    In need of Razor syntactic sugar to help with 'is published' checking.

    Hi all

    Here's a pretty common scenario we face, and I'm wanting a way to make this DRYer. 

    How can I separate out all the logic above the 'HTML HERE' line into something re-usable?

    @inherits umbraco.MacroEngines.DynamicNodeContext

@{
    if (Model.HasProperty("relatedPages") && Model.HasValue("relatedPages")) 
    {
        List publishedRelatedPages = new List();
        foreach (var nodeId in @Model.RelatedPages)
        {
            var page = Model.NodeById(nodeId.InnerText);
            if (page.Id != 0)
            {
                publishedRelatedPages.Add(page);
            }
        }
        if(publishedRelatedPages.Count > 0)
        {
            @* ---------- HTML HERE ---------- *@
            <h2>Related Pages</h2>
            <ul>
                @foreach (var page in publishedRelatedPages)
                {
                    <li>
                        <a href="http://mce_host/forum/developers/razor/@page.NiceUrl">@page.Position(). @page.Name</a>
                    </li>
                }
            </ul>
        }
    }
}

    Hi Murray,

    How about creating a @helper method, which can be put in App_code folder and be used on any of your Razor files? Or an extension method on the Model that returns a DynamicNodeList, probably taking your propery alias as additional parameter?

     

    Hope this helps.

    Regards,

    /Dirk

    BTW: related pages is uComponents MNTP saving in XML format.

    @Dirk unfortunately you can't have extension methods on dynamic objects, I tried that.

    However I just tried the obvious solution again and this time it works, I don't know If I failed last time or because we updated to latest macroEngine, but here it is, moving it into a static helper class:

    using System.Collections.Generic;
using System.Web;
using umbraco.MacroEngines.Library;

namespace Terabyte.Umbraco.Extensions
{
    public static class DynamicNodeExtensions
    {
        public static IEnumerable<dynamic> GetPublishedNodes(dynamic property)
        {
            foreach (var nodeId in property)
            {
                var page = (new RazorLibraryCore(null)).NodeById(nodeId.InnerText);
                if (page.Id != 0)
                {
                    yield return page;
                }
            }
        }
    }
}

    and the razor:

    @inherits umbraco.MacroEngines.DynamicNodeContext
@using Terabyte.Umbraco.Extensions;
@{
    IEnumerable<dynamic> pages = DynamicNodeExtensions.GetPublishedNodes(@Model.RelatedPages);
    if (pages.Any())
    {
        <h2>Related Pages</h2>
        <ul>
            @foreach (var page in pages)
            {
                <li>
                    <a href="@page.NiceUrl">@page.Name
                </li>
            }
        </ul>
    }
}

    Improvements welcome
