Hi! I'm running into an issue with setting up a subscription that checks for changes to a field that references another type. For example, this subscription works fine (data is received if the "username" field is ever updated for the current user):

subscription userPosts {
  User(
    filter: {
      updatedFields_contains: "username"
    }
  ) {
    mutation
    node {
    	posts {
        createdBy {
          name
        }
        description
        status
    	}
    }
    updatedFields
  }
}

But when I switch

updatedFields_contains

to a field that references another type (i.e. "posts" field in User type references many Posts), any updates to my Post data will not be intercepted by the subscription:

subscription userPosts {
  User(
    filter: {
      updatedFields_contains: "posts" <----- nothing happens when Post data is updated
    }
  ) {
    mutation
    node {
    	posts {
        createdBy {
          name
        }
        description
        status
    	}
    }
    updatedFields
  }
}

Here is my User schema:

type User implements Node {
  auth0UserId: String @isUnique
  comments: [Comment!]! @relation(name: "CommentsByUser")
  createdAt: DateTime!
  id: ID! @isUnique
  name: String!
  posts: [Post!]! @relation(name: "PostsByUser")
  updatedAt: DateTime!
  username: String
}

Is there another way to use

updatedFields_contains

with a field that references another type? Thanks!

@bobbyt You can't use a second subscription on Posts?

Hi @agartha yes, sorry I meant any changes to a user's posts (adding/updating/deleting) should cause the subscription to return data

Then you need a seperate subscription on Posts

Understood. I tried doing a subscription on Post, but it only returns the created/updated Post, when what I really want is something similar to allPosts:

subscription allUserPosts {
	Post (
  	filter: {
      mutation_in: [CREATED, UPDATED, DELETED]
    }
  ) {
  	mutation
  	node {
    	description
  	}
  }
}

Then you need to combine your subscription with a refetch strategy

I'm using this in a React Native app (with Apollo) where the data returned will update a UI list component

The data returned should be merged into your local data store

ok, great thanks! i will look at the example and the Apollo docs

ha, nice 😆
