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.

Answer 1

Using django.db.models.query.QuerySet.values results in more optimised queries for my use case.

import csv
from datetime import datetime

from django.http import HttpResponse

# Populate this list with your model's fields
# Replace MODEL with your model
fields = [f.name for f in MODEL._meta.fields]

# The following code will live inside your view
timestamp = datetime.now().isoformat()

response = HttpResponse(content_type="text/csv")
response[
    "Content-Disposition"
] = f"attachment; filename={timestamp}.csv"
writer = csv.writer(response)

# Write the header row
writer.writerow(fields)

# Replace MODEL with your model
for row in MODEL.objects.values(*fields):
    writer.writerow([row[field] for field in fields])

return response
