Django Rest: Ajax Post Is Not Working, 400 Response

I am newbie to DRF and Ajax, my serializer code class CartItem(models.Model): cart_id = models.CharField('Cart ID', max_length=50) shop = models.ForeignKey(Shop) date

Solution 1:

HTTP 400 is Bad Request which means that Django is unable to understand the request.

Try adding:

  dataType: "json",
  contentType: "application/json"

Now Django will know that you are posting json This is what you are looking for.
