同步我的数据库和从 API 接收的数据的最有效方法是什么？

Question

I'm storing user's data and articles using the Pocket API into a SQLite Database using Django Framework. How can I efficiently maintain consistency between the database and the data received from the API? I'm planning to update the database once every 24 hours.

Should be simple with chron jobs . If you already have a model with logic to fetch data from the Pocket API and parse it, it's as simple as:

class MyCronJob(CronJobBase):
    RUN_EVERY_MINS = 120 # every 2 hours

    schedule = Schedule(run_every_mins=RUN_EVERY_MINS)
    code = 'my_app.my_cron_job'    # a unique code

    def do(self):
        data = fetch_your_data()
        save_data(data)

If you don't have the parsing logic yet, I'd suggest Django Rest Framework serializers . Using the serializers is simple and saving the data shrinks down to:

def save_data(json_data):
    serializer = YourPocketDataSerializer(json_data)
    serializer.save()
