groupby and multiple taxonomies?

[stephenmeehanuk]

Hi

Is it possible to use the new groupby operator to group entries by multiple categories? Or is there another way to do this?

I've got a divisions taxonomy, located at resources/views/divisions/show.antlers.html

I'm using this to output the entires from a products collection, when viewing a division term:

{{ title | wrap:h2.font-medium }}
{{ taxonomy from="divisions" collection="products" :slug:is="slug"}}
    <ul> 
        {{ entries }}
            <li><a href="{{ url }}">{{ title }}</a></li>
        {{ /entries }}
    </ul>
{{ /taxonomy }}

This is an example entry from the product collection:

---
id: 04757f84-712f-4c1a-93fa-e765b4241a65
blueprint: products
title: 'Automated Handling'
updated_by: a22581f2-580e-4041-81e2-e343df73d946
updated_at: 1653057700
p1:
  - automation-and-materials-handling
divisions: technologies-and-services
---

This entry has another taxonomy, called p1, other entries in this products collection have multiple taxonomies, p1, p2, p3 and p4.

I'm trying to list the entries based on the divisions taxonomy and then list/group the entries by p1, p2, p3 and p4 terms.

I can't wrap my head around the example in the docs, how it'd be applied to this.

Looking over the docs again, I was hoping this would work... but no joy?

{{ products = {collection:products} groupby (divisions, p1, p2, p3, p4) as 'entries' }}
  <h2>{{ title }}</h2>
  <ul>
    {{ entries }}
      <li><a href="{{ url }}">{{ title }}</a></li>
    {{ /entries }}
  </ul>
{{ /products }}

Any pointers would be appreciated.

Can p1, p2, p3, and p4 have multiple terms associated with the entry?

[stephenmeehanuk]

Thanks for the reply!

The taxonomies will be limited to max_items: 1, but an entry could have multiple taxonomies. E.g. divisions, p1 and p2. Another entry might only have divisions and p1

[JohnathonKoster]

Fantastic! And to make sure I got this right, if entries have divisions, p1 and p2 that is a separate group from entries having divisions and p1 ?

[stephenmeehanuk]

Yes, that's right.

Although thinking about it over the weekend, it needs to work slightly different from my original post.

Here's an example of an entry from collection:products. This entry has p1, p2, p3 and divisions taxonomy terms

---
id: 71f258bc-cc3f-45e2-83e5-e40fdcf55620
blueprint: products
title: Waterers
updated_by: a22581f2-580e-4041-81e2-e343df73d946
updated_at: 1649347749
p1:
    - precast-concrete
p2:
    - precast-products
p3:
    - agricultural-products
divisions: precast-concrete-products
---

This gets me part of the way, it simply filters collection:products by the division slug.

{{ taxonomy from="divisions" collection="products" :slug:is="slug"}}
    <ul> 
        {{ entries }}
            <li><a href="{{ url }}">{{ title }}</a></li>
        {{ /entries }}
    </ul>
{{ /taxonomy }}

But I'm looking for a way to group the entries by taxonomies and output the terms for each taxonomy.

Is this possible?
