Multiple Mutaion classes in schema

[mzohaibqc]

I have multilpe services and each have lot of mutations like

class SnMutations(graphene.ObjectType):
    # Event mutations
    create_event = CreateEvent.Field()
    update_event = UpdateEvent.Field()
    delete_event = DeleteEvent.Field()

    # Venue mutations, Meetup does not allow to update a venue. Also it does not make sense.
    create_venue = CreateVenue.Field()

    # EventOrganizer mutations
    create_event_organizer = CreateEventOrganizer.Field()
    update_event_organizer = UpdateEventOrganizer.Field()
    delete_event_organizer = DeleteEventOrganizer.Field()

    # Authorization mutations
    refresh_token = RefreshToken.Field()
    add_social_network_credentials = AddSocialNetworkCredentials.Field()

and

class CandidateMutation(graphene.ObjectType):
    create_candidate = CreateCandidate.Field()
    update_candidate = UpdateCandidate.Field()

and more

Now I want to create schema with all these mutations but I want to send query for each mutation under a specific key like sn_mutations and candidate_mutations for candidate service.

mutation {
    sn_mutations {
         create_event (some values) {

        }
    }
}

But I can only pass a single class in schema.

schema = Schema(query=Query, mutation=SnMutation, auto_camelcase=False)

I tries graphene.AbstractType and Inherited main Mutation class from all other Mutation class but in this way I can not divide mutation for every service in query under a specific key like sn_mutations and candidate_mutations.
Any help is most appreciated.

Hey @mzohaibqc
Just note that while using hierarchies in mutations is valid under the GraphQL spec, it will not work if you use Relay on your client to call it.
Relay enforces all mutations to be top-level: facebook/relay#551

Its very annoying, but thats the way it is :(

Anyway, if you still want to do it all you need to do is define a root:

class MutationRoot(graphene.ObjectType):
   sn_mutations = graphene.Field(SnMutations)

   def resolve_sn_mutations(self, *_):
       return SnMutations()

As Eran pointed, all mutations are enforced to be top level.

Related spec improvement in the GraphQL spec: graphql/graphql-spec#252

Hi @mzohaibqc . We're currently going through old issues that appear to have gone stale (ie. not updated in about the last 6 months) to try and clean up the issue tracker. If this is still important to you please comment and we'll re-open this.

Thanks!
