Remove unexpected content on a website

Question

While following a tutorial on building a Ruby-on-Rails blogging website, I'm running into some unexpected results. The project so far is stored on https://github.com/khpeek/jumpstart-blogger.

The main page is an "Articles" page, which looks like this:

So far, so good (except for the somewhat curious position of the "Create a New Article" button, which used to be directly below the articles).

The appearance of "All Articles" is governed by app/views/articles/index.html.erb, which reads

<h1>All Articles</h1>

<ul id="articles">
  <% @articles.each do |article| %>
    <li>
      <%= link_to article.title, article_path(article), class: 'article_title' %>
    </li>
  <% end %>
</ul>

<%= link_to "Create a New Article", new_article_path, class: "new_article" %>

The h1 heading is the first thing in the .html.erb file, and also the first thing that appears on the web page.

However, if I click on an article link, say "Article with Ruby Tag", I see the page below:

Besides the desired box with the article, tags, and comments, there are also two submit buttons and "<< Back to Articles List" buttons which are neither desired nor expected.

The appearance of this page is governed, as I understand it, by app/views/articles/show.html.erb, which reads

<h1><%= @article.title %></h1>
<p>
  Tags:
  <% @article.tags.each do |tag| %>
    <%= link_to tag.name, tag_path(tag) %>
  <% end %>
</p>
<% if @article.image.exists? %>
  <p><%= image_tag @article.image.url %></p>
<% end %>
<p><%= @article.body %></p>
<h3>Comments (<%= @article.comments.size %>)</h3>
<%= render partial: 'articles/comment', collection: @article.comments %>
<%= render partial: 'comments/form' %>
<%= link_to "<< Back to Articles List", articles_path %>
<% if logged_in? %>
  <%= link_to "delete", article_path(@article), method: :delete, data: {confirm: "Really delete the article?"} %>
  <%= link_to "edit", edit_article_path(@article) %>
<% end %>

The first line in this file is the h1 header, but the 'unexpected' contents seems to come before that. So I'm having trouble seeing where to start to remove this content. Any pointers?

Answer 1

check your application.html.erb in layouts folder.. it is rendering in header on some condition

Answer 2

You're dealing with layout Rails' concept. Read this.

Anyway, you probably have a layout file in app/views/layouts.
