Question

启动服务器时，错误崩溃，我应注意哪个文件和一段代码？该网站上提供的其他答案无济于事。

端子：

group_by_sub_category = 
VAR sub_category_wise_total = 
GROUPBY (  
    percentage_subcategory,
    percentage_subcategory[YearMonth],
    percentage_subcategory[PercentRange],
    "sum_sub1",
        SUMX(
            CURRENTGROUP()
            , 
            IF(
                percentage_subcategory[SubCategory] = "Sub1",
                percentage_subcategory[TotalCount],
                BLANK()
            )
        )
    ,
    "sum_sub2",
        SUMX(
            CURRENTGROUP()
            , 
            IF(
                percentage_subcategory[SubCategory] = "Sub2",
                percentage_subcategory[TotalCount],
                BLANK()
            )
        )
    ,
    "sum_total_count", SUMX(CURRENTGROUP(), percentage_subcategory[TotalCount])
) 

RETURN
SELECTCOLUMNS (
    sub_category_wise_total,
    "YearMonth",percentage_subcategory[YearMonth],
    "PercentRange",percentage_subcategory[PercentRange],
    "sum_sub1",[sum_sub1],
    "sum_sub2",[sum_sub2],
    "sum_total_count", [sum_total_count],
    "sub1_percentage",([sum_sub1]/[sum_total_count]),
    "sub2_percentage",([sum_sub2]/[sum_total_count]) 
)

接下来是我的应用程序代码。

主要urls.py

  File "/home/lab/ProjectsDjango/env_bookmarks/dj-bookmarks/bookmarks/account/urls.py", line 7, in <module>
    url(r'^login/$', 'django.contrib.auth.views.login', name='login'),
  File "/home/lab/ProjectsDjango/env_bookmarks/bookmarks/lib/python3.8/site-packages/django/conf/urls/__init__.py", line 22, in url
    return re_path(regex, view, kwargs, name)
  File "/home/lab/ProjectsDjango/env_bookmarks/bookmarks/lib/python3.8/site-packages/django/urls/conf.py", line 73, in _path
    raise TypeError('view must be a callable or a list/tuple in the case of include().')
TypeError: view must be a callable or a list/tuple in the case of include().

应用查看次数。py

from django.conf.urls import include, url
from django.contrib import admin



urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^account/', include('account.urls')),
    ]

应用urls.py

from django.http import HttpResponse
from django.shortcuts import render
from django.contrib.auth import authenticate, login
from .forms import LoginForm
from django.contrib.auth.decorators import login_required


def user_login(request):
    if request.method == 'POST':
        form = LoginForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = authenticate(username=cd['username'], password=cd['password'])
            if user is not None:
                if user.is_active:
                    login(request, user)
                    return HttpResponse('Authenticated successfully')
                else:
                    return HttpResponse('Disabled account')
            else:
                return HttpResponse('Invalid login')
    else:
        form = LoginForm()
    return render(request, 'account/login.html', {'form': form})

@login_required 
def dashboard(request):
    return render(request, 'account/dashboard.html', {'section': 'dashboard'})

也许我在错误的地方找东西，并试图在不存在的地方找到错误？

我假设您正在使用django> 1.9：您不能将字符串用作视图。因此，您需要对所有视图执行以下操作：

from django.contrib.auth import login, logout

urlpatterns = [

    url(r'^login/$', login, name='login'),
    url(r'^logout/$', logout, name='logout'),
    ......

]

如何解决此错误？您要注意什么？
