需要Django登錄名，無法正確重定向

Question

因此，我嘗試在不是登錄頁面的頁面上添加@login_required裝飾器，但是當我嘗試登錄並重定向到其他頁面時，它不會重定向。 我進入我的網址，然后登錄，然后添加/?next=/redirect_page/ 。 因此，它應該從www.example.com轉到www.example.com/?next=/redirect_page/ ，盡管它應該看到它已登錄並重定向，而不添加下一部分。 下面是我的代碼。

home.html：

<form method="post" class="form-signin" action="{% url 'index' %}">
    {% csrf_token %}
    <input type="hidden" name="next" value="{{ next }}" />
    <h2 class="form-signin-heading">Please Sign In</h2>
    {% bootstrap_form form %}
    {% buttons %}
    <button type="submit" class="btn btn-primary">Submit</button>
    {% endbuttons %}
</form>

home / views.py：

from django.shortcuts import render
from django.http import HttpResponseRedirect
from django.contrib.auth import authenticate

from .forms import SignInForm


def index(request):
    # if this is a POST request we need to process the form data
    if request.method == 'POST':
        # create a form instance and populate it with data from the request:
        form = SignInForm(request.POST)
        # check whether it's valid:
        if form.is_valid():
            # process the data in form.cleaned_data as required
            user = authenticate(username=request.POST.get('username', None), password=request.POST.get('password', None))
            if user is not None:
                return HttpResponseRedirect('/redirect_page/')
            else:
                form = SignInForm()

    # if a GET (or any other method) we'll create a blank form
    else:
        form = SignInForm()

    return render(request, "home/home.html", {'form': form})

redirect_page / views.py：

from django.shortcuts import get_object_or_404, render
from django.contrib.auth.decorators import login_required

from .models import Table


@login_required
def index(request):
    stuff = Table.objects.all()
    context = {"stuff": stuff,}
    return render(request, "redirect_page/index.html", context)


@login_required
def stuff(request, stuff_id):
    stuff = get_object_or_404(Table, pk=word_id)
    return render(request, "redirect_page/detail.html", {"stuff": stuff})

我究竟做錯了什么？

Answer 1

您已經對用戶進行了身份驗證，但尚未登錄。您需要在視圖中添加login(request, user) 。

from django.contrib.auth import authenticate, login

def index(request):
    ...
    if form.is_valid():
        # process the data in form.cleaned_data as required
        user = authenticate(username=request.POST.get('username', None), password=request.POST.get('password', None))
        if user is not None:
            login(request, user)
            return HttpResponseRedirect('/redirect_page/')
        ...

有關更多信息，請參閱有關如何登錄用戶的文檔。

請注意，當表單無效時，不應將form = SignInForm()放在else塊中。 這會將綁定形式（可能包含有用的錯誤消息）替換為空形式。

如果您未在設置中指定LOGIN_URL變量，請這樣做。 它應該工作。
