In Django how to display username upon successful login

Question

I am using the django User model to store user's information. Now after login I want to redirect the user to the dashboard where a message should be delayed: Welcome <his_first_name>. I tried the following code:

@login_required(login_url='login')
def dashboard(request):
    return render(request, 'accounts/dashboard.html', {"name": user.first_name})

but I am getting the following error: name 'user' is not defined. What am I missing?

my register function looks something like this:

from django.contrib.auth.models import User

def register(request):
    if request.method == 'POST':

        firstname = request.POST['firstname']
        lastname = request.POST['lastname']
        username = request.POST['username']
        password = request.POST['password']

        user = User.objects.create_user(first_name=firstname, last_name=lastname, username=username, password=password)
        user.save()
        return redirect('login')

In the above code, what I understand is that user is an object of the User class, then how can all objects have the same name user, what am I misunderstanding?

Edit: thanks to the answers below, I missed the request keyword before user.first_name, it should have been:

return render(request, 'accounts/dashboard.html', {"name": request.user.first_name})

Get user from request

request.user

and use in your function.

@login_required(login_url='login')
def dashboard(request):
    return render(request, 'accounts/dashboard.html', {"name": request.user.first_name})

Safe way to get user's first name:

request.user.get_short_name()

Also you can get full name using:

request.user.get_full_name()
