Can't create review as bulk

Hi there,

I cannot succeed to create some data in bulk but when I test it in the shell it works perfectly.

Here is attached my code.

Thanks for your response

products/emergency.py 
from . import models

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

You are really close. Two fixes needed:

  • Since the import was for models, the Review objects need to be referred to as models.Review
  • The parameter should be product_id instead of product

Post back if you have more questions. Good luck!!

Hi Chris got it, thanks.

Now, what is the difference between:

  • product_id
  • product.id
  • product_pk
  • product.pk

thanks for the explanation, it's not very clear on the video.
