[Django]-Bulk create model objects in django

as of the django development, there exists bulk_create as an object manager method which takes as input an array of objects created using the class constructor. check out django docs

name = request.data.get('name')
period = request.data.get('period')
email = request.data.get('email')
prefix = request.data.get('prefix')
bulk_number = int(request.data.get('bulk_number'))

bulk_list = list()
for _ in range(bulk_number):
    code = code_prefix + uuid.uuid4().hex.upper()
    bulk_list.append(
        DjangoModel(name=name, code=code, period=period, user=email))

bulk_msj = DjangoModel.objects.bulk_create(bulk_list)

worked for me to use manual transaction handling for the loop(postgres 9.1):

from django.db import transaction
with transaction.atomic():
    for item in items:
        MyModel.objects.create(name=item.name)

in fact it’s not the same, as ‘native’ database bulk insert, but it allows you to avoid/descrease transport/orms operations/sql query analyse costs

Here is how to bulk-create entities from column-separated file, leaving aside all unquoting and un-escaping routines:

SomeModel(Model):
    @classmethod
    def from_file(model, file_obj, headers, delimiter):
        model.objects.bulk_create([
            model(**dict(zip(headers, line.split(delimiter))))
            for line in file_obj],
            batch_size=None)

Using create will cause one query per new item. If you want to reduce the number of INSERT queries, you’ll need to use something else.

I’ve had some success using the Bulk Insert snippet, even though the snippet is quite old.
Perhaps there are some changes required to get it working again.

On my django 1.3 app, I have experienced significant speedup.

The easiest way is to use the create Manager method, which creates and saves the object in a single step.

for item in items:
    MyModel.objects.create(name=item.name)
