Django密码字段输入显示为明文forms.PasswordInput宣言

Question

Django密码字段输入显示为明文，尽管widget=forms.PasswordInput声明：

在表单.py在

from django.contrib.auth.models import User
class LoginForm(forms.ModelForm):
    # specify password type so that passwords show up as *******, not plaintext
    # but this doesn't work if placeholder = ''
    password = forms.CharField(widget=forms.PasswordInput)

    class Meta:
        model = User
        fields = ["username", "password"]

    def __init__(self, *args, **kwargs):
        # first call the 'real' __init__()
        super(LoginForm, self).__init__(*args, **kwargs)
        # then do extra stuff:
        self.fields['username'].help_text = ''
        self.fields['password'].widget = forms.TextInput(attrs={'placeholder': ''})
        self.fields['password'].widget.attrs['class'] = 'form-control'

所以有趣的是，当我在模板中显示这个表单时，password值显示为纯文本而不是'*****'文本。但前提是我加上'placeholder': ''行。我检查了form元素，发现当我添加'placeholder': ''行时，type='password'在呈现的HTML的<input type='FOO'></input>元素中被改为type='text'。在

您不应将forms.TextInput用作密码字段。Django provides a PasswordInput widget那更合适。试试这个：

class Meta:
    model = User
    fields = ["username", "password"]

def __init__(self, *args, **kwargs):
    # first call the 'real' __init__()
    super(LoginForm, self).__init__(*args, **kwargs)
    # then do extra stuff:
    self.fields['username'].help_text = ''
    self.fields['password'].widget = forms.PasswordInput(attrs={'placeholder': ''})
    self.fields['password'].widget.attrs['class'] = 'form-control'

虽然您可以手动编辑字段的类型，但最好使用小部件。在
