Add property to all IContent?
In case anyone ever stumbles across this:
- I wish you the best of luck.
- The solution was to use an IContentApiModelFilter instead and append the property just before the content is being sent to the client.
The solution looks like this:
[ServiceConfiguration(typeof(IContentApiModelFilter), Lifecycle = ServiceInstanceScope.Singleton)]
public class CustomContentApiModelFilter : ContentApiModelFilter<ContentApiModel>
{
private readonly IContentLoader contentLoader;
private readonly IContentTypeRepository contentTypeRepository;
private const string CONTENT_TYPE_GUID = "ContentTypeGuid";
public CustomContentApiModelFilter(IContentLoader contentLoader, IContentTypeRepository contentTypeRepository)
{
this.contentLoader = contentLoader;
this.contentTypeRepository = contentTypeRepository;
}
public override void Filter(ContentApiModel contentApiModel, ConverterContext converterContext)
{
// apply any filtering as needed... etc
contentApiModel.Properties[CONTENT_TYPE_GUID] = Guid.Empty.ToString("N");
if (contentApiModel.ContentLink.Id != null && contentApiModel.ContentLink.Id.HasValue)
{
var content = contentLoader.Get<IContent>(new ContentReference(contentApiModel.ContentLink.Id.Value));
var contentType = content.ContentTypeID;
var type = contentTypeRepository.Load(contentType);
if (type != null && type.GUID != Guid.Empty)
{
contentApiModel.Properties[CONTENT_TYPE_GUID] = type.GUID.ToString("N");
}
}
}
}

I am trying to add a property to all IContent objects coming out of the Content Delivery API (v3).
I'm trying with a ContentFilter like so:
[ServiceConfiguration(typeof(IContentFilter), Lifecycle = ServiceInstanceScope.Singleton)] public class CustomContentFilter : ContentFilter<IContent> { public override void Filter(IContent content, ConverterContext converterContext) { content.Property.Add("TESTNAME", new PropertyString("TESTVALUE")); } }However, this doesn't seem to change the results coming out of the content delivery API.
What would be the recommended approach to inject a new property to all instances of IContent?
PS- the property I am trying to inject is actually the Content Type identifier, as I feel that this will be much more reliable for the consuming application. The content types array that exposes the C# model type feels really fragile to me, as a refactor of code could break that.
