问题描述

标题说明了大部分内容.我在一个教程中的PyCharm中运行Unittests.py，并且我的模板文件夹直接嵌套在我的应用文件夹(superlists/lists/templates/home.html)下方.所以这是我正在运行superlists/lists/tests.py的测试:

The title says most of it. I'm running Unittests.py in PyCharm on a tutorial and my templates folder is nested directly beneath my app folder (superlists/lists/templates/home.html).So here's the test I'm running superlists/lists/tests.py:

def test_home_page_returns_correct_html(self):
    request = HttpRequest()

    response = home_page(request)
    expected_html = render_to_string('home.html')

    self.assertEqual(response.content.decode(), expected_html)

这是正在其上运行的代码(superlists/lists/views.py)

And here's the code it's being run on (superlists/lists/views.py)

def home_page(request):
    return render(request, 'home.html')

这是错误:

   Error
Traceback (most recent call last):
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\utils.py", line 86, in __getitem__
    return self._engines[alias]
KeyError: 'django'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\Me\PycharmProjects\superlists\lists\tests.py", line 19, in test_home_page_returns_correct_html
    response = home_page(request)

    engines = _engine_list(using)

    return engines.all() if using is None else [engines[using]]
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\utils.py", line 110, in all
    return [self[alias] for alias in self]
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\utils.py", line 110, in <listcomp>
    return [self[alias] for alias in self]
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\utils.py", line 101, in __getitem__
    engine = engine_cls(params)
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\backends\django.py", line 31, in __init__
    options['libraries'] = self.get_templatetag_libraries(libraries)
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\backends\django.py", line 49, in get_templatetag_libraries
    libraries = get_installed_libraries()
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\template\backends\django.py", line 121, in get_installed_libraries
    for app_config in apps.get_app_configs())
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\apps\registry.py", line 137, in get_app_configs
    self.check_apps_ready()
  File "C:\Users\Me\AppData\Local\Programs\Python\Python35-32\lib\site-packages\django\apps\registry.py", line 124, in check_apps_ready
    **raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.**

因此，我检查了settings.py中的两个位置:INSTALLED_APPS和TEMPLATES.

So, I checked two places in settings.py, INSTALLED_APPS and TEMPLATES.

这是两个部分:

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

和

    TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

以下是我尝试过的事情的简短列表:
*更改 tests.py 和 views.py 的源代码以具有home.html路径的大多数组合*更改INSTALLED_APPS和TEMPLATES中列出的路径，以使 lists 和 home.html 的路径具有不同长度的大多数组合*将'DIRS':[] 更改为'DIRS':[os.path.join(BASE_DIR，'templates')]，

Here's a short list of things I've tried:
*Changing the source code of tests.py and views.py to have most combinations of the path to home.html*Changing the path listed in INSTALLED_APPS and TEMPLATES to have most combinations of varying lengths to the paths of lists and home.html*Changing 'DIRS': [] to 'DIRS': [os.path.join(BASE_DIR, 'templates')],

旁注:我还不得不反复使用，因为其他解决方案无效，因此，我认识到我的设置可能只是一点点越野车.

Sidenote: I've also had to repeatedly put DJANGO_SETTINGS_MODULE=(project directory name).settings as an environment variable in PyCharm, using the solution to an error, here, because the other solutions didn't work, so, I recognize that my setup may be just a tad buggy.
