All inline models need to have a ForeignKey pointing back to the base
model.
In your case you need to declare a ForeignKey field from Gallery model
to Business model, what you've did instead is you've created foreign
key to parent class (Directory).
Try this:
class Directory(models.Model):
name = models.CharField(max_length=60)
class Business(Directory):
anyfield = models.CharField(max_length=60)
class Gallery(models.Model):
directory = models.ForeignKey(Business),
pic = models.ImageField(upload_to='pics')
