Say I have an image model with a many to one relationship to a product model as shown below:

```
   class Image(models.Model):
         product = ForeignKey(Product,on_delete=models.CASCADE,
        related_name='images'
        )
         original = ImageField(ulpoad_to='img/')

   class Product(models.Model):
        title = CharField(max_length=120)

        def get_images(self):
            return self.images.all()

        def get_primary_image(self):
            #return the first uploaded image in the queryset
            images = self.get_images()
            return images[0]

```

When trying to access **{{product.get\_primary\_image.url}}** on an image tag in a template it outputs an **IndexError** instead of the image, even after I add a couple more images to the database I still get the index error.
Where could I be going wrong? Please help I'm still a newbie at this.
