views.py

from flask import Flask
from exts import db
from models import *
import config

app = Flask(__name__)
app.config.from_object(config)
db.init_app(app)

@app.route('/')

    db.create_all() #根据模型创建表
    try:

    except Exception as e:
        print(e) 
    else:
        return '1'
    finally:
        return '0'


if __name__ == '__main__':
    app.run()

config.py

DEBUG = True
SQLALCHEMY_DATABASE_URI = 'sqlite:///test.db' #此为相对路径
SQLALCHEMY_TRACK_MODIFICATIONS = False

exts.py

models.py
