Description

We use sqlmodel and SQLAlchemy to define and save data models. When SQLAlchemy try to create an instance based on the query result, it calls new of ModelMetaclass. However, the new does not create pydantic_private when there is no private_attributes. It errors out when we try to compare objects by calling eq due to self.pydantic_private == other.pydantic_private . We get AttributeError object has no attribute 'pydantic_private'

It seems like some part of is missing in SQLModelMetaclass.__new__
For example, in pydantic BaseModel.model_construct, there is a code block as following but it is missing from SQLModelMetaclass.__new__

        if cls.__pydantic_post_init__:
            m.model_post_init(None)
            # update private attributes with values set
            if hasattr(m, '__pydantic_private__') and m.__pydantic_private__ is not None:
                for k, v in values.items():
                    if k in m.__private_attributes__:
                        m.__pydantic_private__[k] = v

        elif not cls.__pydantic_root_model__:
            # Note: if there are any private attributes, cls.__pydantic_post_init__ would exist
            # Since it doesn't, that means that `__pydantic_private__` should be set to None
            _object_setattr(m, '__pydantic_private__', None)

This is also an issue with __pydantic_extra__.

@gp1105739 Have you found a work around for this?

[Zdong104]

do:
pip install --upgrade llama_index qdrant_client pydantic
helped me to solve the problem, if you are also dealing with llamaindex

Hi @Zdong104, I'm facing the same even after updating packages. Can you take a look and suggest anything?
