How to get user context inside afterFetch callback or filter GraphQL output?

[n8tb1t]

Hi I need to filter graphQL results on server side and replace some object values with default parameters based on current user and some DB settings.

The problem is that is that if I try to filter the result array in a controller, the relational fields queried by GRAPHQL using some inner queries.

I can do what I need in afterFetch callback, but I NEED an access to user context, is there a way to get it?

{
  "data": {
    "users": [
      {
        "email": "user1@localhost.localhost",
        "turtle_wallets": [
          {
            "owner": {
              "email": "user1@localhost.localhost"
            },
            "ins": [],
            "id": "5dc96922a9370b24cc914618",
            "address": "turtle_walllet_one"
          }
        ],
        "articles": [
          {
            "author": {
              "email": "user1@localhost.localhost"
            }
          }
        ]
      },
      {
        "email": "user2@localhost.localhost",
        "turtle_wallets": [
          {
            "owner": {
              "email": "user2@localhost.localhost"
            },
            "ins": [
              {
                "from": {
                  "owner": {
                    "email": "user1@localhost.localhost"
                  }
                }
              },
              {
                "from": {
                  "owner": {
                    "email": "user1@localhost.localhost"
                  }
                }
              }
            ],
            "id": "5dc96938a9370b24cc914619",
            "address": "turtle_wallet_two"
          }
        ],
        "articles": [
          {
            "author": {
              "email": "user2@localhost.localhost"
            }
          }
        ]
      }
    ]
  }
}

my object look like this, I can sanitize it and replace the email with custom value in User.js controller, but graphQL will resolve all the relational objects data by some inner method and display the initial values.

Hello! For this kind of need, I suggest you use a custom Query that manages your data as you want.
Here is the documentation for that https://strapi.io/documentation/3.0.0-beta.x/plugins/graphql.html#customise-the-graphql-schema
