在Django的loaddata中设置外键

Question

我设置了两个类，其中用户可能具有多个访问键。

class User(models.Model):
    first_name = models.CharField(max_length=50)
    middle_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    email = models.EmailField()
    password = models.CharField(max_length=50)
    birthday = models.DateField()

    def __str__(self):
        return self.first_name+" "+self.last_name

class pets(models.Model):
    user = models.ForeignKey('User')
    type = models.CharField(max_length=50)
    color = models.CharField(max_length=50)

    def __str__(self):
        return self.type

我正在尝试通过一个看起来像json文件的loaddata使用数据预加载表：

[
{
    "fields": {
        "first_name": "John",
        "last_name": "Doe",
        "middle_name": "G",
        "birthday": "1900-07-21",
        "password": "goforit123",
        "email": "John.Doe@gmail.com"
        },
        "model": "account_data.user",
    "pk": 1
},
{
    "fields": {
        "user": "????"
        "type": "dog",
        "color": "blue"
    },
    "model": "account_data.pets",
    "pk": 1
}
]

我要为宠物课程向用户添加什么？

非常感谢！

您只需要使用要链接的对象的de pk：

[
{
    "fields": {
        "first_name": "John",
        "last_name": "Doe",
        "middle_name": "G",
        "birthday": "1900-07-21",
        "password": "goforit123",
        "email": "John.Doe@gmail.com"
    },
    "model": "account_data.user",
    "pk": 1  // This is the pk you have to use
},
{
    "fields": {
        "user": 1,  // Use the pk, in this case you're referencing to John Doe
        "type": "dog",
        "color": "blue"
    },
    "model": "account_data.pets",
    "pk": 1
}
]
