相关疑难解决方法(0)

我似乎无法弄清楚为什么我对db.create_all()的调用不起作用.

我有一个包含以下init的应用包:

from flask import Flask
from config import config
from flask.ext.sqlalchemy import SQLAlchemy

# create the database object
db = SQLAlchemy()

# this function is the application factory
def create_app(environment):
    app = Flask(__name__)
    app.config.from_object(config[environment])

    db.init_app(app)

    from bp_root import bp_root
    from bp_aws import bp_aws

    app.register_blueprint(bp_root, url_prefix='/')
    app.register_blueprint(bp_aws, url_prefix='/aws')

    return app

然后我在app包里面有models.py:

from datetime import datetime
from . import db

class MyTestClass(db.Model):
    __tablename__ = 'mytesttable'
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(64), nullable=False, unique=True, index=True)
    username = db.Column(db.String(64), nullable=False, unique=True, index=True) …
