Django-admin动态过滤ForeignKey字段

Question

I have a model:

class Foo(models.Model):
    pass
class Bar(models.Model):
    foo = Models.ForeignKey(Foo)
class Last(models.Model):
    bar = Models.ForeignKey(Bar)

When I want to create a new instance of Last , bar field in djando-admin contains all instances of Bar. How to filter it by relationship with Foo?

Thanks

Admin类中的raw_id_fields = ('bar',)
