    <p>I am running into routing issues regarding subdomains in Rails 3 when porting from Rails 2.3.x + gem subdomain_routes. With the subdomain_routes gem I was able to map routes easily by model like the following:</p> <pre><code># config/routes.rb map.subdomain :model =&gt; :site do |site| resources :pages end </code></pre> <p>This would generate url helpers, like <code>site_pages_url</code> and could be used like this:</p> <pre><code># console @site = Site.find_by_subdomain(“yehuda”) app.site_pages_url(@site) =&gt; http://yehuda.example.com/pages app.site_page_url(@site, @page) =&gt; http://yehuda.example.com/page/routes-rock </code></pre> <p>In Rails 3 this roughly would translate to:</p> <pre><code># config/routes.rb class SiteSubdomain def self.matches?(request) request.subdomain.present? &amp;&amp; request.subdomain != 'www' &amp;&amp; request.params[:site_id].present? end end Blog::Application.routes.draw do resources :sites do constraints(SiteSubdomain) do resources :pages end end end </code></pre> <p>and overloading the standard url_for should basically work like in subdomain_routes:</p> <pre><code>module UrlFor def with_subdomain(subdomain) subdomain = (subdomain || "") subdomain += "." unless subdomain.empty? [subdomain, request.domain, request.port_string].join end def url_for(options = nil) if options.kind_of?(Hash) &amp;&amp; options.has_key?(:subdomain) options[:host] = with_subdomain(options.delete(:subdomain)) end super end end ActionDispatch::Routing::UrlFor.send(:include, UrlFor) </code></pre> <p>However, the url helpers still do not generate the correct URL like <code>site_pages_url(@site) #=&gt; <a href="http://www.example.com/pages" rel="nofollow">http://www.example.com/pages</a></code>, instead of the expected <code>http://yehuda.example.com/pages</code></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.
