我试图让 django 中的消息框架工作。

这是我的 settings.py 中有趣的部分

INSTALLED_APPS = (
    'django.contrib.sessions',
    'django.contrib.messages',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware',
)

我没有添加任何东西TEMPLATE_CONTEXT_PROCESSORS，所以它是默认值。

我的观点，我希望消息显示在哪里：

from django.contrib.messages import get_messages

class ProfileFrontpage(TemplateView):

    def get(self, request, *args, **kwargs):
        if request.user.is_authenticated():

            #Get messages
            messages = get_messages(request)

            #Get the user            
            user = self.request.user

            #Used benefit
            used_benefit_list = Benefit.published.filter(used_benefit__user = user)

            return render(request, "accounts/frontpage.html", {"messages": messages, "used_benefit_list": used_benefit_list})
        else:
            return render(request, 'accounts/not_authenticated.html')

模板：

{% if messages %}
        {% for message in messages %}
            <div class="alert {{ message.tags }}">
                <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>
                {{ message }}
            </div>
        {% endfor %}  
{% endif %}

这是我的表单，当表单有效时应该创建一条消息：

def show_profileform(request):       
    if request.user.is_authenticated():
        user = request.user

        ProfileFormInlineFormSet = inlineformset_factory(User, Profile, form=ProfileForm, can_delete=False)

        if request.method == "POST":
            form = UserForm(request.POST, request.FILES, instance=request.user, prefix="main")
            formset = ProfileFormInlineFormSet(request.POST, request.FILES, instance=request.user, prefix="nested")        
            if 'submit' in request.POST:
                if form.is_valid() and formset.is_valid():

                    u = User.objects.get(username = request.user)                    

                    #Save to database
                    user = form.save()
                    profile = formset.save()

                    messages.success(request, "Settings updated", extra_tags='alert-success')

                    return HttpResponseRedirect('/accounts/')

        else:
            form = UserForm(instance=request.user, prefix="main")
            formset = ProfileFormInlineFormSet(instance=request.user, prefix="nested")

        return render(request, "accounts/form.html", {"form":form, "formset":formset})
    else:
        return render(request, 'accounts/not_authenticated.html')

有谁知道为什么消息不可见？

默认情况下，该TEMPLATE_CONTEXT_PROCESSORS设置包括消息上下文处理器。所以你不需要在你的视图中做。实际上，在您的情况下这是有害的：调用获取消息并清除消息存储。然后，上下文处理器尝试执行相同的操作，但没有找到任何内容，因为您的视图清除了它们。然后它继续在您的模板上下文中设置键并覆盖您视图中的值。get_messages(request)get_messages()messages

简而言之：从您的ProfileFrontpage视图中删除消息处理，它应该可以正常工作。
