Please Help. How Can I Make My Signup Form to Work and Send new users to the database?

I am trying to build a Recruitment Agency Website following and making adjustments to a tutorial from Code with Stein. I have built the signup.html template, I have coded base.html, models.py, the views.py and the urls.py. However when I try to signup a new user, there is no response. In other words the new user does not reflect in Users in the admin panel. Please help. What am I missing?
Here is my forms.py file

from django import forms  # type:ignore
from django.contrib.auth.forms import UserCreationForm  # type:ignore
from django.contrib.auth.models import User  # type:ignore


class SignupForm(UserCreationForm):
    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")

    username = forms.CharField(
        widget=forms.TextInput(
            attrs={
                "placeholder": "Enter Your username",
                "class": "w-full py-4 px-6 rounded-xl",
            }
        )
    )
    email = forms.CharField(
        widget=forms.EmailInput(
            attrs={
                "placeholder": "Enter Your Email",
                "class": "w-full py-4 px-6 rounded-xl",
            }
        )
    )
    password1 = forms.CharField(
        widget=forms.PasswordInput(
            attrs={
                "placeholder": "Enter Your password",
                "class": "w-full py-4 px-6 rounded-xl",
            }
        )
    )
    password2 = forms.CharField(
        widget=forms.PasswordInput(
            attrs={
                "placeholder": "Enter Your password again",
                "class": "w-full py-4 px-6 rounded-xl",
            }
        )
    )

the views.py file

from django.shortcuts import render, redirect  # type:ignore
from item.models import Category, Item

from .forms import SignupForm


def index(request):
    items = Item.objects.filter(is_sold=False)[0:9]
    categories = Category.objects.all()
    return render(
        request, "core/index.html", {"categories": categories, "items": items}
    )


def contact(request):
    return render(request, "core/contact.html")


def about(request):
    return render(request, "core/about.html")


def signup(request):
    if request.method == "POST":
        form = SignupForm(request.POST)

        if form.is_valid():
            form.save()

            return redirect("/login/")
    else:
        form = SignupForm()

    return render(request, "core/signup.html", {"form": form})

the signup.html file
