python - 这个装饰器如何调用 'register' 方法？

Question

我想了解装饰器@not_authenticated 中发生了什么。TraceRoute 的下一步是方法 'register'，它也位于 django_authopenid/views.py 中，我只是不明白，因为我什至没有看到 register 中提到的任何地方登录()

如何调用“register”方法？

def not_authenticated(func):  
    """ decorator that redirect user to next page if he is already logged."""  
    def decorated(request, *args, **kwargs):  
        if request.user.is_authenticated():  
            next = request.GET.get("next", "/")  
            return HttpResponseRedirect(next)  
        return func(request, *args, **kwargs)  
    return decorated  

@not_authenticated  
def signin(request,newquestion=False,newanswer=False):  
    """  
    signin page. It manage the legacy authentification (user/password)   
    and authentification with openid.  

    url: /signin/  

    template : authopenid/signin.htm  
    """  
    request.encoding = 'UTF-8'  
    on_failure = signin_failure  
    next = clean_next(request.GET.get('next'))  

    form_signin = OpenidSigninForm(initial={'next':next})  
    form_auth = OpenidAuthForm(initial={'next':next})  

    if request.POST:     

        if 'bsignin' in request.POST.keys() or 'openid_username' in request.POST.keys():  

            form_signin = OpenidSigninForm(request.POST)  
            if form_signin.is_valid():  
                next = clean_next(form_signin.cleaned_data.get('next'))  
                sreg_req = sreg.SRegRequest(optional=['nickname', 'email'])  
                redirect_to = "%s%s?%s" % (  
                        get_url_host(request),

                        on_failure=signin_failure,   
                        sreg_request=sreg_req)  

        elif 'blogin' in request.POST.keys():  
            # perform normal django authentification  
            form_auth = OpenidAuthForm(request.POST)  
            if form_auth.is_valid():  
                user_ = form_auth.get_user()  
                login(request, user_)  
                next = clean_next(form_auth.cleaned_data.get('next'))  
                return HttpResponseRedirect(next)  

    question = None  
    if newquestion == True:  
        from forum.models import AnonymousQuestion as AQ  
        session_key = request.session.session_key  
        qlist = AQ.objects.filter(session_key=session_key).order_by('-added_at')  
        if len(qlist) > 0:  
            question = qlist[0]  
    answer = None  
    if newanswer == True:  
        from forum.models import AnonymousAnswer as AA  
        session_key = request.session.session_key  
        alist = AA.objects.filter(session_key=session_key).order_by('-added_at')  
        if len(alist) > 0:  
            answer = alist[0]  

    return render('authopenid/signin.html', {  
        'question':question,  
        'answer':answer,  
        'form1': form_auth,  
        'form2': form_signin,  
        'msg':  request.GET.get('msg',''),  
        'sendpw_url': reverse('user_sendpw'),  
    }, context_instance=RequestContext(request))  

查看请求，似乎 account/register/确实使用 'PATH_INFO': u'/account/register/' 引用了 register 方法

请求如下:

如果不尝试理解所有这些，你为什么不插入:

import pdb; pdb.set_trace()

这个“注册”方法在哪里？

比打“bt”
