You forgot to pass article_params to update. 

def update
    @article = Article.find(params[:id])
    if @article.update(article_params)
      flash[:notice] = 'Article was successfully updated'
      redirect_to article_path(@article)
    else
      redirect 'edit'
    end
  end

Yip, as Alfie said above, you're missing your article_params. In rails 4 (which I assume is what you're using) there is the concept of strong paramaters, which is a way of only allowing the fields you're expecting through.

Depending on what fields are in your "article" object, you need to add something like this:

  def article_params
    params.require(:article).permit(:title, :body)
  end

Note, you'll need to adjust it to suit whatever your actual fields are.

Also, might be a copy & paste error, but it's a good idea to get into the habit of indenting your code correctly! Good luck with getting the codes to work :)

You need to define your article_params in your controller
