django dump to csv

“`
import csv
from django.db.models.loading import get_model

def dump(qs, outfile_path):
“””
Takes in a Django queryset and spits out a CSV file.

Usage::

>> from utils import dump2csv
>> from dummy_app.models import *
>> qs = DummyModel.objects.all()
>> dump2csv.dump(qs, ‘./data/dump.csv’)

Based on a snippet by zbyte64::

http://www.djangosnippets.org/snippets/790/
“””
model = qs.model
writer = csv.writer(open(outfile_path, ‘w’))

headers = []
for field in model._meta.fields:
headers.append(field.name)
writer.writerow(headers)

for obj in qs:
row = []
for field in headers:
val = getattr(obj, field)
if callable(val):
val = val()
if type(val) == unicode:
val = val.encode(“utf-8”)
row.append(val)
writer.writerow(row)
