How to set cookies in Graphene Python mutation?

Wound up setting cookies via middleware.

class CookieMiddleware(object):

    def resolve(self, next, root, args, context, info):
        """
        Set cookies based on the name/type of the GraphQL operation
        """

        # set cookie here and pass to dispatch method later to set in response
        ...

In a custom graphql view, views.py, override the dispatch method to read the cookie and set it.

class MyCustomGraphQLView(GraphQLView):  

    def dispatch(self, request, *args, **kwargs):
        response = super(MyCustomGraphQLView, self).dispatch(request, *args, **kwargs)
        # Set response cookies defined in middleware
        if response.status_code == 200:
            try:
                response_cookies = getattr(request, CookieMiddleware.MIDDLEWARE_COOKIES)
            except:
                pass
            else:
                for cookie in response_cookies:
                    response.set_cookie(cookie.get('key'), cookie.get('value'), **cookie.get('kwargs'))
        return response
