Displaying tweets in my view

I'm a Rails noob and I'm following a blog post I found here...

I have everything working up until the end. Then things get nebulous.

So if I have this in my helper...

module ApplicationHelper
  def display_content_with_links(tweet)
    tweet.content.gsub(/(http:\/\/[a-zA-Z0-9\/\.\+\-_:?&=]+)/) {|a| "<a href=\"#{a}\">#{a}</a>"}
  end
end

Shouldn't I be able to have my tweets display in my view with this...

What am I doing wrong?

Actually, you should add

@tweet = Tweet.all

To the controller#action you have setup already, then iterate over them in your view:

<ul>
  <% @tweets.each do |tweet| %>
    <li><%= display_content_with_links tweet %></li>
  <% end %>
</ul>

You are going to need a controller and view to have this display. Something simple like:

# app/controller/tweets_controller.rb
TweetsController < ApplicationController
  def index
      @tweets = Tweet.get_latest
  end
end

and in the view:

# app/views/tweets/index.html.haml
%ul
  - @tweets.each do |tweet|
    %li
      = display_content_with_links tweet

or if you use erb

# app/views/tweets/index.html.erb
<ul>
  <% @tweets.each do |tweet| %>
    <li>
       <%= display_content_with_links tweet %>
    </li>
  <% end %>
</ul>

This is a pretty basic example that might not even come close to what you want, but it should point you in the right direction.
