Redirect to the main page if authenticated - django

Question

I got some problems with redirecting.
When I already logged in, and try go to "/accounts/login", it still goes to this link, and if I change in url.py path for example "accounts/logins", the redirect is working, but if not authenticated it says me that:
UnboundLocalError: local variable 'context' referenced before assignment
AND "/accounts/login" is still available if I remove it in url.py
views.py
def loginPage(request):
if request.user.is_authenticated:
return redirect("index")
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('index')
else:
messages.info(request, 'Username OR password is incorrect')
context = {}
return render(request, 'registration/login.html', context)
url.py
urlpatterns = [
path('login/', views.loginPage, name='loginPage'),
path('logout/', views.logoutUser, name='logoutUser'),
path('register/', views.registerPage, name='registerPage'),
]

Answer 1

In order to redirect to an specific url once logged in you can set in your settings.py the following:
LOGIN_REDIRECT_URL = '/'
hope this is what are you looking for

Answer 2

Try this code...
def loginPage(request):
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('index')
else:
messages.info(request, 'Username OR password is incorrect')
return redirect('/login/')
else:
if request.user.is_authenticated:
return redirect('/index/')
else:
context = {}
return render(request, 'registration/login.html',context)
