Re: Bulk import of data

>>> import csv
>>> data = csv.reader(open('/path/to/csv', 'r'), delimiter=';')
>>> for row in data:
>>> category = Category.objects.get_or_create(name=row[0])
>>> sub_category = SubCategory.objects.get_or_create(name=row[1],
>>> defaults={'parent_category': category})
>>> product = Product.objects.get_or_create(name=row[2],
>>> defaults={'sub_category': sub_category})

There are few potential problems with the cvs as used here.

Firstly, the file should be opened in binary mode. In Unix-based
systems, the binary mode is technically similar to text mode.
However, you may once observe problems when you move
the code to another environment (Windows).

Secondly, the opened file should always be closed -- especially
when building application (web) that may run for a long time.
You can do it like this:

...
f = open('/path/to/csv', 'rb')
data = csv.reader(f, delimiter=';')
for ...
...
f.close()

Or you can use the new Python construct "with".
