I got a type error showing that "is not serializable JSON". After adding session-related code, this error occurs.
views.py
def jlogin(request):
if request.method == 'POST':
username = request.POST['uname']
password = request.POST['pword']
user = authenticate(username=username, password=password)
if user is not None:
login(request,user)
print(user)
request.session['user']=user
return redirect('/feeds/')
else:
return render(request,'join/login.html')
else:
user = request.session.get('user')
print(user)
if user is None:
return render(request,'join/login.html')
else:
return render(request,'feeds/feeds.html')
login.html
<!DOCTYPE html>
<html>
<head>
<title>Login to dEEPsIGMA</title>

Username :
