无法在__init__处向ModelForm添加字段

Question

我有ModelForm的问题.显示字段"test1",但"test2" - 不显示.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.

解决了!

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

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

    class Meta:
        model = Country
        fields = ['name', 'test1',]
