如何使用Django Rest框架在其他表中插入外键？

我正在使用Django REST框架，我一直在将外键数据插入另一个表中。 请参考以下场景：
如下面代码所示，我想在

模板

表中插入数据，并使用单个post请求在

模板

表中插入外键关系。
我尝试了一些解决方案，但没有达到预期效果，非常感谢您的帮助

Django Rest框架中很少有与Foreignkey相关的问题，但这些问题都与数据插入无关，它们主要关注数据获取，因此请在标记“复制”之前检查整个场景。

序列化程序和创建过程中几乎没有问题，因此请相应地进行更改

class TemplateOwnerSerializer(serializers.ModelSerializer):
    class Meta:
        model = TemplateOwners  
        fields = ("gid", "uid", "date")

class TemplateSerializer(serializers.ModelSerializer):
    owners_data = TemplateOwnerSerializer(many=True)

    class Meta:
        model = Template
        fields = ("uuid", "name", "hypervisor", "download_url", "size", "date", "owners_data")

    def create(self, validated_data):
        owners_data = validated_data.pop('owners_data')
        template = Template.objects.create(**validated_data)
        for owner_data in owners_data:
            TemplateOwners.objects.create(template_uuid=template, **owner_data)
        return template

发布stacktrace以及您试图插入的字段？@Exprator，我想在template_owners表中插入uuid、gid、uid、date。感谢您的回答，这对我也有帮助，但有一个问题：我如何对多个表执行相同的操作。我的意思是我需要在另一个表中插入相同的外键和一些其他数据。我用同样的方法做了，但它只在第一个表中插入数据，而不是在第二个表中。等待您的回复。
