Why isn't get_job() working properly?

[jdstone]

get_job() doesn't seem to work properly. I have jobs stored in my jobstore of a SQLite job_scheduler.db file/database, but yet it returns nothing. Why doesn't get_job() return the job stored in my database file?

If I add a job during the same application process/execution and then call get_job(), it shows the job. But as soon as I stop the application process (via ctrl-c), and then start it again, get_job() returns None.

Here is my code:

__init__.py

from app.extensions import scheduler
from config import config
from flask import Flask
import os


def create_app(config_class=os.getenv('FLASK_ENV') or 'default'):
    # create and configure the app
    app = Flask(__name__, instance_relative_config=True)

    app.config.from_object(config[config_class])

    # ensure the instance folder exists
    try:
        os.makedirs(app.instance_path)
    except OSError:
        pass

    return app

basedir = os.path.abspath(os.path.dirname(__file__))


class Config(object):
    TESTING = False
    SECRET_KEY = os.environ.get('SECRET_KEY') or 'dev'
    SCHEDULER_API_ENABLED = True
    SCHEDULER_JOBSTORES = {'default': SQLAlchemyJobStore(url='sqlite:///job_scheduler.db')}

    DEBUG = True
    SQLALCHEMY_DATABASE_URI = 'sqlite:///' + os.path.join(basedir, 'app.db')

    SW_CONFIRM_API_URL = os.environ.get('SW_CM_API_URL')


config = {
    'development': DevelopmentConfig,
    'default': DevelopmentConfig,
}

checkin.py

from app import scheduler
from flask import Blueprint


bp = Blueprint('checkin', __name__, url_prefix='/')

def my_job():
    print('this is my job')


print(f"My JOB: {scheduler.scheduler.get_job('my_job10')}") # PRINTS `My JOB: None`

My friend and I figured this out. This occurred because I was registering the blueprint before initializing the scheduler. I should initialize the scheduler and then register the blueprint.
