Question

我正在尝试将导出按钮合并到我的Django管理站点中。能够在管理员中显示按钮，但每次单击按钮时它都会中断，我收到以下错误：

NoReverseMatch at / admin / emarshalapp / attorney / export / Reverse for ＆＃39; app_list＆＃39;参数＆＃39;（）＆＃39;和关键字参数＆＃39; {＆＃39; app_label＆＃39;：＆＃39;＆＃39;}＆＃39;未找到。尝试过1种模式： [＆＃39;管理/（？Pfiler | emarshalapp | AUTH）/ $＆＃39;]

如果有帮助，这里是the full traceback。

我正在尝试按照this tutorial来执行导出逻辑，但我显然必须做错事，只是不确定是什么。我已经在SO（包括this answer）和其他地方尝试过针对NoReverseMatch推荐的所有解决方案，但是看不到任何修复。我很难过，请帮忙！

添加按钮的change-list.html模板部分：

{% block object-tools-items %}

    {{ block.super }}

    <li>
        <a href="export/"
           class="grp-state-focus addlink">Export</a>
    </li>

{% endblock %}

这是我的INSTALLED_APPS设置：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    # my apps here
    'emarshalapp',
    'localflavor',
    'simple_history',
    'easy_thumbnails',
    'filer',
    'mptt',
    'PIL',
    'django_extensions',

]

admin.py：

def my_view(self, request):
        # custom view which should return an HttpResponse
        if request.method == 'POST':
            if 'export' in request.POST:
                response = HttpResponse(
                    content_type='application/vnd.ms-excel')
                response['Content-Disposition'] = \
                    'attachment; filename=Report.xlsx'
                xlsx_data = WriteToExcel(attorney_range, attorney)
                response.write(xlsx_data)
                return response
        else:
            return render(request, "change_list.html",
                          context_instance=RequestContext(request))

def get_urls(self):
    urls = super(AttorneyAdmin, self).get_urls()
    my_urls = patterns('', url(r'^export/$', self.my_view, name='export/'))
    return my_urls + urls

views.py:

def attorney_history(request):
    attorney_range = Attorney.objects.all().filter(active=True)
    attorney = None
    if request.method == 'POST':
        if 'export' in request.POST:
            response = HttpResponse(content_type='application/vnd.ms-excel')
            response['Content-Disposition'] = \
                'attachment; filename=Report.xlsx'
            xlsx_data = WriteToExcel(attorney_range, attorney)
            response.write(xlsx_data)
            return HttpResponseRedirect('%s/export/' % reverse('export/'))
    else:
        return render("change_list.html",
                      context_instance=RequestContext(request))

urls.py：

app_name = 'emarshalapp'
...
    def get_urls(self):
        urls = super(AttorneyAdmin, self).get_urls()
        my_urls = url(r"^export/$",
                      name='export/')
        return my_urls + urls

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

然后根据教程我有一个excel_utils.py：

def WriteToExcel(attorney_range, attorney=None):
    output = StringIO.StringIO()
    workbook = xlsxwriter.Workbook(output)
    worksheet_s = workbook.add_worksheet("Summary")
[code to add excel data]

我的律师管理员班级：

@admin.register(Attorney)
class AttorneyAdmin(SimpleHistoryAdmin):
    change_list_template = 'change_list.html'

    def my_view(self, request):
        # custom view which should return an HttpResponse
        if request.method == 'POST':
            if 'export' in request.POST:
                response = HttpResponse(
                    content_type='application/vnd.ms-excel')
                response['Content-Disposition'] = \
                    'attachment; filename=Report.xlsx'
                xlsx_data = WriteToExcel(attorney_range, attorney)
                response.write(xlsx_data)
                return response
        else:
            return render(request, "change_list.html",
                          context_instance=RequestContext(request))
    fieldsets = (...)
    list_display = (...)
    inlines = (...)
    search_fields = (...)
    list_filter = (...)

URL上的NoReverseMatch，模板渲染期间的错误等
