Tridion Razor RenderComponentPresentation

Question

have you ran into the problem when defining a template in a component query?

When using DWT my call looked like this

<!-- TemplateBeginRepeat name="allItemsInFolder" -->
         @@RenderComponentPresentation()@@
    <!-- TemplateEndRepeat -->

This worked because I set the template in the component query. when I try to do it via razor, like this :

@foreach (var c in Package.allItemsInFolder){
        @c.RenderComponentPresentation()
}

It thinks that RenderComponentPresentation is a FieldName and wont render it correctly, there error I get is

DynamicItemFields: Key 'rendercomponentpresentation' Not Found In ItemFields

Any advice would be great!

Your solution seems fine, except for the hardcoding of the CT's TCM ID. So it sounds like you need a way to reference the component template without hardcoding the TCM ID. Have a look at the comments in the answer here: https://stackoverflow.com/a/10802912/1284894

The solutions discussed are to:

1. add a Parameter schema on the DWT TBB that specifies the template IDs, so that you can configure them across environments
2. the other option is to write a C# TBB that pushes all the CTs by name onto the package with the TCM ID as the value.

Here is a link to the post with a sample TBB that you can use for this: http://www.tridiondeveloper.com/the-solution-to-hardcoding-component-template-ids-in-nested-component-presentations

If this is Razor Mediator for Tridion (Alex Klock's extension), then you may want to use TridionObject:

@foreach (var c in Package.TridionObject.allItemsInFolder){
        @c.RenderComponentPresentation()
}

My current Solution is this, but I do not like it.

@foreach (var c in Package.allItemsInFolder){
    @RenderComponentPresentation(c.ID, "tcm:xx-xxxx-xxx")
}

Anything better out there?
