爲什麼Django-lean測試失敗，因爲沒有找到參數'（）'和關鍵字參數'{}'，因此「NoReverseMatch：Reverse for'opensearch'」。

Question

我很困惑爲什麼我的測試不會通過Django-lean模塊。

Ran 1 test in 1736.834s 

下面是測試： 類ExperimentTagsTest（測試用例）： 網址= 'django_lean.experiments.tests.urls'

def setUp(self): 
    self.experiment = Experiment(name="test_experiment") 
    self.experiment.save() 
    self.experiment.state = Experiment.ENABLED_STATE 
    self.experiment.save() 

    self.other_experiment = Experiment(name="other_test_experiment") 
    self.other_experiment.save() 
    self.other_experiment.state = Experiment.ENABLED_STATE 
    self.other_experiment.save() 
    self.mox = mox.Mox() 


def testIntegrationWithRegisteredUser(self): 
    def create_registered_user_client(i): 
     user = User(username="user%s" % i, email="user%s@example.com" % i) 
     user.set_password("password") 
     user.save() 

     client = Client() 

     if not client.login(username=user.username, password="password"): 
      raise Exception("login failure") 
     return client 
    self.doTestIntegration(
     url=reverse('django_lean.experiments.tests.views.experiment_test', 
        args=[self.experiment.name]), 
     client_factory=create_registered_user_client) 

def doTestIntegration(self, url, client_factory): 
    confirm_human_url = reverse('django_lean.experiments.views.confirm_human') 
    # confirm_human_url set to '/main-app/confirm_human/' during test 
    found_control = False 
    found_test = False 
    for i in range(100): 
     client = client_factory(i) 
     import pdb; pdb.set_trace() 
     response = client.get(confirm_human_url) # this is where the Client can't find the url 
     self.assertEquals(204, response.status_code) 
     response = client.get(url) 
     self.assertEquals(200, response.status_code) 
     in_test = "test" in response.content.lower() 
     in_control = "control" in response.content.lower() 
     self.assertTrue(in_test != in_control) 
     found_control = found_control or in_control 
     found_test = found_test or in_test 

    self.assertTrue(found_control) 
    self.assertTrue(found_test) 

這是視圖，django_lean.experiments.views.confirm_human

@never_cache 
def confirm_human(request): 
    experiment_user = WebUser(request) 
    experiment_user.confirm_human() 
    return HttpResponse(status=204) 

最後，這是從django_lean.experiments.urls URL模式：

urlpatterns = patterns('django_lean.experiments.views', 
    url(r'^goal/(?P<goal_name>.*)$', 'record_experiment_goal'), 
    url(r'^confirm_human/$', 'confirm_human') 
) 

我不明白爲什麼client.get請求不能被跟蹤。

更新在Django-lean源代碼中找不到對opensearch的任何引用。你使用的是Django opensearch插件還是其他一些指向opensearch的應用程序？嘗試在您的項目中搜索opensearch。

原來的答案

乍一看似乎是一個模板是使用{% url %}標籤帶有參數opensearch。至少這是我懷疑基於錯誤跟蹤中的以下行。

File "/usr/local/lib/python2.7/site-packages/Django-1.2.1-py2.7.egg/django/template/__init__.py", line 809, in render_node 
    return node.render(context) 
    File "/usr/local/lib/python2.7/site-packages/Django-1.2.1-py2.7.egg/django/template/defaulttags.py", line 378, in render 
    raise e 

我不熟悉的Django瘦，但我認爲這將是worrh檢查，如果他們有一個名爲opensearch的URL。
