所以我试图@login_required在我的不是登录页面的页面上添加一个装饰器，但是当我尝试登录并重定向到另一个页面时，它不会重定向。我得到了我的 url，然后登录，然后它添加了/?next=/redirect_page/. 所以它从www.example.com到www.example.com/?next=/redirect_page/因此，即使它应该看到它已登录并重定向，它也会下面是我的代码。

主页.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>

主页/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})

重定向页面/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})

我究竟做错了什么？

您已经对用户进行了身份验证，但您还没有登录。您需要添加login(request, user)到视图中。

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/')
        ...

有关更多信息，请参阅有关如何登录用户的文档。

请注意，当表单无效时，您不应放入form = SignInForm()块中。else这会将绑定的表单（可能包含有用的错误消息）替换为空表单。

如果您没有LOGIN_URL在设置中指定变量，请这样做。它应该可以发布。
