How to access parent field parameters within child resolver

I’m trying to build a schema using Graphene that will support the following example query:

{
  form(id:1) {
    visits(start:1498863600, end: 1498950000) {
      total
    }
  }
}

The expected result from this would be something like this:

{
  "data": {
    "form": {
      "visits": {
        "total": 1123
      }
    }
  }
}

So far, I’ve come up with a schema that’s similar to the following. However I’m not sure how to access the id parameter on the form field from within the visits resolver. I need this id parameter in the visits resolver as I need to retrieve sessions from the DB for a specific form and between a time range (start and end).

import graphene
from lib import DBI


class ResultSetType(graphene.ObjectType):
    total = graphene.Int()

    def resolve_total(self, args, context, info):
        return 1000  # Hardcoded example


class FormType(graphene.ObjectType):
    id = graphene.ID()
    visits = graphene.Field(ResultSetType)

    def resolve_visits(self, args, context, info):
        """
        I understand that here I can access the 'start' and 'end'
        parameters for this field using args.get('start'), but how
        do I access the 'id' parameter from the parent 'form' field?
        
        My naive attempt of using`args.get('id')` returns `None`
        """
        return DBI.get_form_sessions(form_id=args.get('id'), start_ts=args.get('start'), end_ts=args.get('end'))


class RootType(graphene.ObjectType):
    form = graphene.Field(FormType, id=graphene.ID())

    def resolve_form(self, args, context, info):
        return FormType(id=args.get('id'))

How do I access parent field parameters from within a child field resolver?

For anyone facing a similar issue, I worked out how to do this. self.id holds the ID of the FormType object.

For example, the following would be a replacement for the resolve_visits method above:

    def resolve_visits(self, args, context, info):
        return DBI.get_form_sessions(form_id=self.id, start_ts=args.get('start'), end_ts=args.get('end'))
