我正在使用烧瓶python3
。
迁移脚本工作没有错误。主应用程序也运行良好。当我运行迁移时,我正在使用postgresql
一切运行正常,但是当我进入postgres
shell 时,我看不到任何正在创建的表。
模型.py
from imports import db
from datetime import datetime
from sqlalchemy import ForeignKey
from sqlalchemy.orm import relationship
class UserInfo(db.Model):
__tablename_ = 'user_info'
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True)
email = db.Column(db.String(80), unique=True)
password = db.Column(db.String(100), nullable=False)
posts = relationship('UserPosts', backref='posts')
def __init__(self, username, email, password):
self.username = username
self.email = email
self.password = password
def __repr__(self):
return '{}-{}'.format(self.username, self.email)
如您所见,我在那里有两个表,但我只user_info
在我的数据库中看到,因为我手动创建了它,但另一个表我看不到。
export DATABASE_URL="postgresql:user:password@localhost/registration"
tail /var/log/apache2/error.log

我不知道我是否以正确的方式设置了与数据库的连接,或者根本没有创建任何内容。
谢谢。
