django-bulk-copy 0.1.3

Faster way to create your models in Django

Django Bulk Copy

Create your mass data in a faster way with the COPY command.

Currently it supports only the Postgresql database.

Install

pip install django-bulk-copy

Usage

class TestModel(models.Model):
    integer_field = models.IntegerField(null=True)
    char_field = models.CharField(max_length=32, null=True)
    boolean_field = models.BooleanField(default=False)
    datetime_field = models.DateTimeField(null=True)
    json_field = models.JSONField(null=True)

from bulk_copy import BulkCopy

objects = [
    TestModel(
        integer_field=i,
        char_field=str(i),
        boolean_field=bool(i % 2),
        datetime_field=timezone.now(),
        json_field={i: f"{i:>09}"},
    )
    for i in range(1000)
]

BulkCopy(objects)

BulkCopy only uses the initial time of the transaction if your model has a date/datetime field with auto_now=True.

Additional

If you need to create your models from a csv file, django-postgres-copy could be a better alternative.
