class SomeDerivedClass(SomeBaseClass):
    field10 = models.DateTimeField()
    field11 = models.ForeignKey(Business, blank=True)


class SomeDerivedClassForm(forms.ModelForm):
    class Meta:
        model = SomeDerivedClass
        exclude = ['field2']
        exclude = ['field10']
        exclude = ['field11']

渲染“SomeDerivedClassForm”时，即使我已将其设置为排除，field10 也会显示在网站上。在此之前，我在基类中有 field11，当时 field10 未显示在呈现的表单中，但 field11 出现了，即使它被排除在外。我意识到我的代码中一定有一些错误，但我没有看到它是什么。
您是否需要做一些特殊的事情才能将表单与派生类一起使用？

我不确定这是否那么简单。

而不是在您的代码中，exclude每次您想要向其中添加字段时，您都会覆盖列表。

 exclude = ['field2']
 exclude = ['field10']
 exclude = ['field11']

写：

 exclude = ['field2', 'field10', 'field11']
