Filtering entires by category

Hi there,

I am struggling to find a way to filter tags by category.

I have a category content model that consists of a slug and a title, both are short text fields. This content model is added to my blog posts as a reference object referencing many categories ( if that makes sense ).

On a single blog post page, I want to load more posts that have similar categories, but exclude the current post from the results.

The problem from what I read is, “Filtering by a linked collection entry is not supported right now”.

So I cannot create a graphQL query like this:

{
  articleCollection(
    where: {
      slug_not: "exclude-this-slug"
      categoriesCollection: {
        slug: "category"
      }
    }
  ) {
    items {
      title
    }
  }
}

I can get the articles doing a query like this:

{
  categoriesCollection (
    where: {
      slug: "category"
    }
  ) {
    items {
      linkedFrom {
        articleCollection {
          items {
            title
          }
        }
      }
    }
  }
}

But there seems to be no way to filter out the current post as the only filters I can add to the articleCollection within that query seems to be skip, limit, locale and preview.

Is there any way I can get related posts by using the category as a content model, as I am currently doing or is there perhaps a different solution to this?

Thanks in advance
