Django bulk_create function example

Question

I\'m trying to understand bulk_create in Django

This was my original query I\'m trying to convert:

for e in q:
    msg = Message.objects.create(
                 


        

Answer 1

The second code in the question create a single object, because it pass a set with a Message object.

To create multiple objects, pass multiple Message objects to bulk_create. For example:

objs = [
    Message(
        recipient_number=e.mobile,
        content=batch.content,
        sender=e.contact_owner,
        billee=batch.user,
        sender_name=batch.sender_name
    )
    for e in q
]
msg = Message.objects.bulk_create(objs)

Answer 2

The Official Example:

class Entry(models.Model):
    blog = models.ForeignKey(Blog, on_delete=models.CASCADE)
    headline = models.CharField(max_length=255)
    body_text = models.TextField()
    pub_date = models.DateField()
    mod_date = models.DateField()

Now, to Bulk Create

Entry.objects.bulk_create([
        Entry(headline='This is a test'),
        Entry(headline='This is only a test'),
 ])
