我有一个Django crispy表单:一个典型的注册表单,包含电子邮件地址,密码字段和提交操作.

我有一个隐藏字段从我的urls python文件传递到Django crispy表单,名为'billing_secret'.不同的URL的计费秘密是不同的.

目标:要有一个条款和条件单选复选框启用/禁用特定计费秘密的提交按钮,因此url.

我需要添加两件事.

1. 在Crispy表单中添加if语句,仅显示特定计费密钥的Radio复选框.例如,如果计费秘密是"apples",则显示无线电并默认为"no".如果计费秘密是其他任何东西使收音机隐藏,默认为是.

这是我到目前为止(不起作用).道歉我完全不熟悉Python.

email = forms.EmailField(label=_("Email"))
password1 = forms.CharField(widget=forms.PasswordInput,label=_("Password"))
billing_secret = forms.CharField()
termsandcond = forms.TypedChoiceField(
        label = "Do you agree to the T&C's?",
        choices = ((1, "Yes"), (0, "No")),
        coerce = lambda x: bool(int(x)),
        widget = forms.RadioSelect,
        initial = '0',
        required = True,
    )

def __init__(self, *args, **kwargs):
    billing_secret = kwargs.pop('billing_secret', None)
    super(RegistrationForm, self).__init__(*args, **kwargs)
    self.helper = FormHelper()
    self.helper.form_method = 'post'
    self.helper.form_action = '.'

    self.helper.layout = Layout(
        Field('email', placeholder=_("Email")),
        Field('password1', placeholder=_("Password")),
        Field('billing_secret', …

我在启动(清理构建并运行)我的JavaEE Web应用程序时有这个:
