    <p>I have a blog in my website where only authenticated users can post. If an existing user that is not yet authenticated is typing a comment when he hits "create" he wil be redirected to the login view to authenticate and then redirected to the articles view. I would like to improve the functionality of my blog by rendering the view where the user was creating the comment so that he doesn't have to type in his comment again.</p> <p>I am rather new to programming and to ruby so I am not sure how to approach this problem. Any suggestions are welcomed. Thank you in advance.</p> <p>My website can be found at <a href="https://github.com/MariusLucianPop/mariuslp-" rel="nofollow">https://github.com/MariusLucianPop/mariuslp-</a> </p> <p>Bellow are what I think are the important parts of the code. Let me know if you would like me to update anything. </p> <p><strong>comments_controller.rb</strong></p> <pre><code>before_filter :confirm_logged_in, :only =&gt; [:create] def create article_id = params[:comment].delete(:article_id) @comment = Comment.new(params[:comment]) @comment.article_id = article_id @comment.posted_by = session[:username] @article = Article.find(article_id) if @comment.save redirect_to article_path(@article) else render "articles/show" end end protected def confirm_logged_in unless session[:user_id] flash[:notice]="Please login before posting a comment." redirect_to login_path return false else return true end end </code></pre> <p><strong>visitors_controller.rb</strong></p> <pre><code>def login #atempting to log in authenticated_user = Visitor.authenticate(params[:username],params[:password]) if authenticated_user session[:user_id]=authenticated_user.id session[:username]=authenticated_user.username flash[:notice] = "You are now logged in." redirect_to articles_path end else if !params[:username].blank? # only rendering the notice if the user tried to login at least once flash[:notice] = "Invalid username/password combination.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
