Django / South：在ManyToMany到自我关系中，为中间模型设置related_name参数的正确方式是什么？ [英] Django/South: What is the proper way to set related_name arguments for the intermediate model on a ManyToMany to self relation?

问题描述

这与问题我昨天问过，将一个从ForeignKey转变为Self到ManyToManyField到自己的变化，但是由于我暂时只是由于时间限制原型制作了一个应用程序， ve决定放下相关的表并重新设置迁移历史记录。

This is related to a question I asked yesterday about migrating a change from a ForeignKey to self to a ManyToManyField to self, however because I'm only prototyping an app for the time being/due to time constraints, I've decided to just drop the relevant tables and reset the migration history.

这些是相关的模型/字段：

These are the relevant models/fields:

class Person(models.Model):
    nominator = models.ManyToManyField('self', symmetrical=False,                
            verbose_name=_('nominator'), through='Nomination', null=True,        
            blank=True)


class Nomination(models.Model):                                                  
    nominee = models.ForeignKey(Person)                                          
    nominator = models.ForeignKey(Person)

但是，这甚至不会生成初始迁移：

However, this doesn't even generate an initial migration:

$ ./manage.py schemamigration nominations --initial
CommandError: One or more models did not validate:
nominations.nomination: Accessor for field 'nominee' clashes with related field 'Person.nomination_set'. Add a related_name argument to the definition for 'nominee'.
nominations.nomination: Accessor for field 'nominator' clashes with related field 'Person.nomination_set'. Add a related_name argument to the definition for 'nominator'.

我按照说明添加一个 related_name 提名模型中 nominator 和 nominee 字段的参数，如下所示：

I followed the instructions to add a related_name argument to the nominator and nominee fields on the Nomination model, like so:

class Nomination(models.Model):                                                  
    nominee = models.ForeignKey(Person, related_name=_('nominator'))             
    nominator = models.ForeignKey(Person, related_name=_('nominee'))  

这给了我一个不同的错误：

That gave me a different error:

$ ./manage.py schemamigration nominations --initial
CommandError: One or more models did not validate:
nominations.nomination: Accessor for field 'nominee' clashes with m2m field 'Person.nominator'. Add a related_name argument to the definition for 'nominee'.
nominations.nomination: Reverse query name for field 'nominee' clashes with m2m field 'Person.nominator'. Add a related_name argument to the definition for 'nominee'.

我不知道该怎么做。我感觉到我忘记了一些 Person 模型，但是我不知道这可能是什么，因为Django / South文档不是很可靠来到这种关系。

I'm not sure what to do from this point. I get the feeling that I've forgotten something the Person model, but I'm not sure what that could be since both the Django/South docs are not terribly forthcoming when it comes to this kind of relation.

推荐答案

只需使用字段名称以外的其他名称即可。有人像person_nominator和person_nominee。

Just use different names other than the fields names. Something like person_nominator and person_nominee.

我将此评论移到一个答案，以便问题不再没有答案。

I move this comment to an answer so that the question is no longer without an answer.
