Django序列化程序显示相关模型的布尔字段

我有两个模型: App &安培; AppVersion

我正在尝试序列化 以及来自 应用程序 模型。无法在序列化程序中显示相关字段。

目标

我的目标是让API响应包含如下相关字段:

[
    {
        "app_version_uuid": "61ee8efa-f79e-4fcd-a6ea-4a33544442e1",
        "app_version_name": "Test app version",
        "version_code": 2,
        "version_name": "0.2",
        "auto_start": True   # related field
    }
]

# models.py

class App(models.Model):
    app_uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, db_index=True)
    app_name = models.CharField(max_length=100)
    package_id = models.CharField(max_length=100, unique=True, null=True, blank=True, editable=False)
    auto_start = models.BooleanField(default=False)  


class AppVersion(models.Model):
    app_version_uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, db_index=True)
    app_uuid = models.ForeignKey(App, on_delete=models.CASCADE, related_name='app_versions')
    app_version_name = models.CharField(max_length=100)
    version_name = models.CharField(blank=True, null=True, max_length=100, editable=False)
    version_code = models.IntegerField(blank=True, null=True, editable=False)

串行器

# serializers.py

class AppVersionSerializer(serializers.ModelSerializer):
    auto_start = serializers.SlugRelatedField(read_only=True, slug_field='auto_start')

    class Meta:
        model = AppVersion
        fields = ('app_version_uuid', 'app_version_name', 'version_code', 'version_name', 'auto_start')

我试过的

我试着用 SlugRelatedField() serializers.py SerializerMethodField() 这样地:

# serializers.py

class AppSerializer(serializers.ModelSerializer):
    class Meta:
        model = App
        fields = ('auto_start')

class AppVersionSerializer(serializers.ModelSerializer):
    auto_start = serializers.SerializerMethodField(read_only=True)

    def get_auto_start(self, model):
        return AppSerializer(model).data

    class Meta:
        model = AppVersion
        fields = ('app_version_uuid', 'app_version_name', 'version_code', 'version_name', 'auto_start')

这个 不显示 auto_start 在回应中。

使用 自动启动 如图所示:

"auto_start": {}

自动启动 在我的回答中?
