    <p>I'm currently testing <code>Ember.Router</code> and I'm wondering how I could restrict access to some specific routes when matching a certain criteria. In my example I'm playing with a checkout process where the billing address must be set before the user can proceed to the billing method and so on (for example: the billing method view needs to know the billing country to provide its allowed payment methods).</p> <p>In my attempt I'm trying to validate the model (serialize : function () or maybe enter : function () ?) and when the given value isn't set, the router should redirect to a previous state (had to do this with a little timeout, otherwise the hash won't get updated correctly).</p> <p>Here's a fiddle with my example code</p> <p><a href="http://jsfiddle.net/mediastuttgart/uMKGt/" rel="nofollow noreferrer">http://jsfiddle.net/mediastuttgart/uMKGt/</a></p> <p><strong>EDIT:</strong></p> <p>Found some words by tom dale, though not related to this question but still a good answer: "The entire point of states is to avoid situations like this ... It is the responsibility of the current state to handle them.".</p> <p>cf. <a href="http://github.com/emberjs/ember.js/issues/745" rel="nofollow noreferrer">http://github.com/emberjs/ember.js/issues/745</a></p> <p>Well this makes sense.</p> <p><strong>EDIT2:</strong></p> <p>Though this makes sense while the location method is set to 'null'. When using 'hash' or 'history' to handle location states and the user reloads the page on a deeper route than /index - the current route must validate the values and then eventually redirect to a previous one if a certain criteria does not match (while indeed the validation belongs to the previous route).</p> <p>To cut a long story short, the current route validation should depend on the previous one and should redirect to a state when all conditions are met.</p> <p>Reverse order:</p> <ul> <li>delivery method? (/#/delivery/method) nope -></li> <li>billing method? (/#/billing/method) nope -></li> <li>delivery address? (/#/delivery/address) nope -></li> <li>billing address - (/#/billing/address) please start here.</li> </ul> <p>Looking forward to see some EmberJS folks to clear things up :)</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.
