我正在尝试为用户注册创建表单并添加一些自定义字段。为此,我将子类化了UserCretionForm并添加了字段,如django文档中所示。然后我基于这个表单创建了基于函数的视图和模板。现在,我可以成功创建用户,并按预期将此用户添加到管理面板。问题是,我无法为此表单的字段添加类和样式。除了用户名字段外,窗口小部件无法正常工作。我在这里添加我的脚本以更准确地说明我的问题:
forms.朋友
from django import forms
from django.contrib.auth.forms import UserCreationForm, AuthenticationForm
from django.contrib.auth.models import User
class SignUpForm(UserCreationForm):
first_name = forms.CharField(max_length=32, help_text='First name')
last_name = forms.CharField(max_length=32, help_text='Last name')
email = forms.EmailField(max_length=64, help_text='Enter a valid email address')
class Meta(UserCreationForm.Meta):
model = User
# I've tried both of these 'fields' declaration, result is the same
# fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2', )
fields = UserCreationForm.Meta.fields + ('first_name', 'last_name', 'email',)
widgets = {
'username': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Username'}),
'first_name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'First Name'}),
'last_name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Last Name'}),
'email': forms.EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email'}),
'password1': forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password'}),
'password2': forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password Again'}),
}
views.朋友
from django.contrib.auth import login, authenticate
from django.contrib.auth.views import LoginView
from django.shortcuts import render, redirect
from .forms import SignUpForm, SignInForm
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
form.save()
username = form.cleaned_data.get('username')
raw_password = form.cleaned_data.get('password1')
user = authenticate(username=username, password=raw_password)
login(request, user)
return redirect('/')
else:
form = SignUpForm()
return render
'forms.py'中的小部件无效,除了'username'字段。换句话说,在Web浏览器中,“username”输入显示为“class ='form-control'”和“placeholder ='Username'”,但其他字段没有我期望的class和placeholder属性。可能是什么原因?
您不需要在窗口小部件下定义字段。在类级别将它们定义为静态。
class SignUpForm(UserCreationForm):
username = forms.CharField(forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Username'}))
first_name = forms.CharField(forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'First Name'}), max_length=32, help_text='First name')
last_name=forms.CharField(forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Last Name'}), max_length=32, help_text='Last name')
email=forms.EmailField(forms.EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email'}), max_length=64, help_text='Enter a valid email address')
password1=forms.CharField(forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password'}))
password2=forms.CharField(forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password Again'}))
class Meta(UserCreationForm.Meta):
model = User
# I've tried both of these 'fields' declaration, result is the same
# fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2', )
fields = UserCreationForm.Meta.fields + ('first_name', 'last_name', 'email',)
