Ruby - Partial Pages

To link to another page

<%= link_to "Alpha Blog", articles_path %>

Under app/views/layouts folder create a _messages.html.erb file (messages partial) and remove the following code from application.html.erb to this file:

<% flash.each do |name, msg| %>
<ul>
<li><%= msg %></li>
</ul>
<% end %>

In place of this code in the application.html.erb add the following code:

<%= render 'layouts/messages' %>

Create a file under app/views/articles folder called _form_html.erb and fill it in with the following code (copied from the new or edit.html.erb page):

<% if @article.errors.any? %>
<h2>The following errors prevented the article from getting created</h2>
<ul>
<% @article.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
<%= form_for @article do |f| %>
<p>
<%= f.label :title %><br/>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :description %><br/>
<%= f.text_area :description %>
</p>
<p>
<%= f.submit %>
</p>
<% end %>
<%= link_to "Back to articles listing", articles_path %>

Then remove the code above from both new.html.erb and edit.html.erb files and in it's place add the following code:

<%= render 'form' %>
