Encounter an error when trying the example

[MingzXIE]

Hi there,

I was trying the example code in the Readme file. However, I met this error:

  File "C:\Users\ming\.pyenv\pyenv-win\versions\3.9.5\lib\runpy.py", line 197, in _run_module_as_main

This is my schema file which is the same as the example:

import graphene
from sql.models.credential import CredentialModel
from graphene_sqlalchemy import SQLAlchemyObjectType

class User(SQLAlchemyObjectType):
    class Meta:
        model = CredentialModel

class Query(graphene.ObjectType):
    users = graphene.List(User)

    def resolve_users(self, info):
        query = User.get_query(info)
        return query.all()

schema = graphene.Schema(query=Query)

And my model file:

from sql.models import Base
from sqlalchemy import Column, String, BigInteger

class CredentialModel(Base):
    __tablename__ = 'Credential'
    id = Column(BigInteger, primary_key=True)
    username = Column(String(50))
    password = Column(String(30))

Did I miss something? Many thanks!

By the way the version I am using is:

graphene-sqlalchemy==2.3.0

[chrisberks]

It looks like you're using Graphene v3. Version 3 is still in beta and is not compatible with the latest stable release of Graphene-SQLAlchemy.

Thanks @chrisberks

Sine we are using FastAPI, so we need starlette-graphene3 which requires Graphene V3

Just close this issue since it looks like a package version issue
