I built a simple signup form which will take data as user will click submit it will save it in database. But for some reason I am able to validate it. I removed all the validations and added again too. Not sure where I am missing?

Forms.py:

class RegisterForm(UserCreationForm):
    email = forms.EmailField(max_length=100,help_text='Enter Email Address', required=True,widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Email'}))
    
    first_name = forms.CharField(max_length=100,help_text='Enter First Name', required=True,widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'First Name'}))
    
    last_name = forms.CharField(max_length=100,help_text='Enter Last Name', required=True,widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Last Name'}))
    
    username = forms.CharField(max_length=100,help_text='Enter Username', required=True,widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Username'}))
    
    password = forms.CharField(max_length=200,help_text='Enter Password', required=True,widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password'}))
    
    password2 = forms.CharField(max_length=200,help_text='Enter your Password again', required=True,widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password'}))  
    
    #check = forms.BooleanField(required = True)
    
    class Meta:
        model = User
        fields = [
            'username', 'email', 'first_name', 'last_name', 'password', 'password2' #, 'check'
        ]

Views.py:

def register(request):
    if request.method == 'GET': #when you request a form it is in a get request 
        form = RegisterForm()
        context = {'form' : form} #this creates a object which you want to send to the front end
        return render(request, 'signup-login.html', context) # here we pushing that form to the html page 
    
    if request.method == 'POST': #when you submit a form it is POST request
        form = RegisterForm(request.POST)
        if form.is_valid():
             form.save()
             user = form.cleaned_data.get('username')
             messages.success(request, 'Account was created for' + user)
             return redirect('home_page')
        else:
            messages.error(request, 'Error Processing Your Request')
            context = {'form' : form}
            return render(request, 'signup-login.html', context)

    return render(request, 'signup-login.html', {})

form html:

                </div>
              </div>     

            </form>

The code is displaying so I am assuming there is no error in the html side of it

What I have tried:

I tried several different values again and again but it is not validating.
