python之Django 模型形式 : Exclude a field which is not in Model

我很难调试它。我想在扩展的 modelform UpdateRegModelForm 中排除 RegModelForm 的 confirm_password。我试图在 UpdateRegModelForm 的 Meta 类中使用 exclude 但它似乎在呈现 UpdateRegModelForm 时显示 confirm_password .不确定如何前进。

class RegModelForm(forms.ModelForm): 
 
    org_admin_email = forms.CharField( 
        label='If you know who should be the Admin, please add their email address below.' 
              ' We\'ll send them an email inviting them to join the platform as the organization admin.', 
        required=False, 
        widget=forms.EmailInput(attrs=({'placeholder': 'Email'})) 
    ) 
    organization_name = forms.CharField( 
        max_length=255, 
        label='Organization Name', 
        widget=forms.TextInput( 
            attrs={'placeholder': 'Organization Name'} 
        ) 
    ) 
 
    confirm_password = forms.CharField( 
        label='Confirm Password', widget=forms.PasswordInput(attrs={'placeholder': 'Confirm Password'}) 
    ) 
 
    class Meta: 
        model = ExtendedProfile 
 
        fields = ( 
            'confirm_password', 'first_name', 'last_name', 
            'organization_name', 'is_currently_employed', 'is_poc', 'org_admin_email', 
        ) 
 
        labels = { 
            'is_currently_employed': "Check here if you're currently not employed.", 
            'is_poc': 'Are you the Admin of your organization?' 
        } 
 
        widgets = { 
            'first_name': forms.TextInput(attrs={'placeholder': 'First Name'}), 
            'last_name': forms.TextInput(attrs={'placeholder': 'Last Name'}), 
            'is_poc': forms.RadioSelect() 
        } 
 
 
class UpdateRegModelForm(RegModelForm): 
    class Meta(RegModelForm.Meta): 
        exclude = ('confirm_password',) 

请您参考如下方法:

fields 和 exclude 属性仅与从模型创建的字段相关。由于您已直接在表单本身中指定了 confirm_password，因此它将始终存在。

删除的方法是从表单的fields字典中删除。您可以在 __init__ 方法中执行此操作:

class UpdateRegModelForm(RegModelForm): 
    def __init__(self, *args, **kwargs): 
        super(UpdateRegModelForm, self).__init__(*args, **kwargs) 
        self.fields.pop('confirm_password') 

你根本不需要在这个子类中定义 Meta。
