需要 Django 登录未正确重定向

Question

所以我想在我的非登录页面的页面上添加一个 @login_required 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。我进入 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/ 即使它应该看到它已登录并重定向，而不是添加下一部分。下面是我的代码。

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})

我做错了什么？

Answer 1

如果您没有在设置中指定 LOGIN_URL 变量，请执行此操作。它应该工作 post 那。

Answer 2

您已对用户进行身份验证，但尚未登录。您需要将 login(request, user) 添加到视图中。

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/')
        ...

有关详细信息，请参阅 how to log a user in 上的文档。

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