Exporting items from a model to CSV Django / Python

Question

I\'m fairly new to django and Python and want to be able to export a list of items in my model i.e products. I\'m looking at the documentation here - https://docs.djangoproject.

Here is a potential solution, based on @tomasz-gandor 's answer, but updated to 2020:

"""
 Prints CSV of all fields of a model.
"""

import csv
from django.core.management.base import BaseCommand, CommandError


class Command(BaseCommand):
    help = ("Output the specified model as CSV")


    def add_arguments(self, parser):
        parser.add_argument('model',
                            nargs=1,
                            type=str,
                            help='Model name to export, like  or "members.Member"')
        parser.add_argument('outfile',
                            nargs=1,
                            type=str,
                            help='Save path, like  or "/data/members.csv"')


    def handle(self, *app_labels, **options):
        from django.apps import apps
        app_name, model_name = options['model'][0].split('.')
        model = apps.get_model(app_name, model_name)
        field_names = [f.name for f in model._meta.fields]
        writer = csv.writer(open(options['outfile'][0], 'w'), quoting=csv.QUOTE_ALL, delimiter=',')
        writer.writerow(field_names)
        for instance in model.objects.all():
            writer.writerow([str(getattr(instance, f)) for f in field_names])

Can easily be used with:

python manage.py model2csv members.Member /data/members_export.csv
