Validating django models on runserver command

Question

I want to create some custom validation on models when I do python manage.py runserver command. Can I do this somehow?

I'm write some program (with windows) that creates django web app. User can make some logic errors which django cant see. But they will later be revealed while executing django app. — milandjukic88, Jan 21 '14 at 17:28
for example, I create readOnly field (readOnly is field attribute) without default value and cant be empty. User cannot enter value and while submiting form.... error... (no data) — milandjukic88, Jan 21 '14 at 17:30
And why would you choose to do some weird thing as that? Can't you just (from your code) validate this things simply don't happen? — finiteautomata, Jan 21 '14 at 17:31
Sorry I didnt be clear enough. That program (with windows) is not written by me. My assign is just to create django app from data from that program. Because I'm not sure how they do validation, i want to make another protection. I hope you understand because my english is bad :) — milandjukic88, Jan 21 '14 at 17:35

Well, the problem in fact is that you want to run some custom code when your server starts up.

Two possibilities:

Use wsgi.py as suggested by this post. This seems to be the more elegant solution.
Put all your code inside some __init__.py file. Be warn that this code will be executed any time you import that package (for example, when you run a django command)
