I am tryin to add an remember me option to my login page. Whenever i try logining and i click on the remember me option, everything works fine. When i do not click on it, it raises this error.

Here is my forms.py

class Signin(forms.Form):
    username = forms.CharField(
        max_length=9,
        widget=forms.TextInput(
            attrs={
                "id": "input_64",
                "name": "q64_typeA",
                "data-type": "input-textbox",
                "class": "form-textbox validate[required]",
                "data-defaultvalue": "",
                "size": "20",
                "placeholder": "180591001",
                "data-component": "textbox",
                "aria-labelledby": "label_64",
                "required": "",
            }
        ),
    )
    password = forms.CharField(
        max_length=255,
        widget=forms.PasswordInput(
            attrs={
                "id": "first_66",
                "name": "q66_name66[first]",
                "class": "form-textbox validate[required]",
                "data-defaultvalue": "",
                "autoComplete": "section-input_66 given-name",
                "size": "10",
                "data-component": "first",
                "aria-labelledby": "label_66 sublabel_66_first",
                "required": "",
                "placeholder": "\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022\u2022",
            }
        ),
    )
    remember = forms.BooleanField(required=False, initial=False)

views.py

def signin(request):
    if request.user.is_authenticated:
        return redirect(index)
    if request.method == "POST":
        form = Signin(request.POST)
        if form.is_valid():
            username = request.POST["username"]
            password = request.POST["password"]
            remember = request.POST["remember"]

            user = User.objects.filter(username=username).exists()
            if user:
                get_user = User.objects.filter(username=username)
                check_pass = check_password(password, get_user[0].password)
                if not check_pass:
                    messages.error(request, "incorrect password")
                    return redirect(signin)
                else:
                    login(request, get_user[0])
                    if not remember:
                        request.session.set_expiry(0)
                    return redirect(index)
            else:
                messages.error(request, "Invalid User")
                return redirect(signin)
    else:
        form = Signin()
        return render(request, "accounts/login.html", {"form": form})

here is the error it returns when i do not click on the remember me option.

        </div>
      </li>
    </ul>

What i want to achieve is to make the remember me option not required.

CodePudding user response：

Try with get() method

remember = request.POST.get("remember")
