What's the Template file name when I tried to render ListPart content Items

[hylinux]

Hi, Everyone.

I got very confuse about this part:
I have create few Content Types: ArticlePage Content Type which have a ListPart. and the ListPart contain another ContentType: Article.

when I tried to render ArticlePage, I got Template: Content-AritclePage.cshtml. in this template, I will render ListPart by this code:

@await DisplayAsync(Model.Content.ListPart)

this code works well, it will render template file: ArticlePage-ListPart.cshtml.

when I tried to render detail list in ListPart, I wrote code in ArticlePage-ListPart.cshtml :

@foreach ( ContentItem contentItem in Model.ContentItems )
{
    @await Orchard.DisplayAsync(contentItem)
}

Per design, here's the contentItem should be Article Content Type. I created a copule themes files, include:
ArticlePage-ListPart-Aritcle.cshtml
Content-Article.cshtml
ListPart-Article.cshtml

but non of them was render.

would you share with me what's I did wrong? what's the correct theme file name?

thanks

@hylinux you are missing BuildDispay in your foreach

@foreach ( ContentItem contentItem in Model.ContentItems )
{
     @await Orchard.DisplayAsync(await DisplayManager.BuildDisplayAsync(contentItem , null, "Detail"))
}

This will render Content-Article.cshtml

Copy.

thanks for your sharing. I saw the document: https://docs.orchardcore.net/en/latest/docs/reference/core/Razor/, it saying:

DisplayAsync(ContentItem content, string displayType = "")

·Renders a content item with the corresponding display type.·

I suppose it just need a paramter named 'ContentItem'

which is mean I used the Razor Help function. not the OrchareCore function...

any idea what's the correct template file name for Razor Help fucntion `DisplayAsync'?

thanks agian.

also, look like this code it doesn't work too. :(\

@using OrchardCore.DisplayManagement;
@inject IDisplayManager<ContentItem> _displayManager

@foreach ( ContentItem contentItem in Model.ContentItems )
{
    @await DisplayAsync(await _displayManager.BuildDisplayAsync(contentItem, null))
    <b>Test1</b><br/>
}

and I checked the source code for Razor helper.

public static class OrchardRazorHelperExtensions
{
    public static async Task<IHtmlContent> DisplayAsync(this IOrchardDisplayHelper orchardDisplayHelper, ContentItem content, string displayType = "", string groupId = "", IUpdateModel updater = null)
    {
        var displayManager = orchardDisplayHelper.HttpContext.RequestServices.GetService<IContentItemDisplayManager>();
        var shape = await displayManager.BuildDisplayAsync(content, updater, displayType, groupId);

        return await orchardDisplayHelper.DisplayHelper.ShapeExecuteAsync(shape);
    }

it look like a correct syntax, but I don't know why it doesn't works.

ok, I got it.

I have to use detail DisplayType for it:

@foreach ( ContentItem contentItem in Model.ContentItems )
{
    @await Orchard.DisplayAsync(contentItem, "Detail")
  
}

it will take the template file "Content-Article.Detail.cshtml"

if I didn't put the DisplayMode, it will not point to "Content-Article.cshtml", which is werid. I guess it should be this code problem:

         var contentTypeDefinition = _contentDefinitionManager.GetTypeDefinition(contentItem.ContentType);

            if (contentTypeDefinition == null)
            {
                throw new NullReferenceException($"Content Type {contentItem.ContentType} does not exist.");
            }

            var actualDisplayType = String.IsNullOrEmpty(displayType) ? "Detail" : displayType;
            var hasStereotype = contentTypeDefinition.TryGetStereotype(out var stereotype);

            var actualShapeType = "Content";

            if (hasStereotype)
            {
                actualShapeType = contentTypeDefinition.GetStereotype();
            }

            // [DisplayType] is only added for the ones different than Detail
            if (actualDisplayType != "Detail")
            {
                actualShapeType = actualShapeType + "_" + actualDisplayType;
            }

in ContentItemDisplayManager.cs

if DisplayType is null or empty, it will always "Detail"
