python - Django - 抽象基类模型破坏 syncdb

Question

我的 models.py 中有这个:

class AuditableTable(models.Model):
    class Meta:
        abstract = True
        created_by = models.ForeignKey(User,blank=True,
        related_name="%(app_label)s_%(class)s_related1")
        last_updated_by = models.ForeignKey(User,blank=True,
        related_name="%(app_label)s_%(class)s_related1")

class Company(AuditableTable): pass

我相信我正在关注 instructions related to abstract models mentioned here .

但是当我运行 manage.py syncdb 时出现这个错误:

Error: One or more models did not validate:
ItemLocator.company: Accessor for field 'created_by' clashes with related field 'User.itemlocator_company_related1'. Add a related_name argument to the definition for 'created_by'.                                                                                       
ItemLocator.company: Reverse query name for field 'created_by' clashes with related field 'User.itemlocator_company_related1'. Add a related_name argument to the definition for 'created_by'.                                                                             
ItemLocator.company: Accessor for field 'last_updated_by' clashes with related field 'User.itemlocator_company_related1'. Add a related_name argument to the definition for 'last_updated_by'.                                                                             
ItemLocator.company: Reverse query name for field 'last_updated_by' clashes with related field 'User.itemlocator_company_related1'. Add a related_name argument to the definition for 'last_updated_by'.   

我正在使用 Django 1.2。

Answer 1

created_by 和 last_updated_by 的 related_name 相同，但不应该相同。

据我所知，您的 class Meta 没问题，只需更改 related_name :)
