bulk_create for Reviews with Product ID of 1

I'm not sure how to specify the product ID for each review.

I've tried the following, and none of them work: ... Review(product.id=1, rating=2) Review(product_id=1, rating=2) Review(product__id=1, rating=2) ...

Thanks in advance!

products/emergency.py 
from . import models

def fix_25():
    models.Review.objects.bulk_create([
        Review(product__id=1, rating=2),
        Review(product__id=1, rating=3),
        Review(product__id=1, rating=5),
    ])

Since you imported models you have to refer to models.Review. (Or you could do from .models import Review and then just refer to Review.) Also, product_id has only one underscore and you don't need the extra comma after the third item. (That shouldn't throw an error but delete just in case.) So it should be:

def fix_25():
    models.Review.objects.bulk_create([
        models.Review(product_id=1, rating=2),
        models.Review(product_id=1, rating=3),
        models.Review(product_id=1, rating=5)
    ])
