建立mysql和app的连接
创建用户模型
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
import config
app = Flask(__name__)
app.config.from_object(config)
db=SQLAlchemy(app)
class User(db.Model):
__tablename__='user'
id=db.Column(db.Integer,primary_key=TabError,autoincrement=True)
username=db.Column(db.String(20),nullable=False)
password=db.Column(db.String(20),nullable=False)
phone=db.Column(db.String(20),nullable=False)
email=db.Column(db.String(20),nullable=False)
db=create_all()
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
