Nested Data Type

This package adds a Nested Datatype to Umbraco that can be used to create complex datatypes that are collections of one or more sets of existing data types.

Each instance can be configured with a list of child properties from those available in Umbraco. In addition the instance can be set to have a single child item, or an array of children items.

The data will be stored as a JSON array and get be easily retrieved with code like this.

@using Newtonsoft.Json.Linq;

var data = Model.Content.GetPropertyValue<JArray>("property");

foreach(var item in data.Children()) {

     var name = (string)item["subPropertyAlias"];

     @name

}

Or another example retrieving a single field directly.

@CurrentPage.productLinks[0].LinkDocument

Another option is to add a Strong Typed Model and a Property Value Converter for each data type created with this package like so.

Then you can simply do the following.

Model.Content.GetPropertyValue<School>(“property”).HasSchool(“Bob”)

Model.Content.GetPropertyValue<School>(“property”).Single(s => s.Name == “Bob”).Level

Or with the Umbraco Model Builders feature set up the following.

Model.Content.MyProperty.Sum(s => s.Level)

Note that the stored data is always an array even if the definition only allows one child.

Update 12/29/1016- Users no longer need settings or developer permissions to edit documents using this data type.
