我目前正在尝试使用 bcrypt 从我的种子中加密/散列我的密码并将它们存储在 MYSQL 中，但它一直给我相同的密码。我正在使用python。任何帮助，将不胜感激！

User.py

from app.db import Base
from sqlalchemy.orm import validates
from sqlalchemy import Column, Integer, String
salt = bcrypt.gensalt()


class User(Base):
  __tablename__ = 'users'
  id = Column(Integer, primary_key=True)
  username = Column(String(50), nullable=False)
  email = Column(String(50), nullable=False, unique=True)
  password = Column(String(200), nullable=False)

  @validates('email')
  def validate_email(self, key, email):
    # make sure email address contains @ character
    assert '@' in email

    return email


@validates('password')
def validate_password(self, key, password):
  assert len(password) > 4

  # encrypt password
  return bcrypt.hashpw(password.encode('utf-8'), salt)

seeds.py

from app.models import User
from app.db import Session, Base, engine

# drop and rebuild tables
Base.metadata.drop_all(engine)
Base.metadata.create_all(engine)

db = Session()

# insert users
db.add_all([
  User(username='alesmonde0', email='nwestnedge0@cbc.ca', password='password123'),
  User(username='jwilloughway1', email='rmebes1@sogou.com', password='password123'),
  User(username='iboddam2', email='cstoneman2@last.fm', password='password123'),
  User(username='dstanmer3', email='ihellier3@goo.ne.jp', password='password123'),
  User(username='djiri4', email='gmidgley4@weather.com', password='password123')
])

db.commit()

db.close()
