title: Parameter missing in rails controller which is not missing
body: <p>I have been recently learning ruby and rails in order to build a web application, so I have been following the starting out guide on the rails website.</p>
  
  <p>I have got to a point where I am attempting to submit a form to my database, and rails is throwing this error:</p>
  
  <p>ActionController::ParameterMissing in ArticlesController#create
  param is missing or the value is empty: aritcle</p>
  
  <p>Here is the code that it is refering to:</p>
  
  <pre><code>class ArticlesController &lt; ApplicationController
  def new
  end
  
  private
  def article_params
      params.require(:aritcle).permit(:title, :text)
  end
  
  public
  def create
      @article = Article.new(article_params)
  
      @article.save
      redirect_to @article
  end
  </code></pre>
  
  <p>end</p>
  
  <p>What is interesting about this is that I had the code working ten minutes ago, exactly the same as it is now, but when I tried to tidy it up, it started throwing this error again, and when I put it back this way it didn't stop.</p>
  
  <p>I have not seen this elsewhere, so would really appreciate any help with this.</p>
  
  <p>Thanks.</p>
