如何在 Django-admin 内联表单中显示子类模型？

Question

我在 models.py 中得到了一些这样的模型：

class QuestionPackage(models.Model):
    """Question Package"""


class Question(models.Model):
    question_package = models.ManyToManyField(QuestionPackage, blank=True)
    name = models.CharField(max_length=128)
    answer = models.TextField()


class Reading(Question):
    """Reading Question"""


class Writing(Question):
    """Writing Question"""

(读和写有一些区别，我忽略了。)

并在 admin.py 中：

class ReadingInline(admin.TabularInline):
    model = Reading.question_package.through


class WritingInline(admin.TabularInline):
    model = Writing.question_package.through


class QuestionPackageAdmin(admin.ModelAdmin):
    inlines = [
        ReadingInline, WritingInline,
    ]

我发现在question package管理页面的内联表单中，Reading和Writing都显示为Question，我无法区分它们。他们没有编辑按钮。

在这种情况下，如何让管理员显示子类模型？

Answer 1

那么在这种情况下，超级 class 问题应该是抽象的 class:

class Question(models.Model):
    question_package = models.ManyToManyField(QuestionPackage, blank=True)
    name = models.CharField(max_length=128)
    answer = models.TextField()

    class Meta:
        abstract = True
