在 Django/Djongo 的另一个抽象 model 中是否可以有一个抽象 model ？

Question

我正在尝试在 meta 中添加一个带有 abstract=True 的 model class 到另一个抽象 class。例如，

class MainRecord(models.Model):
    date = models.DateTimeField(auto_now_add=True,null=True)
    X_data  = models.EmbeddedField(
        model_container=X,
        model_form_class= X_Form,
    )

class X(models.Model):
    HRCT = models.BooleanField()
    Y = models.EmbeddedField(
        model_container=Y,
        model_form_class=Y_Form,
    )

    class Meta:
        abstract = True

class Y(models.Model):
    Y_present = models.BooleanField()
    Location = models.EmbeddedField(
        model_container=Location,
        model_form_class=Location_Form,

        )     
    class Meta:
        abstract = True

在 Django 管理员中，我可以看到嵌入的字段及其对应的复选框。 I'm able to add/update values for the boolean field HRCT (Embedded from class X) but I'm not able to save the values/updates in the fields embedded from class Y to class X.
