[v4] Want to add more data in the json response

[Neewd]

Hey,

I think the serializer would solve my problem but I found the documentation quite vague, so I'll explain what my need.

I have a manyThrough relation ship in a model, like: Picture taken in a ---> Location who belongs to a --> Country.
I can now have the number of pictures, but I would like to add this number when I retrieve all the Country like, Ok this country have 19 pictures taken through the locations.

How can I do this ?
Thanks :D

You can set up the manyThrough in reverse.

// Country.js

 pictures () {
    return this.manyThrough('App/Models/Picture', 'location')
  }

// Controller somewhere
 const pictures = await Country.query().with('pictures').fetch()
