How to render sub block template from another block in Wagtail

Question

I am learning Wagtail and Django. And I got an issue with the following code.

Main goal is to have separate block templates for carousel items and carousel itself. When I start this code in Wagtail with added carousel items, I see that block template carousel_main.html was parsed by Wagtail but block template carousel_item.html was not. Most probably I am doing something wrong but I cannot seem to figure it out.

    class CarouselBlock(blocks.StructBlock):
        image = ImageChooserBlock()
        text = blocks.RichTextBlock(blank=True)

        class Meta:
            template = 'carousel_item.html'

    class Carousel(blocks.StructBlock):
        carousel = blocks.ListBlock(CarouselBlock(),blank = True)

        class Meta:
            template = 'carousel_main.html'

    class HomePage(Page):
        carousel_field = StreamField(
            [
                ('carousel',Carousel()),

            ],blank = True
        )

        content_panels = Page.content_panels + [
            StreamFieldPanel('carousel_field')
        ]

First, have you already created carousel_main.html and carousel_item.html at the top of your templates directory? (You can place it under the top of your home/templates if you'd like.)

If you're still seeing the welcome page when you use manage.py runserver, you have to change the contents of your home_page.html template as described in the Wagtail tutorial.

Second, have you already used the include_block template tag in home_page.html and carousel_main.html? There are step-by-step instructions on how to use it in the Wagtail docs.

Other than that, you're off to a great start.
