Show rank on discussion page

w-4

Hello,
I modified the tags extension and added a column rank to the table discussion_tag. (This is to show a rank on the discussion page - f.e. #1 trending in Test-Tag. )

How would I get that column inside the API tags relationships object?

    "tags": {
        "data": [
          {
            "type": "tags",
            "id": "1"
          },
          {
            "type": "tags",
            "id": "2"
          }
        ]
      }

Many thanks to those that can answer.

Alternatively, how would I serialize the rank into the API attributes..
like this:

 "rank":  [
          {
            "tagId": "1", 
            "rank": "10"
          },
          {
            "tagId": "2",
            "rank": "5"
          }
        ]

the JSON:API spec doesn't have a way to include pivot attributes as far as I know. So the only solutions are to either add the pivot data into the relationship resource, or to make the pivot data into its own intermediate resource.

That first solution is how Flarum dealt with the discussion_user state. You can see the code here https://github.com/flarum/core/blob/master/src/Api/Serializer/DiscussionSerializer.php#L38

The second solution can be found in https://github.com/clarkwinkelmann/flarum-ext-who-read/blob/master/src/Extenders/DiscussionAttributes.php#L46 where I wanted to get the list of every user who read a discussion and their read time. I added a new serializer in between, transforming it from a single many-to-many relationship into two separate one-to-many and one-to-one relationships.
