访问 ForeignKey 模型属性

Question

I'm trying to access to the attribute of the model through a ForeignKey, like this :

class Foo(models.Model):
    name = models.CharField('Name', max_length=64)

class FooImage(models.Model):
    model = models.ForeignKey('Foo', related_name='image')
    image = models.ImageField(upload_to='goo/{}/'.format(HERE))

I want the name attribute of Foo where the HERE is. I tried many things as :

self.model.name
model.name
self.name

But it doesn't work.. So, how can I do that ?

Refer to django documenation at https://docs.djangoproject.com/en/1.8/ref/models/relations/ . Here you'll come to know in depth about how related fields can be accessed.
