无法在 __init__ 处将字段添加到 ModelForm
我的 ModelForm 遇到问题。显示字段 test1，但不显示 test2-。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。

Thank you.

我无法在 Django 1.4 中使用 self.Meta.fields.append ，因为所讨论的 fields 是一个元组。例如，您必须使用 self.Meta.fields += ('another_field',) 连接。
I couldn't use self.Meta.fields.append in Django 1.4, because the fields in question is a tuple. You have to concatenate with self.Meta.fields += ('another_field',) instead, for example.
