Regular, timed editing of a text file in Django

Question

Every time a certain table is saved/created in my application I want a text file on the server to be updated in tandem. I've been thinking that this could be either done each time the model's save() method is called, or perhaps just achieved as a regular job every hour, for example.

I can't see a standard Django-y way of actually implementing this, does anyone have a suggestion, or perhaps a better idea?

Thanks very much

by table saved do you mean insert/update record record? have you looked into django's provided [logging](https://docs.djangoproject.com/en/dev/topics/logging/) functionality, have you considered your databases logging functionality? — T I, Jan 03 '12 at 18:22

Maybe you can use the Django signals to write the model changes in your file.

This is exactly what signals are for. – joel3000 Jan 03 '12 at 19:36
This was spot on, thank you. To anyone else who is thinking of something similar I can highly recommend this. Really easy to implement. – R.B. Jan 04 '12 at 12:11

If you're looking for revision support for your models you could always use django-reversion

https://github.com/etianen/django-reversion

This will keep track of all model changes.

If you want it to run every hour instead of on change, I recommend using django-celery to set up a task
