Rendering a ContentField with the default renderer

Topics: Customizing Orchard
Mar 26, 2013 at 3:50 AM
I'm trying to customise the rendering for a content type I've created called "Banner Image". This is my View file at the bottom of this post (Content-BannerImage.Summary.cshtml).

I've used the 'Markdown' field for my title field. However... I can't figure out how to access the Markdown rendering from here. I've tried just getting the ContentField object and calling @Display() but it doesn't work, it just puts out "Orchard.Core.Common.Fields.TextField". Could someone please tell me how I can render this field using the Markdown module's renderer?
    var imageUrl = ((ContentItem)Model.ContentItem).Parts.SelectMany(p => p.Fields).Where(f => f.Name == "Image").First().Storage.Get<string>(null);

    var titleField = ((ContentItem)Model.ContentItem).Parts.SelectMany(p => p.Fields).Where(f => f.Name == "Title").First();

@if (HasText(imageUrl))
    <div class="banner-image">
        <img src="@Href(imageUrl)" width="698" />
        <div class="overlay">

There is no markdown field that I know of. There is a text field that you can configure for Markdown. You can access its value through the Value property.

Yes, sorry it's a text field configured as Markdown. However if I try to access the value through the Value property:
var titleValue = ((ContentItem)Model.ContentItem).Parts.SelectMany(p => p.Fields).Where(f => f.Name == "Title").First().Value;
This doesn't compile/crashes.

I can access it like follows:
string titleValue = ((ContentItem)Model.ContentItem).Parts.SelectMany(p => p.Fields).Where(f => f.Name == "Title").First().Storage.Get<string>(null);
However then I am just left with a string and no way to render as HTML. I don't want to have to bring Markdown libs into the Theme just to render it... I just want to go hey field, render yourself.

Another option is I find the shape in the model and then call @Display() on the shape... but then I get all the extra stuff rendered with it like the fieldname that I don't want. Then I would have to create another view template to override the rendering of that, and well... things are just getting a little out of hand for doing a simple rotating banner!

The Value property of the shape should already be translated into HTML, so Model.Value from a text field template override should do the trick.

Thanks Bertrand. Here's my solution (based on this tutorial):

I modified the function from the tutorial so that it looks in alternates instead of just the type, this way I can specify exactly the field I'm looking for. I must say... this feels loose and hacky, but I don't know a better way.
public static dynamic Find(IShape model, string name)
    var zones = new Dictionary<string, object>();
        .GetMembers(_nullFunc, model, zones);
    foreach (var key in zones.Keys
        .Where(key => !key.StartsWith("_")))

        var zone = zones[key] as IShape;
        if (zone == null ||
            zone.Metadata.Type != "ContentZone") continue;
        foreach (IShape shape in ((dynamic)zone).Items)
            if (shape.Metadata.Alternates.Any(a => Regex.IsMatch(a, "^" + name, RegexOptions.IgnoreCase))) {
                return shape;    
    return null;
Then in my View:
dynamic foundShape = ShapeHelper.Find((Shape)Model, "Fields_Common_Text__Title");
var titleField = foundShape.Value;

You don't need to resort to finding shapes like that if you simply render a local zone, e.g. @Display(Model.TitleZone), and use to place the text field into that TitleZone (assuming that you are customizing a content item template, which you seem to be doing).

Thanks skywalker, I didn't know about local zones. I guess one annoyance with doing it that way is I have to override the text field template (because I don't want to display the field name and surrounding div). So if I have several fields on a content item then I will potentially need to customise the text field template for each one..

Perhaps, but only if you intend to do customizations for each field. If the only thing to be changed for a text field is to remove the display name and surrounding div, you only have to do that once in your template override.

Alternatively, you could file a bug requesting that we add a lazy field property to the TextField and BodyPart that returns the transformed value. Personally I think it makes sense, and actually needed this today (but solved it differently by adding such property to my custom part). It might be something worth considering.
