Ruby on Rails

Hi,

I'm new to Rails and going through "Getting Started with Rails" 

I've stuck in step 5.10:

def create

  @article = Article.new(article_params)

  if @article.save

    redirect_to @article

  else

    render 'new'

  end

end

As I understand posting new article with invalid title should invoke else statement and render [/new] with error message

It shows error but throws to [http://localhost:3000/articles], instead of [http://localhost:3000/articles/new]

Is it how it supposed to work? 

Or what am I doing wrong?
