How to check ImageField is empty

Question

I found that the ImageField’s name is
u”, so is there any better way to do
it ?

Actually, it looks like that’s exactly how this class evaluates bool(), so the better way is to just test its bool() by calling if p.avatar

ImageFieldFile subclasses File, which defines:

def __nonzero__(self):
    return bool(self.name)

So the better way is indeed:

if not p.avatar:
   print "I don't exist"

bool(p.avatar) is False
