python - 无法在 __init__ 处向 ModelForm 添加字段

Question

我对 ModelForm 有疑问。字段 test1 显示，但 test2- 未显示。使用 base_fields 没有帮助。

# models.py
class Country(models.Model):
    name = CharField(max_length=100)

# admin.py
class CountryAdminForm(ModelForm):
    test1 = forms.CharField('test1')

    def __init__(self, *args, **kwargs):
        super(CountryAdminForm, self).__init__(*args, **kwargs)
        self.fields['test2'] = forms.CharField('test2')

    class Meta:
        model = Country

class CountryAdmin(admin.ModelAdmin):
    form = CountryAdminForm

admin.site.register(Country, CountryAdmin)

谢谢。
