    <p>Is there a way to map a JSON data object to an observable array and then in turn have each item of the observable array be initialized into a specific type of view model?</p> <p>I've looked at all of knockout's documentation along with the knockout and mapping examples here and I can't find any answer that works for what I'm after.</p> <p>So, I have the following JSON data:</p> <pre><code> var data = { state : { name : 'SD', cities : [{ name : 'Sioux Falls', streets : [{ number : 1 }, { number : 3 }] }, { name : 'Rapid City', streets : [{ number : 2 }, { number : 4 }] }] } }; </code></pre> <p>And I have the following view models:</p> <pre><code>var StateViewModel = function(){ this.name = ko.observable(); this.cities = ko.observableArray([new CityViewModel()]); } var CityViewModel = function(){ this.name = ko.observable(); this.streets = ko.observableArray([new StreetViewModel()]); } var StreetViewModel = function(){ this.number = ko.observable(); } </code></pre> <p>Is it possible, with the given data structure and using knockout's mapping plugin, to have the resulting StateViewModel contain an observableArray populated with 2 CityViewModels, and each CityViewModel containing an observableArray populated with 2 StreetViewModels?</p> <p>Currently using the mapping plugin I'm able to get it to map to a StateViewModel, but the 'cities' and 'streets' collections are populated with generic objects instead of instances of my City and Street view models.</p> <p>They end up with the correct observable properties and values on them, they're just not instances of my view models, which is what I'm after.</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.
