How to Show Most Recent Article in Rails app in another view

In my Rails Blog app I have my welcome controller and view index.html.erb. And I have my articles controller and views index.html.erb and show.html.erb.

My articles view has two views, one for listing articles index.html.erb, and the other for showing articles show.html.erb. When listing articles in my articles view everything works perfectly. But my goal is to list the most recent article in a popup modal in my welcome view index.html.erb.

Below is the code for listing articles in the articles view

<% @articles.reverse.each do |article| %>
                <div class="w3-quarter">
                    <div class="panel panel-default" style="width: 300px; min-height: 300px;">
                      <div class="panel-heading">
                          <h3><%= article.title %></h3>
                          <p class="w3-opacity"><%= article.created_at.strftime("%b %d, %Y") %>  |  Comments <span class="label label-primary"><%= article.comments.count %></span> </p>
                      </div>
                      <div class="panel-body">
                          <p><%= article.text.first(250) %> ...</p>
                          <%= link_to 'Read More', article_path(article), class: 'btn btn-primary btn-block' %>
                      </div>
                    </div>
                </div>
            <% end %>

And below is the code for listing the most recent article in my welcome view

<!-- Modal -->
        <div id="myModal" class="modal fade" role="dialog">
          <div class="modal-dialog">

            <!-- Modal content-->
            <div class="modal-content">
              <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Modal Header</h4>
              </div>
              <div class="modal-body">
                  <h2><%= @article.title %></h2>
                  <p class="w3-opacity">Posted on <%= @article.created_at.strftime("%b %d, %Y") %></p>
                  <hr>
                  <p><%= @article.text.first(500) %></p>
              </div>
            </div>

          </div>
        </div>

I get the following error from my welcome index.html.erb:

undefined method `title' for nil:NilClass

Any ideas?

Probably you are not setting @article in you welcome_controller

Try something this

class WeclomeController < ApplicationController

  def index
    @artice = Article.order(created_at: :desc).first
  end

end
