Question

class Contacts(db.Model):
    """
    sno, name, email, phone_num, msg, date
    """
    sno = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    email = db.Column(db.String(20), nullable=False)
    phone_num = db.Column(db.String(12), nullable=False)
    msg = db.Column(db.String(120), nullable=False)
    date = db.Column(db.String(12), nullable=True)

Traceback (most recent call last): File "C:/Users/rithi/Flask_Blog/main.py", line 11, in class Contacts(db.Model): File "C:/Users/rithi/Flask_Blog/main.py", line 15, in Contacts sno = db.Column(db.Integer, primary_key=True) TypeError: Column() got an unexpected keyword argument 'primary_key'

Answer 1

我收到此错误: 类型错误:column() 获得意外的关键字参数“nullable”

原因是我写的是column()而不是Column()。仔细看看你的代码，这只是拼写错误..
