[Feature] Get this works with ForeignKey

[AndrejGorodnij]

This feature will make life much simpler in e-commerce projects, where we need to create some constructions like:

class Image(models.Model):
    image = models.ImageField()

class Product(models.Model):
    name = models.CharField()

class ProductImage(models.Model):
    image = models.ForeignKey(Image)
    product = models.ForeignKey(Product)

Module can't access to Image fields using ForeignKey atributes.

AttributeError 'ForeignKey' object has no attribute 'get_internal_name'

Maybe I missed something in documentation?

It would be useful to support this for sure. It’s not currently possible, though you can work around the limitation by adding a property on one model that returns the image field on the related model. I just added that feature recently.

I’ll have a think about how best to support ForeignKey relations. Maybe we could use the double-underscore syntax Django uses for various related lookups.
