问题描述

我有 2 个表用户和域之间的多对多关系.我在 Domains 类中定义了这种关系.因此，在管理界面中，当我查看域时，我会看到用户.但是当我查看用户时，我看不到域.我怎样才能做到这一点.

推荐答案

我知道这是一个较旧的线程，但这是在 google 上出现的第一个结果，我认为需要一个更好的答案.

I know that this is an older thread, but this was the first result that came up on google and I thought a better answer was necessary.

通过 这个 django 错误报告，我找到了拥有 ManyToManyField 的最佳方式出现在两个模型上:

Via this django bug report I found the best way to have your ManyToManyField show up on both models:

class Test1(models.Model):
    tests2 = models.ManyToManyField('Test2', blank=True)

class Test2(models.Model):
    tests1 = models.ManyToManyField(Test1, through=Test1.tests2.through, blank=True)

我自己测试过，对结果非常满意.

I have tested it myself and was very pleased with the results.
