【问题描述】：

我尝试在我的注册表单中使用 4 个字段启用占位符：电话、电子邮件、密码 1、密码 2。前两个字段都正确，但密码字段不起作用。

forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from customuser.models import User
from django.forms import TextInput,EmailInput,PasswordInput

class SignUpForm(UserCreationForm):    


    class Meta:
        model = User
        fields = ('phone', 'email', 'password1', 'password2', 'is_client','is_partner')
        widgets = {
            'email': EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email adress'}),
            'phone': TextInput(attrs={'class': 'form-control', 'placeholder': 'Phone number  +79011234567'}),
            'password1': PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password from numbers and letters of the Latin alphabet'}),
            'password2': PasswordInput(attrs={'class': 'form-control', 'placeholder': '
Password confirmation'}),

        }

我测试了@Alasdair 的解决方案并以这种方式为我工作：

from django import forms
from django.contrib import auth
from django.contrib.auth.forms import UserCreationForm
from django.utils.translation import ugettext_lazy as _


class RegistrationForm(UserCreationForm):
    first_name = forms.CharField(label=_("First name"), widget=forms.TextInput(attrs={'placeholder': _("First name")}))
    email = forms.EmailField(label=_("Email"), widget=forms.TextInput(attrs={'placeholder': _("Email")}))

    class Meta(UserCreationForm.Meta):
        model = auth.get_user_model()
        fields = [
            'first_name',
            'email',
            'password1',
            'password2'
        ]

    def __init__(self, *args, **kwargs):
        super(InviteRegistrationForm, self).__init__(*args, **kwargs)
        self.fields['password1'].widget = forms.PasswordInput(attrs={'placeholder': _("Password")})
        self.fields['password2'].widget = forms.PasswordInput(attrs={'placeholder': _("Password")})

【解决方案2】：

Meta.widgets 选项不适用于在表单中声明的字段。请参阅note in the docs。在这种情况下，password1 和 password2 在 UserCreationForm 上声明（它们不是模型字段），因此您不能在 widgets 中使用它们。

您可以改为在 __init__ 方法中设置小部件：

class SignUpForm(UserCreationForm):    
    class Meta:
        model = User
        fields = ('phone', 'email', 'is_client', 'is_partner')
        widgets = {
            'email': EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email adress'}),
            'phone': TextInput(attrs={'class': 'form-control', 'placeholder': 'Phone number  +79011234567'}),
    }

    def __init__(self, *args, **kwargs):
        super(SignUpForm, self).__init__(*args, **kwargs)
        self.fields['password1'].widget = PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password from numbers and letters of the Latin alphabet'})
        self.fields['password2'].widget = PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password confirmation'})

嗯，我认为这是我需要的，但由于某种原因它对我不起作用（
我没有测试过代码，但我无法发现它的问题。希望你能弄明白。

【解决方案3】：

这段代码运行良好

class SignUpForm(UserCreationForm):    
    password1 = forms.CharField(max_length=16, widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password from numbers and letters of the Latin alphabet'}))
    password2 = forms.CharField(max_length=16, widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password confirm'}))
    class Meta:
        model = User
        fields = ('phone', 'email', 'password1', 'password2', 'is_client','is_partner')
        widgets = {
            'email': EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email adress'}),
            'phone': TextInput(attrs={'class': 'form-control', 'placeholder': 'Phone number format +79011234567'}),


        }
