    <p>I'm trying to create a registration form with Rails. It's working, but it doesn't displays the errors from the validation (it validates, but the errors don't display).</p> <p>Here are my files:</p> <pre><code># new.html.erb &lt;h1&gt;New user&lt;/h1&gt; &lt;% form_for :user, :url =&gt;{:action=&gt;"new", :controller=&gt;"users"} do |f| %&gt; &lt;%= f.error_messages %&gt; &lt;p&gt; &lt;%= f.label :name %&gt;&lt;br /&gt; &lt;%= f.text_field :name %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.label :password %&gt;&lt;br /&gt; &lt;%= f.password_field :password %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.submit 'Create' %&gt; &lt;/p&gt; &lt;% end %&gt; &lt;%= link_to 'Back', users_path %&gt; </code></pre> <hr> <pre><code># user.rb class User &lt; ActiveRecord::Base validates_presence_of :name validates_presence_of :password end </code></pre> <hr> <pre><code>#users_controller.rb class UsersController &lt; ApplicationController def index @users = User.all end def show @user = User.find(params[:id]) end def new if session[:user_id].nil? if params[:user].nil? #User hasn't filled the form @user = User.new else #User has filled the form user = User.new(params[:user]) if user.save user.salt = rand(1000000000) user.password = Digest::MD5.hexdigest(user.salt.to_s + user.password) user.save flash[:notice] = 'User was successfully created.' session[:user_id] = user.id session[:password] = user.password redirect_to url_for(:action=&gt;"index",:controller=&gt;"users") else render :action=&gt;"new" end end else #User is already logged in flash[:notice] = 'You are already registered.' redirect_to url_for(:action=&gt;"index") end end # some other actions removed.... end </code></pre> <hr> <p>Why aren't the errors being displayed?</p> <p>Thanks!!</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.

SQuiL has stopped working due to an internal error.

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