Why the User data are not updated? in Django?

I have a Model called UserAccount, I have tried several ways to update the data for an existing user, it responds that changes are successful without any error but still nothing is reflecting in Database

Here is the Model

class UserAccount(AbstractBaseUser,PermissionsMixin):
    first_name = models.CharField( max_length=100)
    last_name = models.CharField(max_length=100)
    email = models.EmailField(_("email"),validators=[EmailValidator()],unique=True)
    date_added = models.DateTimeField(auto_now_add=True)
    phone = models.CharField(max_length=20, validators=[RegexValidator(r'^\d{12}$', 'Enter a valid phone number.')])
    profile_picture = models.ImageField(upload_to='media/users_photos/%Y/%m',null=True,blank=True)
    employee_id = models.IntegerField(validators=[MinValueValidator(1), MaxValueValidator(999)], null=True,blank=True)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    last_login = models.DateTimeField(auto_now_add=True , null=True)

    objects = CustomUserAccountManager()

    USERNAME_FIELD = "email"
    REQUIRED_FIELDS = ["first_name", "last_name","phone"]
    EMAIL_FIELD = "email"

    class Role(models.TextChoices):
        ADMIN = "Admin", "Admin"
        MANAGER = "Manager", "manager"
        NORMALUSER = "Normal", "normaluser"

    base_role = Role.NORMALUSER

    role = models.CharField(max_length=50, choices=Role.choices)

    def save(self, *args, **kwargs):
        if not self.pk:
            self.role = self.base_role
            return super().save(*args, **kwargs)

    def __str__(self):
        if self.first_name and self.last_name:
            fullname = f'{self.first_name} {self.last_name}'
        elif self.first_name:
            fullname = self.first_name
        elif self.last_name:
            fullname = self.last_name
        else:
            fullname = "Unnamed User"
        return fullname


    # Add related_name to avoid clashes
    groups = models.ManyToManyField(
        'auth.Group',
        related_name='user_accounts',
        blank=True,
        help_text='The groups this user belongs to. A user will get all permissions granted to each of their groups.',
        verbose_name='groups',
    )
    user_permissions = models.ManyToManyField(
        'auth.Permission',
        related_name='user_accounts',
        blank=True,
        help_text='Specific permissions for this user.',
        verbose_name='user permissions',
    )

    def get_username(self):
        return self.email

Here is theForm

class EditUserForm(forms.ModelForm):


    class Meta:
        model = UserAccount
        fields = ['first_name', 'last_name', 'email', 'phone', 'profile_picture', 'employee_id']

Here is the View

def edit_ni_user(request , user_id):

    request_user = get_object_or_404(UserAccount,id=user_id)
    edit_user_form = EditUserForm()


    if request.method == "POST":
        edit_user_form =EditUserForm(request.POST, request.FILES , instance=request_user)
        if edit_user_form.is_valid():
            print("edit_user_form is valid")

            newfirst_name = edit_user_form.cleaned_data['first_name']
            newlast_name = edit_user_form.cleaned_data['last_name']
            newphone = edit_user_form.cleaned_data['phone']
            newprofile_picture = edit_user_form.cleaned_data['profile_picture']
            newemployeeid = edit_user_form.cleaned_data['employee_id']

            request_user.first_name = newfirst_name
            request_user.last_name = newlast_name
            request_user.phone = newphone
            request_user.profile_picture = newprofile_picture
            request_user.employee_id= newemployeeid
            request_user.email = request_user.email
            request_user.save()
  
            print(get_object_or_404(UserAccount,id=user_id))

            print(UserAccount.objects.filter(id = request_user.pk).first())
            messages.success(request, f" {request_user}  Edited Successfully")

            return redirect('index')
        else:
            # Iterate over form errors and add appropriate messages
            for field, errors in edit_user_form.errors.items():
                for error in errors:
                     messages.error(request, f'{field}: {error}')
    elif request.method=="GET":

        edit_user_form = EditUserForm(instance = request_user)
