Question

我有4个用户通过点击一个Submit按钮提交的表单。表格是：

Person Form - 将保存为人员模型
Address Form - 将保存到地址模型
Email Form - 将保存为电子邮件模型
Phone Form - 将保存到手机型号。

因此，Person可以包含多个Addresses，Emails和Phone个数字。所以，我在人物模型中做到了这一点：

class Person(models.Model):
    first_name = models.CharField(max_length=99)
    middle_name = models.CharField(max_length=99, blank=True, null=True)
    last_name = models.CharField(max_length=99, blank=True, null=True)
    address = GenericRelation('Address')
    phone = GenericRelation('Phone')
    email = GenericRelation('Email')

我有这3行以及Address，Phone和Email

content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
object_id = models.PositiveIntegerField()
content_object = GenericForeignKey('content_type', 'object_id')

现在，当我从用户那里收到表单时，如何在我的视图中正确地将数据保存到这些模型？这就是我到目前为止所做的。

 if request.method == 'POST':
        if person_form.is_valid() and address_form.is_valid() and email_form.is_valid() \
                and phone_form.is_valid():

            address = address_form.save()
            email = email_form.save()
            phone = phone_form.save()

            person = person_form.save(commit=False) #This person model has a generic foreign key relation with Address, Email and Phone
            person.address = (address)  #This is where I need help. Am I thinking right? Is this the right way to save?

你需要在模型中设置内容对象，其中定义了GFK，我修改了代码，

 if request.method == 'POST':
                if person_form.is_valid() and address_form.is_valid() and email_form.is_valid() \
                        and phone_form.is_valid():

                person = person_form.save()

                address = address_form.save(commit=False)
                address.content_object = person
                address.save()
                email = email_form.save(commit=False)
                email.content_object = person
                email.save()
                phone = phone_form.save(commit=False)
                phone.content_object = person
                phone.save()

但我有一个严重怀疑？为什么你的模型中使用Generic Foreign Key？这些模型可以引用除Person之外的任何其他模型。

如何从我的视图中设置django通用外键？
