我想知道如何正确创建用于创建此 Django 模型的突变：

class Company(models.Model):

    class Meta:
        db_table = 'companies'
        app_label = 'core'
        default_permissions = ()

    name = models.CharField(unique=True, max_length=50, null=False)
    email = models.EmailField(unique=True, null=False)
    phone_number = models.CharField(max_length=13, null=True)
    address = models.TextField(max_length=100, null=False)
    crn = models.CharField(max_length=20, null=False)
    tax = models.CharField(max_length=20, null=False)
    parent = models.ForeignKey('self', null=True, on_delete=models.CASCADE)
    currency = models.ForeignKey(Currency, null=False, on_delete=models.CASCADE)
    country = models.ForeignKey(Country, null=False, on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

如您所见，共有三个外键。对于模型Currency、Country和Parent(self)。公司 DjangoObjectType看起来非常简单，如下所示：

class CompanyType(DjangoObjectType):
    class Meta:
        model = Company

最后我的变异类 …
