Hi Lee,

Thanks for your (quick) response! And that's what I mean indeed. I need the Testimonial in my Razor View.

Each testimonial got a Full name (TextString) Quote (Richtext editor) and an Image (New Media Picker).

And if you state it like that it isn't very performant indeed. The initial thought was to create nodes and use a NoUrlComposer but if we've got a lot of testimonials the node count adds up on the Umbraco Cloud package (which is unnecessary if you can pick it as BlockList.

I'm not very familiar with the static dictionary/look/cache. Do you maybe have an example of this?

Thanks, Wesley

Hi Wesley,

Off the top of my head, it could be done as an extension method to UmbracoHelper, something like this (based on your code from above)...

using System;
using System.Collections.Generic;
using System.Linq;
using Umbraco.Core.Models.Blocks;
using Umbraco.Core.Models.PublishedContent;

namespace Umbraco.Web.Mvc
{
    public static class UmbracoHelperExtensions
    {
        private static readonly Dictionary<Guid, Testimonial> _lookup = new Dictionary<Guid, Testimonial>();

        public static Testimonial GetTestimonial(this UmbracoHelper helper, Guid key)
        {
            if (_lookup.Count == 0 &&
                helper.ContentAtRoot() is Home home &&
                home.Descendants<TestimonialOverview>().FirstOrDefault() is TestimonialOverview testimonialOverview &&
                testimonialOverview.Testimonials as IEnumerable<BlockListItem<Testimonial>> testimonials)
            {
                foreach (var testimonial in testimonials)
                {
                    if (_lookup.ContainsKey(testimonial.Content.Key) == false)
                    {
                        _lookup.Add(testimonial.Content.Key, testimonial);
                    }
                }
            }

            return _lookup.ContainsKey(key) == true
                ? _lookup[key]
                : null;
        }
    }
}

Note, I haven't tested this, excuse any typos or broken code, it's just something I quickly coded up. 😆

Then you would be able to call @Umbraco.GetTestimonial(item.Value) in your partial-views.

One pain point of this is that the static lookup would be caching the testimonial instances at the time of population. Meaning that if you updated a testimonial in the CMS, then the old version would still be cached. The cache would be invalidated on web-app restart, but if you need cache invalidation, then a better solution would probably need to be fleshed out.

Hope this helps get you in the right direction?

Cheers,

Thanks Lee!

I'll try that.

For now I've tested the (not very performant) loop version. It gets the content I want and is fast for now but if the number of testimonial grows the website gets slower...

@if (Model.Content.Testimonials is List<Guid> testimonialGuids && testimonialGuids.Any())
    {
        foreach (Guid testimonialGuid in testimonialGuids)
        {
            foreach (BlockListItem<Testimonial> testimonial in testimonialOverview.Testimonials.Where(t => t.Content.Key == testimonialGuid))
            {
                <h2>@testimonial.Content.Quote.ToString()</h2>
                <h2>@testimonial.Content.FullName</h2>
            }
        }
    }
