ToDo List


Can anyone please tell why I'm getting the below error on the below code?

"odo_list.rb:62:in <class:TodoList>': undefined methodmark_complete' for #<TodoList:0x005614cf 1eb970> (NoMethodError) from todo_list.rb:3:in `<main>'


    require "./todo_item"

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 remove_item(name) if index = find_index(name) todo_items.delete_at(index) return true else return false end

def mark_complete(name) if index = find_index(name) todo_items[index].mark_complete! return true else return false end end end

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

todo_list = TodoList.new("Groceries") todo_list.add_item("Milk") todo_list.add_item("Eggs") todo_list.add_item("Bread")

if todo_list.remove_item("Eggs") puts "Eggs were removed from the list." end

if todo_list.mark_complete("Milk") puts "Milk was marked as complete." end puts todo_list.inspect end

Please format the Markdown so it's readable.

One error I found: use double equal signs


for equalities, not


or else Ruby thinks you are making a variable.
