flask中models定义表名时最好用小写字母

class Employee(db.Model, BaseDbModel):
    id = db.Column(db.Integer, autoincrement=True, primary_key=True)
    name = db.Column(db.String(30), nullable=False)
    address = db.Column(db.String(100), nullable=True)
    phone = db.Column(db.String(300), nullable=True)
    post =db.Column(db.String(50), nullable=True)
    note = db.Column(db.String(200), nullable=True)
    company_id = db.Column(db.Integer, db.ForeignKey('company.id'), nullable=False)

    __tablename__ = 'employee'    # 如果大写，通过flask-migrate迁移进mysql还是小写的表名，如果再次迁移，会因表名不同，而重复操作报错。

    def __init__(self, name):
        self.name = name




常用操作命令：

python manage.py db migrate
python manage.py db upgrade
python manage.py runserver 或 python manage.py runsrever -h 192.168.2.13 -p 8080
