Adding DjangoModelFormMutation to schema raises import error

Hi there!

I try to use the awesome DjangoModelFormMutation but when I add the mutation to the schema I always get this error:

Could not import 'project.config.schema.schema' for Graphene setting 'SCHEMA'. AttributeError: 'NoneType' object has no attribute '_meta'.

Here’s my setup:

class Pet(models.Model):
    name = models.CharField()

class PetForm(forms.ModelForm):
    class Meta:
        model = Pet
        fields = ('name',)

class PetMutation(DjangoModelFormMutation):
    class Meta:
        form_class = PetForm

class PetMutations(graphene.ObjectType):
    pet = PetMutation.Field(description="Pets!")


class Mutation(PetMutations,
               graphene.ObjectType):
    pass

schema = graphene.Schema(query=Query, mutation=Mutation)

Any ideas what I might be doing wrong?

Thanks! Ron

Aaaaaaaaaaaaaaaaad I found the solution:

class PetCrudMutation(DjangoModelFormMutation):
    pet= graphene.Field(PetType)
    class Meta:
        form_class = PetForm

I’m going to add this to the documentation 😃

django-graphene is trying to import your schema file and is encountering another error along the way. I would recommend doing a manage.py shell and attempt manually importing the schema. This way you can see the import error without other code eating the message.
