django-tastypie: Posting to a Resource having ManytoMany field with through relationship

Question

I\'m working on a API for a project and I have a relationship Order/Products through OrderProducts like this:

In models.py

class Product(models.Model         


        

Answer 1

Since you needed the manytomany field only for listing, a better solution is to add readonly=True on OrderResource's products field. This removes the need of overriding save_m2m method. For completeness:

class OrderResource(ModelResource):
    products = fields.ToManyField('order.api.ProductResource', products, 
                                  readonly=True, full=True)

    class Meta:
        queryset = Order.objects.all()
        resource_name = 'order'
