I'm getting this error when trying to update an 
event
with a new array of `places`: 
Reason: 'places' Expected 'PlaceUpdateManyInput', found not an object
Copy code
const UPDATE_EVENT_MUTATION = gql`
  mutation UpdateEventMutation($id: ID!, $title: String!, $slug: String!, $description: String, $dates: [String], $places: [PlaceInput]) {
    updateEvent(id: $id, title: $title, slug: $slug, description: $description, dates: $dates, places: $places) {
      id
      title
      description
      dates
      places {
        name
        url
      }
    }
  }
`;

// Resolver
updateEvent(parent, { id, title, slug, description, dates, places }, context) {
     return context.prisma.updateEvent({
       where: { id },
       data: { title, slug, description, dates: { set: dates }, places },
     });
   },

// graphql schema
type Mutation {
  updateEvent(id: ID!, title: String!, slug: String!, description: String, dates: [String], places: [PlaceInput]): Event
}

input PlaceInput {
  name: String!
  url: String
}

type Place {
  id: ID!
  name: String!
  url: String
}

type Event {
  id: ID!
  slug: String!
  title: String!
  description: String
  dates: [String]
  places: [Place]
  menus: [String]
}
@marcus @Harshit any idea of what could be wrong with my resolver?

Your call to Prisma does not use the nested mutation correctly. It is an just the array of places but it has to be an object that specifies the kind of nested mutation

thanks, is it the 
connect
or the 
create
that I have to use?
sorry for asking many questions. I'm still learning about prisma & graphql and this part of updating the nested objects is what I find most difficult to understand
with 
places: { create: places }
, I was able to save data, but it doesn't update it. It keeps increasing the records
with this:
Copy code
places: {
           update: {
             where: { id },
             data: { places }
           }
         }
I though it would update each place but it throws an error
I give up for now. Too much frustration and feeling sleepy. This is hard.
is this the correct way of doing it?
Copy code
places: {
           update: {
             where: { id: places.id },
             data: {
               name: places.name,
               url: places.url
             }
           }
         }

@joan: I don’t know. What do you want to exactly achieve? What should happen with the places?

Hi marcus. I managed to understand how it works and I fixed it by using 
connect
when adding places

What I want to do now is to add 
subscriptions
to update the UI whenever a new 
place
is added
