Unable to login and redirect in django - django

Question

I am unable to login and redirect to home page using the custom login view (user_login) and AuthenticationForm. However, if i login using the admin page (http://127.0.0.1:8000/admin) and then reopen login page it automaticaly redirects to home page.
There is some issue related to authentication which is not getting done from my custom login page/view .I am unable to fix this or identify resolution based on answers provided online.
There is another issue regarding the URL it is showing as
http://127.0.0.1:8000/login/?csrfmiddlewaretoken=FhHQjhGGgFDwcikpH9kl3OwQMcZisjWS2zvMHFGBU6KxGNWbamgago7FhtSs8MeN&username=admin&password=admin
However, Password and Username should not be showing in the URL if form method is post.
URL
urlpatterns = [
path("", views.index, name="index"),
path("signup/", views.user_signup, name="signup"),
path("login/", views.user_login, name="login"),
path("home/", views.homepage, name="home"),]
Views
def user_login(request):
if request.user.is_authenticated:
return redirect("/home")
else:
if request.method == "POST":
form = AuthenticationForm(request, data=request.POST)
if form.is_valid():
username = form.cleaned_data.get("username")
password = form.cleaned_data.get("password")
user = authenticate(username=username, password=password)
if user is not None:
login(request, user)
return redirect("home")
else:
messages.error(request, "Invalid username or password.")
else:
messages.error(request, "Invalid username or password.")
form = AuthenticationForm()
return render(
request=request,
template_name="socialapp/login.html",
context={"login_form": form},
)
def homepage(request):
return render(request=request, template_name="socialapp/home.html")
Login HTML
<form action="{% url 'login' %}" id="login-form" method="post" class="bg-white shadow-md rounded px-8 pt-6 pb-8 mb-4">
{% csrf_token %}
{{ login_form|crispy }}
<button type="submit" class="text-white bg-blue-700 hover:bg-blue-800 focus:ring-4 focus:ring-blue-300 font-medium rounded-lg text-sm px-5 py-2.5 mr-2 mb-2 dark:bg-blue-600 dark:hover:bg-blue-700 focus:outline-none dark:focus:ring-blue-800" value="Submit">Login</button>
</form>
Home HTML
{% block main %}
<div class="flex flex-col min-h-screen justify-center items-center ">
<h1>Welcome to Home</h1>
</div>
{% endblock main %}
Settings
LOGIN_URL = "/login"
LOGIN_REDIRECT_URL = "/home"

You need to check login in else part
def SigninView(request):
if request.method == 'POST':
form = AuthenticationForm(request, data=request.POST)
username = request.POST.get("username")
password = request.POST.get("password")
user = authenticate(username=username,password=password)
if user is None:
messages.error(request,'Please Enter Correct Credinatial')
return redirect('/signin/')
else:
login(request,user)
messages.info(request,'Login Successful')
return redirect('/dashboard/')
else:
if request.user.is_authenticated:
return redirect('/dashboard/')
else:
form = AuthenticationForm()
return render(request,'signin.html',{'form':form})
