Challenge 1 / 1

I want to make the following request:

PATCH /api/categories/5

{
    "products": [
        "/api/products/2",
        { "name": "Toothpaste", "price": 4.99 }
    ]
}

Assume this operation uses the denormalization group called category:write.

Which of the following is not required to make this work?

The Category.products property needs to have Valid constraint on it.

The name and price properties in Product need to be in the category:write group.

The Category.products property needs to have cascade: ['persist'] on it.

The Category.products property needs to have the category:write group.

All of these are needed.
