之前已经问过这个问题，但给出的答案似乎对我不起作用......我有：

ValueError at /myapp/
dictionary update sequence element #0 has length 1; 2 is required

Error during template rendering

In template ~/Software/myproject/myapp/templates/myapp/base.html, error at line 53
dictionary update sequence element #0 has length 1; 2 is required

base.html

<a class="brand" href="{% url "about" %}">About page</a>

错误

 File "~/Software/myproject/myapp/views/basic.py", line 380, in idx_order
    return render(request, 'myapp/index_other.html', {'orders': orders, 'orders_done': orders_done, 'STATUS_CHOICES': dSTATUS_CHOICES})

视图.py

def idx_order(request):
    orders = Order.objects.all().order_by('status','deadline','created','lastUpdate').exclude(status=2)
    orders_done = Order.objects.all().order_by('status','deadline','created','lastUpdate').filter(status=2)

    return render(request, 'myapp/index_other.html', {
        'orders': orders, 
        'orders_done': orders_done, 
        'STATUS_CHOICES': dSTATUS_CHOICES
        })

def about(request):
    """
    Function outputs user and system credentials to an about.html page depending on whether DEBUG = True/False. 
    """
    if settings.DEBUG == True:
        do stuff

        return render(request, 'myapp/about.html', 
            {'list_zero': list_zero,
                'list_one': list_one, 
                'installed_packages_list': library_dict
            })
    else:    
        return HttpResponse("You shouldn't be here :o)")

网址.py

urlpatterns = [
    url(r'^$', idx_order, name='idx_order'),
    url(r'^about/$', about, name='about'),

我正在执行从 Django1.8 到 1.11 的更新。我为此绞尽脑汁，但看不出我的错误在哪里。
