Is it possible to create login systems using based on sessions. Actually this is my first django project. Please Guide me. Thank you.

推荐答案

在登录时，检查用户名和密码后，创建一个会话，在其中设置其用户对象或对象ID.在这种情况下，我保留了用户ID.

While login, after checking username and password create a session in which set their user object or it's object id in it. In this case i kept user id.

def login(request):
    if request.method == "GET":
        if (Users.objects.filter(username = request.GET.get("uname"), password = request.GET.get("upswd"))).exists():
            user = Users.objects.get(username = request.GET.get("uname"), password = request.GET.get("upswd"))
            request.session["user"] = user.id
            # request.session.set_expiry(10)
            # it shows home page
            return render(request,"home.html")
    #it shows again login page
    return render(request,"Login.html")

仅在登录页面上设置会话，其余的将检查页面是否包含该会话.例如，在登录首页后，您应检查请求是否包含用户会话.

only in login page you will set session, In remaining you will check whether page contains that session or not.For example, in after login in home page you should check whether request contains user session or not.

if request.session.has_key("user"):
    userid = request.session["user"]
    #displaying all items in database
    context={"items":Products.objects.all()}
    return render(request,"home.html",context)
