Ruby - redirect_to redirects to the correct page, but isn't changing the URL
<p>I am teaching myself Ruby and Rails...  and until today, have been feeling pretty good about it.  :)  </p>

<p>However, today I ran into an issue I can't seem to crack.  I am practicing by creating a blog.  I have the routes and views set up - and the code will write to the database - but the redirect_to doesn't seem to be working properly.</p>

<p>If the user navigates to: .../article/new, they can enter a new article.  Upon successful submission, the app should redirect to the URL ../article/id, display the article on show.html.erb and flash a message that the article saved successfully.</p>

<p>For some reason, I cannot get the URL redirect portion to work.  The article saves, the show.html.erb displays with the proper message...  but the url stays ../article/new.  If the redirect doesn't work, the rest of the application won't work because other actions require different URLs (../article/id/edit, for example).</p>

<p>I have been using <pre>&lt;%= @article.inspect %></pre> on the show page and it looks like everything has saved correctly (which I suspected because it calls the correct view).</p>

<p>Any thoughts would be very, very welcome.  I'm really excited to be learning Ruby and Rails and look forward to getting through this.</p>

<p>articles_controller.rb:</p>

<pre><code>class ArticlesController &lt; ApplicationController
  def new
    @article = Article.new
  end

  def create
    @article = Article.new(article_params)
    if @article.save
      flash[:notice] = "Article was successfully created"
      redirect_to article_path(@article)
    else
      render 'new'
    end
  end

  def show
    @article = Article.find(params[:id])
  end

  private
  def article_params
    params.require(:article).permit(:title, :description)
  end
end
</code></pre>

<p>rake routes:</p>

<pre><code>Prefix Verb   URI Pattern                  Controller#Action

             DELETE /articles/:id(.:format)      articles#destroy
