{
<p>@(Model.Value<string>("category"))</p>
}
Multiple items - without Models Builder
@if (Model.HasValue("categories"))
{
var categories = Model.Value<IEnumerable<string>>("categories");
<ul>
@foreach (var category in categories)
{
<li>@category</li>
}
</ul>
}
Single item - with Models Builder
@if (!Model.HasValue(Model.Category))
{
<p>@Model.Category</p>
}
Multiple items - with Models Builder
@if (Model.Categories.Any())
{
<ul>
@foreach (var category in Model.Categories)
{
<li>@category</li>
}
</ul>
}
Add values programmatically
See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the Content Service.
@using Umbraco.Cms.Core.Serialization
@using Umbraco.Cms.Core.Services
@inject IContentService ContentService
@inject IJsonSerializer Serializer
@{
// Create a variable for the GUID of the page you want to update
var guid = Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef");
// Get the page using the GUID you've defined
var content = ContentService.GetById(guid); // ID of your page
// Set the value of the property with alias 'categories'.
content.SetValue("categories", Serializer.Serialize(new[] { "News" }));
// Save the change
ContentService.Save(content);
}
Although the use of a GUID is preferable, you can also use the numeric ID to get the page:
@{
// Get the page using it's id
var content = ContentService.GetById(1234);
}
If Models Builder is enabled you can get the alias of the desired property without using a magic string:
@using Umbraco.Cms.Core.PublishedCache
@inject IPublishedContentTypeCache PublishedContentTypeCache
@{
// Set the value of the property with alias 'categories'
content.SetValue(Home.GetModelPropertyType(PublishedContentTypeCache, x => x.Categories).Alias, Serializer.Serialize(new[] { "News" }));
}
