Render Multiple Content Types in One Loop with Hugo

Hugo has a way of creating views for content types that can be rendered anywhere on the site. Today I learned that if a template cannot be found, then no error occurs. Frustrating to debug but a useful feature once figured out. Using this knowledge, I have created a way to show only certain types of content in my homepage feed without complicated logic.

Current solutions

I currently have three content types: blogs, projects, and quotes. On my feed, I only want to highlight the blog posts and quotes. Suggestions online required additional logic that I think would get complicated over time.

One of the solutions is to only render if a certain type is found:

{{ range .Site.Pages.ByPublishDate }}
    {{ if or (eq .Type "blog") (eq .Type "quote")}}
   <li>{{ .Title }}</li>
{{ end }}

As I start adding more post types then I think I will struggle to maintain this list of types.

My solution

Using the 'no error' feature to .Render a specific content view means that I can create a folder structure that determines rendering. We'll call the view we want to render summary. We can then update the layouts folder for each content type to have a summary.html template.

├── _default
│   ├── single.html
├── blog
│   ├── single.html
│   └── summary.html
├── projects
│   ├── single.html
├── quote
    ├── single.html
    └── summary.html

Now that the blog and quote types have a summary template, we can update the logic from the Current Solution example.

{{ range .Site.Pages.ByPublishDate }}
    {{ .Render "summary" }}
{{ end }}

What happens when this runs? All of the content pages are loaded into the range but only the blog and quote types are actually rendered.
