python - 如何在html页面上添加注释

Question

我使用命令提示符运行我的 python 服务器，其中显示下面的打印语句(如果到达)。如何在模板 login.html

上显示它们

View .py

def home(request):
    templatename="login.html"
    if request.method=="POST":
        u=request.POST.get("username")
        p=request.POST.get("password")
        user=authenticate(username=u, password=p)
        if user is not None:
            if user.is_active:
                print "This User is valid, active and authenticated"
                login(request,user)
                return HttpResponseRedirect("/welcome/")
            else:
                print("This User is valid but the account has been disabled")
        else:
            print("The Username and Password entered were incorrect")
    else:
        user=None
    return render_to_response(templatename,{'user': user},RequestContext(request))

将要在模板 login.html 上显示的语句存储在变量(此处为“状态”)中，如下所示:

def home(request):
    templatename="login.html"
    if request.method=="POST":
        u=request.POST.get("username")
        p=request.POST.get("password")
        user=authenticate(username=u, password=p)
        if user is not None:
            if user.is_active:
                state="This User is valid, active and authenticated"
                login(request,user)
                return HttpResponseRedirect("/welcome/")
            else:
                state="This User is valid but the account has been disabled"
        else:
            state="The Username and Password entered were incorrect"
    else:
        user=None
    return render_to_response(templatename,{'user': user,'state':state},RequestContext(request))

将字典中的状态传递给render_to_response()。
访问 login.html 页面中的状态为 {{state}}。
你的工作已经完成。
