Question

运行manage.py测试时，收到以下错误。

======================================================================
ERROR: Failure: RuntimeError (Model class app.pipeline.models.Product doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.)

RuntimeError: Model class app.pipeline.models.Product doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

settings.py

INSTALLED_APPS = [
    'pipeline.apps.PipelineConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_nose',
    'bootstrap3',
    'bootstrap_pagination',
    'mobilereports',
    'rest_framework',
    'api'
]

此错误仅在我运行测试时被抛出，但不会以任何方式影响网站的性能（现在正在生产中）。

此项目是继承的，项目或应用程序名称可能先前已更改（不确定错误是否与此相关）。

此错误消息的原因很可能与您将__init__.py与manage.py放在同一文件夹中有关。如果您删除了__init__.py，那么测试跑步者就不会再抱怨了。

在这里添加这个，因为我在寻找问题的答案时遇到了这个问题。

为什么我在django unittest中收到有关应用名称的错误？
