Question

我在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，我收到此错误

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 'last_updated_by' clashes with related field 'User.itemlocator_company_related1'. Add a related_name argument to the definition for 'last_updated_by'.

我在使用Django 1.2。

Answer 1

您对related_by和last_updated_by的related_name是相同的，不应该是。

我可以看到你的类Meta是好的，只需更改related_name：）
