I get the message
Variable '$aufmassVom' got invalid value ''; Date cannot represent value: ''
when I send this graphql mutation with an empty value for "aufmassVom":
mutation {
createParzelle(standort: "test", aufmassVom: "", besonderheiten: "test"){
id
standort
aufmassVom
besonderheiten
}
}
My schema.py looks like that:
import graphene
from graphene_django import DjangoObjectType
from parzelle.models import Parzelle
from graphql import GraphQLError
from graphql.validation import ValidationRule
class ParzelleType(DjangoObjectType):
class Meta:
model = Parzelle
class CreateParzelle(graphene.Mutation):
id = graphene.Int()
standort = graphene.String()
aufmassVom = graphene.Date(required=False)
besonderheiten = graphene.String()
class Arguments:
standort = graphene.String()
aufmassVom = graphene.Date(required=False)
besonderheiten = graphene.String()
def mutate(self, info, standort, aufmassVom, besonderheiten):
if not aufmassVom:
return GraphQLError('Required field date is missing')
parzelle = Parzelle(standort=standort, aufmassVom=aufmassVom, besonderheiten=besonderheiten)
parzelle.save()
return CreateParzelle(
id=parzelle.id,
standort=parzelle.standort,
aufmassVom=parzelle.aufmassVom,
besonderheiten=parzelle.besonderheiten
)
I would expect that I get the message "Required field date is missing" as defined in my schema.py if the value for "aufmassVom" is null (empty) and not the message "Variable '$aufmassVom' got invalid value ''; Date cannot represent value: ''".
If I change the type of "aufmassVom" from date to string everything works as expected.
What I'm doing wrong?
