Django login problem, how to implement in my case?

Question

Django

I have an account model with user data. When I check in views.py if there is a login and password in the database similar to the one entered by the user on the site, if there is such data, I create contextlogin = request.POST['login'], and pass this variable to html and through jinja I check for data the name of this person. But the problem is that each user logs in and the contextlogin is overwritten and other users change their data after the page is reloaded, how can this be fixed?

Views.py :

def main(request):
    global contextlogin
    global context
    if request.method == "POST":
        for i in account.objects.all():
            if i.account_login == request.POST['login']:
                if i.account_password == request.POST['password']:
                    context = account.objects.all()
                    contextlogin = request.POST['login']
    return render(request, "fr/main.html")

def profile(request):
    global context
    global contextlogin
    return render(request, "fr/profile.html", {'context': context, 'contextlogin': contextlogin})

main.html:

<form action = "" method = 'POST'>
    {% csrf_token %}
    <div id = 'login'>
        <p title = 'Вход в аккаунт' style = 'text-align: center; margin-left: -30px;'>Вход в аккаунт</p>

    </form>

I hope you got what I meant()

global in Django? Seriously?
The entire required context must either be calculated each time, or it is already in request, the same request.user, but for this you need to use the standard authentication system.
