I have read <ul> <li><a href="https://stackoverflow.com/questions/975877/how-to-give-cname-forward-support-to-saas-">How to give cname forward support to saas software</a></li> <li><a href="https://stackoverflow.com/questions/377137/rails-multiple-top-level-domains-and-a-single-session-cookie">Rails - Multiple top level domains and a single session/cookie</a></li> </ul> But I am unable to get a solution for the following setup: <ul> <li>A SaaS Webapp in Rails is running under example.com</li> <li>All users have a sumbdomain e.g. user1.example.com</li> <li>Users can create a cname forwarding eg. exampleapp.user1.com -> user1.example.com</li> </ul> It is all working until a user tries to log in via exampleapp.user1.com. The SaaS app fails to set the session domain right, because it is configured static on app startup. <pre><code>config.action_controller.session = { :session_key => '_example_session', :domain => ".example.com", :secret => 'abc' } </code></pre> The Request fails with a <code>ActionController::InvalidAuthenticityToken</code>. And that is correct, because the domain changed from <code>.example.com</code> to <code>exampleapp.user1.com</code>. How do I change the domain config during runtime? I know that the "incoming" domain <code>exampleapp.user1.com</code> belongs to <code>user1</code>, so I want to do something like that in the controller: <pre><code>session :domain => 'exampleapp.user1.com' </code></pre> Or can I always set the session domain on the current request domain? I know that it's possible somehow, because some apps provide that functionality. Thanks in advance!

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.
