urls.py

urlpatterns += patterns('beenthere.views', 
    #beenthere urls 
    (r'^$','index'), 
    (r'^home2/$','category'), 
    (r'^accounts/login/$','login_user'),

    ) 

疑問

我怎麼想重定向到相同的URL從哪個請求發送，我嘗試使用request.path，但它將我重定向到/ accounts/login/url，這是不希望的。

你需要做的是什麼跟蹤引薦是當你顯示的登錄表單，可能在存儲的用戶會話的值，然後將用戶重定向回該網址後，他們已經成功登錄。

東西：

def login_user(request): 
    if request.POST: 
     sform = LoginForm(request.POST) 
     rform = UserForm() 
     if sform.is_valid(): 
      username = request.POST.get('username') 
      password = request.POST.get('password') 
      user = authenticate(username = username,password = password) 
      if user is not None: 
       if user.is_active: 
        login(request,user) 
        return redirect(request.path) 
       else: 
        state = "Your account is not active." 
        #or first set the user to is active and then log in 
        return redirect(req.session['after_login_url'],user = user) 
       return render_to_response('home.html',{'state':state,'user':user},context_instance = RequestContext(request)) 
      else: 
       state = "Incorrect Username or Password" 
       #sform = LoginForm() 
       form = LoginForm() 
       return render_to_response('register.html',{'state':state,'sform':sform,'rform':rform,'form':form},context_instance = RequestContext(request)) 
     else: 
      state = "Invalid form" 
      dLoginForm = LoginForm() 
      rform = PartialSignupForm() 
      return render_to_response('register.html',{'sform':sform,'rform':rform,'form':form},context_instance = RequestContext(request)) 
    else: 
     dLoginForm = LoginForm() 
     rform = PartialSignupForm() 
     req.session['after_login_url'] = req.META.get('HTTP_REFERER') 
     return render_to_response('category.html',{'dLoginForm':dLoginForm,'rform':rform},context_instance = RequestContext(request)) 

當然，你也應該補充檢查，以確保該HTTP_REFERER頭存在，並確保after_login_url鍵存在（並可能有一個健全的價值，如果外部網站直接鏈接到您的登錄頁面或類似鏈接），並且如果有任何這些測試失敗，請安全回退l（就像用戶的個人資料頁面或您的網站索引頁面一樣）。
