【问题描述】：

我想修改表单域的属性。具体来说，登录表单：

(django-allauth 登录表单)

类LoginForm(forms.Form)：

password = PasswordField(label=_("Password"))
remember = forms.BooleanField(label=_("Remember Me"),
                              required=False)

user = None

def __init__(self, *args, **kwargs):
    super(LoginForm, self).__init__(*args, **kwargs)
    if app_settings.AUTHENTICATION_METHOD == AuthenticationMethod.EMAIL:
        login_widget = forms.TextInput(attrs='type': 'email',
                                              'placeholder':
                                              _('E-mail address'),
                                              'autofocus': 'autofocus')
        login_field = forms.EmailField(label=_("E-mail"),
                                       widget=login_widget)
    elif app_settings.AUTHENTICATION_METHOD \
            == AuthenticationMethod.USERNAME:
        login_widget = forms.TextInput(attrs='placeholder':
                                              _('Username'),
                                              'autofocus': 'autofocus')
        login_field = forms.CharField(label=_("Username"),
                                      widget=login_widget,
                                      max_length=30)
    else:
        assert app_settings.AUTHENTICATION_METHOD \
            == AuthenticationMethod.USERNAME_EMAIL
        login_widget = forms.TextInput(attrs='placeholder':
                                              _('Username or e-mail'),
                                              'autofocus': 'autofocus')
        login_field = forms.CharField(label=pgettext("field label",
                                                     "Login"),
                                      widget=login_widget)
    self.fields["login"] = login_field
    set_form_field_order(self,  ["login", "password", "remember"])

我如何覆盖（或覆盖）一个 django-allauth 表单域？救命！

【问题讨论】：

修改是什么意思？您要添加新字段还是修改现有字段，例如password 字段？

【参考方案1】：

您可以在settings.py 中使用ACCOUNT_FORMS 覆盖默认登录表单，例如：

ACCOUNT_FORMS = 'login': 'yourapp.forms.YourLoginForm'

并相应地写一个YourLoginForm。

# yourapp/forms.py

from allauth.account.forms import LoginForm

class YourLoginForm(LoginForm):
    def __init__(self, *args, **kwargs):
        super(YourLoginForm, self).__init__(*args, **kwargs)
        self.fields['login'].widget = forms.TextInput(attrs='type': 'email', 'class': 'yourclass')
        self.fields['password'].widget = forms.PasswordInput(attrs='class': 'yourclass')

【讨论】：

适用于登录表单、重置表单，但不适用于更改密码表单（即 ACCOUNT_FORMS='reset_password' : 'XYZ'

如何自定义表单中的验证规则？

【参考方案2】：

我知道您可以使用 ACCOUNT_SIGNUP_FORM_CLASS 设置变量覆盖注册表单类...但据我所知，无法更改登录表单。我在这里问了我自己的类似问题。

【参考方案3】：

class SignupForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
    super(SignupForm, self).__init__(*args, **kwargs)
    self.fields['first_name'].widget = forms.TextInput(attrs='placeholder': 'Enter first name')
    self.fields['last_name'].widget = forms.TextInput(attrs='placeholder': 'Enter last name')

#settings.py or base.py    
ACCOUNT_SIGNUP_FORM_CLASS = 'NameApp.forms.SignupForm'
