在管理模型中可以继承吗？
例如，请考虑以下内容，
档案： models.py
class AbstractModel ( models.Model ):
# Meta Information common to all classes
author = models.ForeignKey(auth.models.User , null = False ,related_name="%(class)s_related_author" ) # The user who created
editor = models.ForeignKey(auth.models.User , null = True,related_name="%(class)s_related_editor" ) # The user who last edited
created_at = models.DateTimeField(auto_now_add = True) # Create Time
edited_at = models.DateTimeField(auto_now = True) # Modify Time
class Meta:
abstract = True
class Topic( AbstractModel ):
name = models.CharField(max_length = NameMaxLength , unique = True)
version_number = …
