Does Django out of the box have a similar functionality to the "nested attributes" mechanism from Ruby on Rails?

Question

Django

Good time of the day! Can you please tell me if there is a possibility in Django when receiving parameters from the client in the conditionally following format ...

product_params = {
  'title': 'Название',
  'properties': {
    '1': {'title': 'свойство 1'},
    '2': {'title': 'свойство 2'},
    '3': {'title': 'свойство 3'},
  }
}

...do two actions...

product = Product(product_params)
product.save()

...and automatically save both product and properties.

At the same time, do not engage in independent iteration of all properties, first opening a transaction, validate the product, save the product, take the primary-key product, and then independently save all properties in turn with validation, and so on.

Tell me, please, where can I read about this method? Unfortunately, I couldn't google it or find it in the documentation.

Answer 1

the closest in meaning, not the fact that https://docs.djangoproject.com/en/3.1/topics/seria...

If the pk attribute in the serialized data doesn't exist or is null, a new instance will be saved to the database.
