Django UserCreationForm custom fields


I am trying to create form for user registration and add some custom fields. For doing that, I’ve subclassed UserCretionForm and added fields as shown in django documentation. Then I’ve created function-based view and template based on this form. Now, I can successfully create user and this user is added to admin panel as expected. Problem is that, I can’t add class and style for this form’s fields. Widgets are not working except for username field. I’m adding my scripts here for illustrating my problem more accurately:

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'}),

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():
            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('/')
        form = SignUpForm()
    return render

Widgets in ‘’ are not working except for ‘username’ field. In other words, in web browser ‘username’ input is shown with “class=’form-control'” and “placeholder=’Username'”, but other fields don’t have class and placeholder attribute as I expected. What can be the reason?

You don’t need to define fields unders widgets. Define them as static at class level.

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',)

Just need to add a note on @Chirdeep answer, if you tried to render the form you would lose the field.help_text for the password.

In order to fix, we can re-write the forms as below
please note to import the password_validation from django.contrib.auth

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import password_validation
from django.contrib.auth.models import User
from django.utils.translation import gettext_lazy as _
from django.contrib.auth.validators import UnicodeUsernameValidator

username_validator = UnicodeUsernameValidator()

class SignUpForm(UserCreationForm):
    first_name = forms.CharField(max_length=12, min_length=4, required=True, help_text='Required: First Name',
                                widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'First Name'}))
    last_name = forms.CharField(max_length=12, min_length=4, required=True, help_text='Required: Last Name',
                               widget=(forms.TextInput(attrs={'class': 'form-control'})))
    email = forms.EmailField(max_length=50, help_text='Required. Inform a valid email address.',
                             widget=(forms.TextInput(attrs={'class': 'form-control'})))
    password1 = forms.CharField(label=_('Password'),
                                widget=(forms.PasswordInput(attrs={'class': 'form-control'})),
    password2 = forms.CharField(label=_('Password Confirmation'), widget=forms.PasswordInput(attrs={'class': 'form-control'}),
                                help_text=_('Just Enter the same password, for confirmation'))
    username = forms.CharField(
        help_text=_('Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only.'),
        error_messages={'unique': _("A user with that username already exists.")},
        widget=forms.TextInput(attrs={'class': 'form-control'})

    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2',)
