Because i can't find related post here, so i post this example. maybe someone else need.
Sometimes, you just want to use the useful models of django without thinking any sql statement.
Maybe you want to run a script to know which user's birthday in your database is today,
this little job should not run in the view.py. It should run in the cron table of linux os every day,
so that your users can receive birthday card from your system.
this example is so easy, all you know is loading the settings.py correctly.
Your script must place in your django project's directory.
script example:
1 #!/usr/bin/env python
2 # -*- coding: utf8 -*-
3
4 import settings
5 from django.core.management import setup_environ
6 setup_environ(settings)
7 # before do something else,
8 # the there lines above here is your first operation.
9
10 from django.db.models import get_model
11 from datetime import date
12
13 if __name__ == '__main__':
14
15 # the 'tmp' is your project's name,
16 # and this script must place in the 'tmp' directory.
17 # the 'person' is your model's name.
18 Person = get_model('tmp', 'person')
19
20 # when you get the model,
21 # you can use it just like you use it in the view.py
22 P = Person(name='hoamon', birth=date(1977, 10, 18))
23 P.save()
24
25 for p in Person.objects.all():
26 if p.birth == date(1977, 10, 18):
27 print p.name
28
29 for p in Person.objects.filter(birth=date(1977, 10, 18)):
30 print p.name
now you can put /somepath/tmp/birthday.py in the cron table.
