Is there a method to get the latest topic of a subcategory that I receive in category.subcategories? I can use category.latestTopic to get the latest topic of the main category but I can’t use it for subcategories, any smart workaround for this? I would like to show the latest topic of a subcategory when i list the subcategories.

I’m not 100% sure of the context (can you post your code?) but I think you should be able to treat subcategories the same as parent categories.

So `category.latestTopic` would work the same for any category/subcategory. If you loop through each of the subcategories using `category.subcategories` you should be able to use `category.latestTopic` within that loop.

Hello, sadly it does not. behave the same way.  
Inside:

```javascript
<script type="text/x-handlebars" data-template-name="components/categories-only">
....
    {{#each categories as |c|}}
...

```

I can use `c.latestTopic`  
But inside after the above:

```javascript
...
  {{#each c.subcategories as |s|}}
...

```

I can’t use `s.latestTopic` It doesn’t return anything

Ohh I see now, thanks for the additional detail. It looks like we don’t include topics for subcategories on the category page at all, so using `latestTopic` definitely isn’t possible… I think the serializer would need to be modified in a plugin to accomplish this? (sorry, I’m not sure of the specifics for accomplishing that).

I don’t know, sadly I’m not that experienced with Discourse or Ruby or whatever part has to be modified.  
I hope someone can come up with a solution, I’ve been trying this for days and weeks by now.
