AttributeError: object of type 'user' has no attribute 'name'

Freddie Martinez Garcia

I am new to graphene and I have this:

from django.contrib.auth.models import User

class UserType(DjangoObjectType):
    class Meta:
        model = User

Basically, using Django's User class gives me this error because before using the django User class I used my own User definition and it worked. Why does using the User class from the django authentication framework give me the error mentioned in the title:

File "/usr/local/lib/python3.6/site-packages/graphql/type/typemap.py" line 60 in reducer if type.name in map: AttributeError: type object 'User' has no property 'name''

Am I missing something?

greeting

PD: I'm using Django 2.0.4

This error occurs when Django model classes are accidentally used in code instead of graphene type classes. For example, make sure your query is something like

user = graphene.Field(UserType)

replace

user = graphene.Field(User)
