[Python] Django KeyError at forms.py

I'm learning django and I'm playing around with forms and registering users. When I submit the registration form with the username, email, password, and confirm password fields filled, I get an error that states:

KeyError at director/register/ "confirm_password"

However, when I look at the POST data in the error message I clearly see the data I'm trying to access.



csrfmiddlewaretoken: blahblahblabh

username: dasdasd

email: dasd@dsada.com

password: test123!

confirm_password: test123!

Below are the forms.py, portion of the views.py, register.html files.

forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm

from .models import CustomUser

class CustomUserCreationForm(UserCreationForm):

class Meta:
model = CustomUser
fields = ("email", "password")

class CustomUserChangeForm(UserChangeForm):

class Meta:
model = CustomUser
fields = ("email", "password")

class RegisterUser(forms.Form):
username = forms.CharField(max_length=64, required=True)
email = forms.EmailField()
password = forms.CharField(max_length=128, widget=forms.PasswordInput(), required=True)
confirm_password = forms.CharField(max_length=128, widget=forms.PasswordInput(), required=True)

def clean_username(self):
username = self.cleaned_data["username"]
if CustomUser.objects.filter(username=username).exists():
raise forms.ValidationError("Email already exists")
return username

def clean_email(self):
email = self.cleaned_data['email']
if CustomUser.objects.filter(email=email).exists():
raise forms.ValidationError("Email already exists")
return email

def clean_password(self):
password = self.cleaned_data['password']
confirm_password = self.cleaned_data['confirm_password']
if password != confirm_password:
raise forms.ValidationError("Passwords do not match")
return password```


views.py (register_view)

def register_view (request):
if request.method == "POST":
form = RegisterUser(request.POST)
if form.is_valid():
new_user = form.save()
login(request, new_user)
return redirect('home')
else:
form = RegisterUser()
return render(request, 'pokedex/register.html', {'form': form})


register.html

{% extends 'pokedex/layout.html' %}

{% block title %}Register{% endblock title %}


{% block body %}

<h1>Register</h1>

{% if form.errors %}
<div class="alert alert-danger">
<ul>
{% for error in form.errors.values %}
<li>{{ error }}</li>
{% endfor %}
</ul>
</div>
{% endif %}

<form action="{% url 'register' %}" method="post">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Register">
</form>

{% endblock body %}
