Не отбражаются поля формы django django-widget-tweaks

У меня не отображаются поля формы. Я только пытаюсь разобраться. Понимаю, что у меня просто неопределена форма. Подскажите что не так я увязал?

views.py

from django.shortcuts import render, redirect
from django.contrib import messages
from users.forms import UserRegisterForm


def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(request, f'Ваш аккаунт создан: можно войти на сайт.')
            return redirect('home')
    else:
        form = UserRegisterForm()
    return render(request, 'templates/register.html', {'form': form})

forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from users.models import Profile


class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()
    

    class Meta:
        model = Profile
        fields = ['first_name', 'last_name', 'email', 'password1', 'password2']
        widgets = {
            'first_name' : forms.CharField (attrs={'class': 'form-group'}),
            'last_name' : forms.CharField (attrs={'class': 'form-group'}),
            'email': forms.EmailInput(attrs={'class': 'form-group'}),
            'usermane': forms.EmailInput(attrs={'class': 'form-group'}),
            'password1': forms.PasswordInput(attrs={'class': 'form-group'}),
            'password2': forms.PasswordInput(attrs={'class': 'form-group'}),
        }

    def clean_password2(self):
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError(
                self.error_messages['password_mismatch'],
                code='password_mismatch',
            )
        return password2

models.py

from django.db import models
from django.contrib.auth.models import User


class Profile(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    email = models.EmailField(max_length=254)
    username = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

    def __str__(self):
        return f'{self.user.username} Profile'
