from flask import Flask
from flask_session import Session
from import db
from . import search_bp
from flask_script import Manager
from flask_migrate import Migrate, MigrateCommand
def create_app():
app = Flask(__name__)
_object('pmentConfig')
er_blueprint(search_bp)
Session(app)
_app(app)
app = Manager(app)
Migrate(app, db)
_command('db', MigrateCommand)
return app
总结
对比django,flask最后选用自由度较大的flask。
集合flask-script,flask_sqlalchemy,flask-migrate加快开发。
写一个小demo深化了对es接口的理解。
