Not sure what I'm doing wrong

I have also tried the following:

setting product to models.Product.objects.get(pk=1) setting product to models.Product.objects.filter(pk=1) setting product to models.Product.objects.filter(id=1) setting product to models.Product.objects.filter(id__exact=1) having Product.pk=1 in each set

products/emergency.py 
from . import models

def fix_25():
    product = models.Product.objects.get(id__exact=1)
    product.review_set.objects.bulk_create([
            Review(ratings=2),
            Review(ratings=3),
            Review(ratings=5)
            ])

You should use Review.objects.bulk_create([Review(...), Review(...)]) and for each Review specify rating and a product it is related to. 

from . import models


def fix_25():
    product = models.Product.objects.get(id=1)
    models.Review.objects.bulk_create([
        models.Review(rating=2, product=product),
        models.Review(rating=3, product=product),
        models.Review(rating=5, product=product),
    ])
