flask蓝图模式下，怎么使用pymongo

from flask import Flask
from flask-pymongo import PyMongo

app = Flask(__name__)
app.config.update(
    MONGO_HOST='localhost',
    MONGO_PORT=27017,
    MONGO_USERNAME='bjhee',
    MONGO_PASSWORD='111111',
    MONGO_DBNAME='flask'
)

mongo = PyMongo(app)

这是直接在入口文件里写的方法

现在加入里蓝图
home.py

from flask import Blueprint
import mysql.connector, logging
from flask_pymongo import PyMongo
import app

home = Blueprint('home', __name__, url_prefix='/home')
mongo = PyMongo(app)      // 这里应该怎么写 因为不存在app


@home.route('/test')
def move_tickets_to_mongo():

    res = mongo.db.acct_data_logs.find({})

这里会报错， 因为找不到app
