Question

我一直试图找出我在django 1.8.3中创建的代码的内容......当我使用django的测试运行器时（更具体地说是命令：{ {1}}）我总是收到相同的错误消息：

文件＆＃34; C：\ Users \ dimitris \ djangop \ oursite \ predsite \ tests.py＆＃34;，第117行，在test_long_list中 self.assertTrue（＆＃39;分页＆＃39;在response.content中） AssertionError：False不正确

以下是我详细创建的代码：
的 OURSITE（项目）＆GT;＆GT; PREDSITE（APP）＆GT;＆GT; MODELS.PY：

python manage.py test predsite

OURSITE＆GT;＆GT; PREDSITE＆GT;＆GT; VIEWS.PY ：

from django.db import models
from django.contrib.auth.models import User
import os


def hashed_uploads_dirs(instance, filename):
    """Returns path with md5 hash as directory"""
    return os.path.join(instance.md5, filename)

class Datafile(models.Model):
    file_id = models.IntegerField(default=0, primary_key=True)
    datafile = models.FileField(upload_to='.')
    user = models.ForeignKey(User, default=1)
    md5 = models.CharField(max_length=32)

OURSITE＆GT;＆GT; OURSITE＆GT;＆GT; URLS.PY

class FileListView(ListView):

   model = Datafile
   queryset = Datafile.objects.order_by('-file_id')
   context_object_name = "files"
   template_name = "index.html"
   paginate_by = 5


class FileAddView(FormView):

   form_class = DatafileForm
   success_url = reverse_lazy('home')
   template_name = "add.html"


   def form_valid(self, form):
      form.save(commit=True)
      messages.success(self.request, 'File uploaded!', fail_silently=True)
      return super(FileAddView, self).form_valid(form)


class FileAddHashedView(FormView):
     """This view hashes the file contents using md5"""

   form_class = DatafileForm
   success_url = reverse_lazy('home')
   template_name = "add.html"

   def form_valid(self, form):
    hash_value = hashlib.md5(form.files.get('datafile').read()).hexdigest()
    # form.save returns a new Datafile as instance
    instance = form.save(commit=False)
    instance.md5 = hash_value
    instance.save()
    messages.success(
        self.request, 'File hashed and uploaded!', fail_silently=True)
    return super(FileAddHashedView, self).form_valid(form)

OURSITE＆GT;＆GT; PREDSITE＆GT;＆GT; CONTEXT_PROCESSORS.PY

urlpatterns = patterns('',
     url(r'^add/$', FileAddView.as_view(), name='datafile-add'),
     url(r'^add/files/$', FileListView.as_view(), name='home'),
) + static(settings.MEDIA_URL, datafile_root=settings.MEDIA_ROOT)

OURSITE＆GT;＆GT; PREDSITE＆GT;＆GT; FORMS.PY

from django.conf import settings


def static_root(request):
    """
    Adds static-root context variables to the context.

    """
    return {'STATIC_ROOT': settings.STATIC_ROOT}


def media_root(request):
   """
   Adds media-root context variables to the context.

   """
   return {'MEDIA_ROOT': settings.MEDIA_ROOT}

OURSITE＆gt;＆gt; PREDSITE＆gt;＆gt; TESTS.PY （我提供错误发生的部分）

class DatafileForm(forms.ModelForm):
    """Upload files with this form"""
    class Meta:
       model = Datafile
       exclude = ('md5',)

现在重要的模板如下：的 OURSITE＆GT;＆GT; TEMPLATES＆GT;＆GT; index.html的

＆＃13;

def test_long_list(self):
    """Get a paginated home page"""
    filename = "./file_{}.txt"
    for x in xrange(10):
        fb = Datafile(datafile=filename.format(x))
        fb.save()
    response = self.client.get(reverse('home'))
    self.assertEqual(response.status_code, 200)
    self.assertTrue('pagination' in response.content)
    self.assertEqual(
        len(response.context['files']),
        FileListView.paginate_by)

＆＃13;

因为很明显有一个名为＆＃34; pagination＆＃34;在上面的模板中，我怎么可能在执行测试运行器时收到此错误消息？

非常感谢，提前!!

这是因为div data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource : Episodes.Data.itemsBindingList.dataSource }"></div>的{{1}}属性返回了上下文变量，不是 "{\"exception\":null,\"error\":{\"description\":\"It's not possible to obtain the property 'dataSource' of undifined or null reference\"代码。相反，如果这是您的目标，您可以测试context列表中您要查找的项目。

请尝试使用assertContains。文档中的语法表明您可能希望将以下内容添加到测试中：

response

AssertionError：False不正确（Django版本1.8.3）
