基于url参数在django中创建自定义装饰器

Question

我有两个登录网址：

1. /简档/登录/
2. /暴民/简档/登录/

我有一个观点，

@login_required
def favorited_spreads(request ,page_template='spreads/favorited_spreads_ajax.html',
        template='spreads/favorited_spreads.html',mode=None):
    profile = request.user.profiles
    spreads = profile.favorite_by.all()
    context = {
            'spreads': spreads,
            'profile': profile,
        }
    if request.is_ajax():
        template=page_template
    return render(request, template,context)

我的两个网址是：

 url(r'^favorites/$',
    'favorited_spreads', name='favorited_spreads'),
url(r'^mob/favorites/$',
        'favorited_spreads',{
               'template':'mobapps/spreads/favorited_spreads.html',"mode":"mob"}, name='favorited_spreads_mob'),

现在我的问题是，我想要一个装饰者而不是@login_required说@custom_login_required，如果用户未经过身份验证并转到网址/favorites/ here mode=None，则应将其重定向到网址/profile/login/。

如果他要通过身份验证来定位/mob/favorites/（此处为mode ='mob'），则应将其重定向到登录网址/mob/profile/login/。

非常感谢任何帮助。如果问题不明确请评论。

我自己创建了一个自定义装饰器，

def custom_login_required(function,redirect_field_name=REDIRECT_FIELD_NAME):
    def wrapped_func(request,mode=None, *args,**kwargs):
        login_url=settings.MOBILE_LOGIN_URL if mode else settings.LOGIN_URL
        if request.user.is_authenticated():
            return function(request, mode=mode,*args, **kwargs)
        path = request.build_absolute_uri()
        # If the login url is the same scheme and net location then just
        # use the path as the "next" url.
        login_scheme, login_netloc = urlparse.urlparse(login_url or
                                                    settings.LOGIN_URL)[:2]
        current_scheme, current_netloc = urlparse.urlparse(path)[:2]
        if ((not login_scheme or login_scheme == current_scheme) and
            (not login_netloc or login_netloc == current_netloc)):
            path = request.get_full_path()
        from django.contrib.auth.views import redirect_to_login
        return redirect_to_login(path, login_url, redirect_field_name)
    return wrapped_func

此处settings.MOBILE_LOGIN_URL为/mob/profile/login/，settings.LOGIN_URL为/profile/login/

这里我使用函数django.contrib.auth.decorators.user_passes_test进行相关修改。但我仍然不知道如何重复使用django内置装饰器@login_required。
