 0
    found = false
    if found
      return index
    else
      return nil
    end
  end

end

Almost, but you need to add an each method before returning the value to loop through the array to see if the name value matches the name value in the array:

   def find_index(name)
    index = 0
    found = false

    todo_items.each do |todo_item| #add each method to loop through array
        if todo_item.name == name
            found = true
            break;
        end
        index += 1
    end

    if found
        return index
    else
        return nil
    end
  end

hope that helps!!
