How do I use a dictionary to update fields in Django models?

Question

Suppose I have a model like this:

class Book(models.Model):
    num_pages = ...
    author = ...
    date = ...

Can I create a dictionary,

Answer 1

Here's an example of create using your dictionary d:

Book.objects.create(**d)

To update an existing model, you will need to use the QuerySet filter method. Assuming you know the pk of the Book you want to update:

Book.objects.filter(pk=pk).update(**d)
