why do I keep getting this error: undefined method new_message_path

So I made a quick ruby on rails app (railstutorial twitter clone). My source code is the same as https://github.com/railstutorial/sample_app_2nd_ed.

Then I tried adding replies to the messages with http://railscasts.com/episodes/262-trees-with-ancestry?view=asciicast. My comment is at the bottom BigBoy1337. This is what it says:

I keep getting an error saying

undefined method `new_message_path'

This is in app/views/messages/_messages.html.erb

for

<%= link_to "Reply", new_message_path(:parent_id => message) %> 
<% if current_user?(message.user) %>
<%= link_to "delete", message, method: :delete,
                     confirm: "You sure?",
                     title: message.content %>
<% end %>

Any idea where to define new_message_path? I tried adding

def new_message_path
end

in app/controllers/message/controllers

...but it didn't work. I have downloaded the source code (https://github.com/BigBoy1337/railscasts-episodes/tree/master/episode-262/messenger-after) and that works! but I cant find where they define new_message_path, yet it works. Why does it work for them, and how can I get it to work for me?

new_message_path is defined in routes.rb.

Look for this line:

resources :messages

That's a resource route. Try adding the following to routes.rb:

resources :messages

Also, read this: http://guides.rubyonrails.org/routing.html
