得到“TypeError: __init__() 需要 1 个位置参数，但给出了 10 个”

Question

我正在尝试运行单元测试以查看我的数据库表是否正在按应有的方式保存信息。 但是，我不断收到此错误，

u1 = User("test", "user", "testuser123", "test@test.com", "password", None, "California", None, None)
TypeError: __init__()接受 1 个位置参数，但给出了 10 个”

我觉得这很奇怪，因为我提交了我的 model class 需要的所有数据。 这是我的代码：

模型.py 文件

class User (db.Model):
    """User in the system"""

    __tablename__ = "users" 

    id = db.Column( 
        db.Integer, 
        primary_key=True    
    )   
    firstname = db.Column(  
        db.Text,    
        nullable=False  
    )   
    lastname = db.Column(   
        db.Text,    
        nullable=False  
    )   
    username = db.Column(   
        db.Text,    
        nullable=False, 
        unique=True 
    )   
    email = db.Column(  
        db.Text,    
        nullable=False, 
        unique=True 
    )   
    password = db.Column(   
        db.Text,    
        nullable=False  
    )   
    image = db.Column(  
        db.Text 
    )   
    state = db.Column(  
        db.Text,    
        nullable=False  
    )   
    vax_date = db.Column(   
        db.Text,
        nullable=True  
    )   
    covid_status = db.Column(   
        db.Text,
        nullable=True
    )   

    review = db.relationship('Review', backref='users')

这是我的单元测试

class UserModelTestCase(TestCase):
    """Test case for User Model"""

    def setUp(self):
        """Create test client, add sample data."""

        db.drop_all()
        db.create_all()

        u1 = User("test", "user", "testuser123", "test@test.com", "password", None, "California", None, None)
        uid1 = 1111
        u1.id = uid1
        
        db.session.commit()

        u1 = User.query.get(uid1)

        self.u1 = u1
        self.uid1 = uid1

        self.client = app.test_client()

    def tearDown(self):
        res = super().tearDown()
        db.session.rollback()
        return res

    def test_user_model(self):
        """Does basic model work?"""

        u = User(
            firstname='test',
            lastname='case',
            username="testuser",
            email="test@testing.com",
            password="HASHED_PASSWORD",
            image=None,
            state="Arizona"
        )

        db.session.add(u)
        db.session.commit()

        # User should have no messages & no followers
        self.assertEqual(u.firstname, 'test')
