Leave a Comment / Django, Python / By Ravi

Assuming you are created models & Login , Register html Template

Go to URLS.PY

path('login/', views.login, name='login'),
path('register/', views.register, name='register'),
path('index/', views.index, name='index'),
path('logout/', views.logout, name='logout'),

Go to VIEWS.PY

def register(request):
    if request.method=='POST':
        username=request.POST.get('username')
        email = request.POST.get('email')
        password = request.POST.get('password')

        user_list= models.administrator.objects.filter(username= username)

        error_name=[]
        if user_list:
            error_name='The user name already exists'

            return render (request, 'register.html',{'error_name': error_name})
        else:
            username=models.administrator.objects.create(username=username, password=password,email=email)
            username.save()

        return redirect('/login')
    return render(request, 'register.html')

def login(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')

        obj_user = models.administrator.objects.filter(username=username, password=password)
        if obj_user:
            request.session["uid"]=request.POST.get('username')
            messages.success(request, "Login Successfully.")
            return redirect('/index')
        error = 'Wrong username and password'

    return render(request, "login.html", locals())  #--locals() passed to render() is to send all local variables of the view

def index(request):
    if request.session.has_key('uid'):
        return render(request, "index.html")
    else:
        return redirect('/login')


def logout(request):
    try:
        del request.session["uid"]
    except KeyError:
        pass
    return redirect("/login")
