我有一个基类,即Django。 然后,子女阶级继承父母的遗产,包括所有领域,但我需要改变父母的外地选择之一,例如<代码>label<>/code>,required等。
例:
class BaseForm(forms.Form):
userid = forms.CharField(required=True)
class ChildForm(BaseForm):
# I need to change the parent field option
userid = forms.CharField(required=False)
Any suggestions?
你们应该做些什么。
它特别适合这一情形,因为它符合压倒一切的<代码>ModelForm领域的确切模式。
如果你需要保留财产,你不了解或不了解你控制(或你知道什么),你可以否决<代码>_init_方法,并通过<代码>自行进入表格领域。
class ChildForm(BaseForm):
def __init__(self, *args, **kwargs):
super(ChildForm, self).__init__(*args, **kwargs)
self.fields[ userid ].required = False
