AttributeError: type object 'User' has no attribute 'name'

Question

I’m new with 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 is giving me this error, because before using the django User class, I was using my own User definition and it worked. Why using the User class from the django authentication framework is giving 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 attribute ‘name’

Am I missing something?

Regards

PD: I’m using Django 2.0.4

I think you'd used user_obj.name in your code. Replace that with user_obj.username – Inclement

@JerinPeterGeorge no I'm not, the obj.name call i have in my project is country_gql = CountryType(id=country_db.id, code=country_db.code, name=country_db.name), where country_db is another model class. Thanks for you answer my friend. – Fretwell

The User model in django.contrib.auth.models has a name field. Try using first_name or last_name – Photocomposition

Answer 1

This is a cryptic error that happens when Django Model classes are accidentally used in code instead of graphene Type classes. For example, make sure that your query is something like

user = graphene.Field(UserType)

instead of

user = graphene.Field(User)

I made this same mistake a bunch of times -- maybe I'll make a pull request to make the error friendlier, e.g. "Object "User" is not a "DjangoObjectType" – Madrid

Thankyou, Problem solved, I am new to django, but have a php laravel background and i sometimes can not understand the errors that django throw at us. – Apiary

Well, it doesn't look like I'm ever going to get around to making that pull request. Be my guest, dear reader. – Madrid

Answer 2

As suggested by your error, Django's default User model does not have a field called name.

Instead, it has two similar fields, first_name, and last_name.

If you would like to use the combination of the two, use the get_full_name() method.

But my question is mor related to where the issue is? In my model or in my schema? because it doesn’t make any sense that User model doesn’t have any name attribute when en my entire project I’m not using obj.name because I don’t have it only for my country model which only has two field: name and code. :( – Fretwell
