python flask app.py创建

from flask import Flask
from exts import db
from models.models import UserModel
import config
from blueprints.qa import bp as qa_bp
from blueprints.auth import bp as auth_bp
from flask_migrate import Migrate

app = Flask(__name__)

# app配置文件
app.config.from_object(config.DevelopmentConfig)

# 保证初始化完成后，再传入参数app进行绑定
db.init_app(app)

migrate = Migrate(app, db)  #数据库迁移映射


# 注册蓝图
app.register_blueprint(qa_bp)
app.register_blueprint(auth_bp)

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

在pycharm中引入库时，会出现Cannot find reference 'XXX' in '_init_.py'的报错字样

在保证库（尤其是第三方库）的安装完成并在pycharm中引入成功后，执行如下操作即可解决问题：
File→Settings→Editor→Inspections→在右侧框中选择python → Unresolved references,
将Unresolved references后的“√”勾掉即可
