Type error to create and update my list in django rest framework

Question

I\'m trying to use my api to create and update products in a bundle. I did so:

model.py

class Business(models.Model):
    name = models.CharField(max         


        

Answer 1

The issue here is that you are posting a list to BundleProduct's product field yet it is an ForeignKey. To join Bundle to a Product, simply POST:

{
  "bundle": 2,
  "product" 1,
  "number": 1
}

You can repeat this:

{
  "bundle": 2,
  "product" 4,
  "number": 1
}

to add yet another product 4 to the same bundle and so on. Just make sure you do them one by one and not in a list as you had done earlier.
