Order by totalCount with per-query custom filtering applied

[jiqiang90]

Summary

Allow order by with totalCount

Additional context

I think this will expand on this issue #25

Currently we can filter with aggregate result, but not allow output to order by it.

For example, we have schema as follow:

type Author @entity{
  id:ID!
}

type Book @entity{
  id:ID!
  author: Author! //Fk author_id
  year: Int!
}

And we want to sort authors by the amount of books written after a certain year.

With pg-aggregates and connection-filter I could query list of authors and books written after year 1995,

However, the BOOKS_COUNT_DESC does not order by filtered result, it counts all books belong to author and order desc.

query {
  authors(
    orderBy: BOOKS_COUNT_DESC
    filter: {
      books: { 
        aggregates: { 
          distinctCount: { id: { greaterThan:"0" } } } 
      }
    }
  ) {
    nodes {
      id
      books(filter:{year:{greaterThanOrEqualTo:1995}}){
        totalCount
        nodes{
          id,
          year
        }
      }
    }
  }
}

Is there a generic solution for this? Rather than something like create additional plugin and make sortable on compute column. Thank you !

I don't think so.
