    <p>I am using AuthLogic and the subdomain method that dhh covered in <a href="http://37signals.com/svn/posts/1512-how-to-do-basecamp-style-subdomains-in-rails" rel="nofollow noreferrer">this blog post</a>, everything is working great, and as expected. What I'm trying to figure out is how to create a subdomain like 'admin' or 'host' that will have a user authenticated from AuthLogic (this may be trivial and unnecessary to mention) that will manage the subdomains. So basically, all subdomains will act normally, except admin.site.com which will go to its own controller and layout..</p> <p>dhh suggested just throwing in an exception to redirect, but I'm not sure where that goes, it didnt seem that simple to me, any ideas?</p> <p><strong>EDIT</strong> I think that the fact I am using AuthLogic is important here, because the subdomain logic isnt forwarding users anywhere, once authenticated AuthLogic sends the user to /account - so my question may be related to how do I tell AuthLogic to a different spot if the user is a root user, logging into the admin subdomain..</p> <p>Here is the code we have implemented thus far</p> <blockquote> <p><strong>Company Model</strong></p> </blockquote> <pre><code>class Company &lt; ActiveRecord::Base has_many :users has_many :brands, :dependent =&gt; :destroy validates_presence_of :name, :phone, :subdomain validates_format_of :subdomain, :with =&gt; /^[A-Za-z0-9-]+$/, :message =&gt; 'The subdomain can only contain alphanumeric characters and dashes.', :allow_blank =&gt; true validates_uniqueness_of :subdomain, :case_sensitive =&gt; false validates_exclusion_of :format, :in =&gt; %w( support blog billing help api www host admin manage ryan jeff allie), :message =&gt; "Subdomain {{value}} is not allowed." before_validation :downcase_subdomain protected def downcase_subdomain self.subdomain.downcase! if attribute_present?("subdomain") end end </code></pre> <blockquote> <p><strong>SubdomainCompanies Module</strong></p> </blockquote> <pre><code>module SubdomainCompanies def self.included( controller ) controller.helper_method(:company_domain, :company_subdomain, :company_url, :company_account, :default_company_subdomain, :default_company_url) end protected # TODO: need to handle www as well def default_company_subdomain '' end def company_url( company_subdomain = default_company_subdomain, use_ssl = request.ssl? ) http_protocol(use_ssl) + company_host(company_subdomain) end def company_host( subdomain ) company_host = '' company_host &lt;&lt; subdomain + '.' company_host &lt;&lt; company_domain end def company_domain company_domain = '' company_domain &lt;&lt; request.domain + request.port_string end def company_subdomain request.subdomains.first || '' end def default_company_url( use_ssl = request.ssl? ) http_protocol(use_ssl) + company_domain end def current_company Company.find_by_subdomain(company_subdomain) end def http_protocol( use_ssl = request.ssl? ) (use_ssl ?

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).
