@login_required得到下一個

Question

我目前無法獲得@login_required重定向的next值，原因有很多。我重視我的代碼爲login.html的頁面，我的項目設置

輸入name=nextvalue=''而它應該包含從{{ next }}這是在調試轉儲顯示爲值：

GET data 
Variable Value 
u'next' [u'/accounts/profile/'] 

login.html：

{% extends "base.html" %} 

{% block content %} 

    {% if form.errors %} 
    <p class="error"> Sorry, you have entered an incorrect username or password</p> 
    {% endif %} 
    <form action="/accounts/auth/" method="post">{% csrf_token %} 
    <label for="username">User name:</label> 
    <input type="text" name="username" value="" id="username"> 

    <label for="password">Password:</label> 
    <input type="password" name="password" value="" id="password"> 

    <input type='text' name="next" value="{{ next }}"> 
    <input type="submit" value="login"> 
    </form> 

{% endblock %}

views.py：

    c={} 
    c.update(csrf(request)) 
    return render_to_response('login.html', c) 

Answer 1

嘗試添加next參數對上下文。

def login(request): 
    c = {'next' : request.GET.get('next', '/')} 
    return render(request, 'login.html', c) 

一對夫婦在這裏附加說明：

1. 你可能想使用render快捷方式或提供RequestContext爲context_instance參數傳送給render_to_response電話。

2. Django的內建login視圖應該爲你處理這個，除非你需要特殊的邏輯。編寫自己的視圖沒有什麼問題，但是Django提供了很多功能，以減少自己編寫代碼的數量。內建的意見也具有經過良好測試和通用的好處。

Answer 2

我最終做的是以下內容。對我來說，這似乎是一個黑客工作。有沒有更好的方式使用csrf登錄？

views：

def login(request): 
    c={} 
    c.update(csrf(request)) 
    if 'next' in request.GET: 
    c['next'] = request.GET.get('next') 
    return render_to_response('login.html', c) 

def auth_view(request): 
    username = request.POST.get('username', '') 
    password = request.POST.get('password', '') 
    user = auth.authenticate(username=username, password=password) 

    if user is not None: 
    auth.login(request, user) 

    if request.POST.get('next') != '': 
     return HttpResponseRedirect(request.POST.get('next')) 
    else: 
     return HttpResponseRedirect('/accounts/loggedin') 
    else: 
    return HttpResponseRedirect('/accounts/invalid') 

login.html：

<input type="hidden" name="next" value="{{ next }}"/>
