    <p>I am currently following the <a href="http://ruby.railstutorial.org/" rel="nofollow">Ruby on Rails Tutorial by Michael Hartl</a>. And there is something that has been bugging me for quite some time. I looked it up but I still can't find a good answer.</p> <p>Anyway, I've noticed is when you have a validation error in the signup page it renders the original signup page and changes the nav bar address. I've matched <strong>/signup</strong> to the action <strong>new</strong>, but if I use <strong>render</strong> it changes from <strong>/signup</strong> to <strong>/users</strong> (the default, because of the RESTful standard I guess). </p> <p>I'll leave some lines of my code:</p> <p>routes.rb</p> <pre><code> resources :users match '/signup', :to =&gt; 'users#new' </code></pre> <p>users_controller.rb</p> <pre><code> def new @user = User.new @title = "Sign up" end def create @user = User.new(params[:user]) if @user.save sign_in @user flash[:success] = "Welcome to the Sample App!" redirect_to user_path(@user) else @title = "Sign up" @user.password = "" @user.password_confirmation = "" render 'new' end end </code></pre> <p>So I've tried to work around this by not using the <strong>render</strong> method but <strong>redirect_to</strong> instead but I'm having trouble using it. As it is actually sending data to the path provided, @user.errors gets overwritten by creating a new instance of the model and the flash variable cannot show the errors.</p> <p>_errors.html.erb</p> <pre><code>&lt;% if @user.errors.any? %&gt; &lt;div id="error_explanation"&gt; &lt;h2&gt; &lt;%= pluralize(@user.errors.count, "error") %&gt; prohibited the user from being saved: &lt;/h2&gt; &lt;p&gt;There were problems with the following fields:&lt;/p&gt; &lt;ul&gt; &lt;% @user.errors.full_messages.each do |message| %&gt; &lt;li&gt;&lt;%= message %&gt;&lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>My question is: is there any way that by using <strong>render</strong> I can change the url displayed on the navbar? It's really frustrating if someone makes a mistake in the signup form, presses enter in the navbar and ends up in a totally different place.</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
