在两种型号的Django中都使用manytoman字段

我有两个模型，分别名为

Profile

和

conference

。我的要求是很多人可能会卷入一场争论，而一个人可能会有多场争论。话虽如此，我觉得我应该在两个模型中都使用

ManyToMany

字段，但我猜这违反了

ManyToMany

字段文档，因为它应该只在模型中使用

我的模型如下：

class Profile(models.model):
    name = models.CharField(max_length=200)
    Controversy = models.ManyToManyField(Controversy) # As one person can have multiple controveries


class Controversy(models.Model):
    year = models.Datefield()
    other_people_involved = models.ManytoManyField(profile) # As multiple people can be involved in a controversy
    description = models.TextField()

这显然会带来错误。 我无法理解如何处理这种情况

您可以尝试以下方法：

创建另一个模型来存储

个人

和

争议

连接

class Profile(models.model):
    name = models.CharField(max_length=200)

class Controversy(models.Model):
    year = models.Datefield()
    description = models.TextField()

class PeopleInvolved(models.Model):
    controversy = models.ManyToManyField(Controversy)
    person = models.ManytoManyField(profile)

因此，要列出一个人的争议，请执行以下操作：

controversies = [i.controversy for i in PeopleInvolved.objects.filter(person=[profile_id])] #pass the profile id of the person.

要列出与争议有关的人员，请执行以下操作：

peoples = [i.person for i in PeopleInvolved.objects.filter(controversy=[controversy_id])] #pass the controversy id.

您可以这样尝试：

创建另一个模型来存储

个人

和

争议

连接

class Profile(models.model):
    name = models.CharField(max_length=200)

class Controversy(models.Model):
    year = models.Datefield()
    description = models.TextField()

class PeopleInvolved(models.Model):
    controversy = models.ManyToManyField(Controversy)
    person = models.ManytoManyField(profile)

因此，要列出一个人的争议，请执行以下操作：

controversies = [i.controversy for i in PeopleInvolved.objects.filter(person=[profile_id])] #pass the profile id of the person.

要列出与争议有关的人员，请执行以下操作：

peoples = [i.person for i in PeopleInvolved.objects.filter(controversy=[controversy_id])] #pass the controversy id.
