from sqlalchemy import Column, Integer, String, create_engine, Table, MetaData
from fastapi import FastAPI
from sqladmin import Admin, ModelView

engine = create_engine(
    "sqlite:///example.db",
    connect_args={"check_same_thread": False},
)

metadata = MetaData()

User = Table(
    "users",
    metadata,
    Column("id", Integer, primary_key=True),
    Column("name", String),
)
metadata.create_all(engine)

class UserAdmin(ModelView, model=User):
    column_list = [User.columns.id, User.columns.name]

app = FastAPI()
admin = Admin(app, engine)

admin.add_view(UserAdmin)

  File "/Users/sheldy/projects/test-sqladmin/test.py", line 20, in <module>
    class UserAdmin(ModelView, model=User):
  File "/Users/sheldy/projects/test-sqladmin/venv/lib/python3.11/site-packages/sqladmin/models.py", line 83, in __new__
    if not model:
  File "/Users/sheldy/projects/test-sqladmin/venv/lib/python3.11/site-packages/sqlalchemy/sql/elements.py", line 748, in __bool__
    raise TypeError("Boolean value of this clause is not defined")
TypeError: Boolean value of this clause is not defined

I read sqladmin sources and realized that your code is addicted to orm

If I change if not model condition to if model is None I will receive the following error

  File "/Users/sheldy/projects/test-sqladmin/test.py", line 20, in <module>
    class UserAdmin(ModelView, model=User):

    cls.pk_columns = get_primary_keys(model)
