Using a Generic Type in a Sitecore View with Glass Mapper

Customization

Models

POCOs, virtual

Glass Mapper required.

using System.Collections.Generic;
using Glass.Mapper.Sc.Configuration.Attributes;
using Glass.Mapper.Sc.Fields;

namespace Sample
{
    public class Parent<T>
    {
        [SitecoreId]
        public virtual Guid Id { get; set; }
        public virtual string Title { get; set; }
        public virtual IEnumerable<T> Children { get; set; }
    }

    public class Article
    {
        [SitecoreId]
        public virtual Guid Id { get; set; }
        public virtual string Title { get; set; }
        public virtual string Text { get; set; }
    }

    public class Teaser
    {
        [SitecoreId]
        public virtual Guid Id { get; set; }
        public virtual string Title { get; set; }
        public virtual Image Banner { get; set; }
    }
}

      

        
        
        
      

    

Views

Sitecore reference as a rendering of a view with a model pointing to Sample.Parent

(see below for Sitecore model definitions).

@inherits Glass.Mapper.Sc.Web.Mvc.GlassView<Sample.Parent<Sample.Article>>

<h1>@Editable(x => x.Title)</h1>
<div class="article-list">
    @foreach (var article in Model.Children)
    {
        <article class="article">
            <h2 class="article-title">@Editable(article, x => x.Title)</h2>
            <div class="article-content">@Editable(article, x => x.Text)</div>
        </article>
    }
</div>

      

        
        
        
      

    

@inherits Glass.Mapper.Sc.Web.Mvc.GlassView<Sample.Parent<Sample.Teaser>>

<h1>@Editable(x => x.Title)</h1>
<div class="teaser-list">
    @foreach (var teaser in Model.Children)
    {
        <article class="teaser">
            <h2 class="teaser-title">@Editable(teaser, x => x.Title)</h2>
            <div class="teaser-banner">@RenderImage(teaser, x => x.Banner)</div>
        </article>
    }
</div>

      

        
        
        
      

    

Sitecore Model Definition

Here's where I'm not sure if I did it right. These are the models that I have defined as Sitecore models (under /sitecore/layout/models

).

• Sample.Parent`1[T], Sample
  
  

  Also tried (no success):

  • Sample.Parent, Sample
    
    
  • Sample.Parent`1[Sample.Article, Sample], Sample
    
    
  • Sample.Parent<Sample.Article>, Sample
    
    )

• Sample.Article, Sample
  
  

• Sample.Teaser, Sample
  
  

Is it possible?

The sample code is simplified, but should capture what I am trying to do. Basically, I want to be able to use a generic type as a way to reuse more code. Due to external constraints, I cannot use anything other than Glass Mapper 3. The errors I see are either that Sitecore cannot find the type or "object reference not set" (it appears to be using Sitecore.Mvc.Presentation.RenderingModel, Sitecore.Mvc

as a model when it happens).

Or am I crazy? :) Is there a better way to do this?
