Question

我刚刚将我的第一个django应用程序部署到了Heroku平台。我基本上遵循this tutorial，而不是创建一个虚拟的django-admin.py startproject hellodjango . django应用程序，我使用了我的应用程序，目前可以在我的Windows PC上运行。部署应用程序并在heroku上运行服务器时，我得到No module named theme.urls。

这是追溯。有什么想法吗？

Answer 1

主项目的urls.py设置错误，这是我可以从异常跟踪中推断出来的。请在主项目urls.py中使用下面提到的内容。

(r'^home/', include('MAINPROJECT_NAME.APPNAME.urls'))

Answer 2

所以我发现错误是heroku在名为'app'而不是'theme'的文件夹中创建了应用程序。我尝试使用

通过heroku CLI重命名应用程序

heroku apps:rename theme

但由于某些原因我无法弄清楚，它给出了You do not have access to appname错误。所以我只是将我的代码的每个部分都改为app.foo。它起作用了。

Answer 3

在我看来，你已经错误地命名了一些东西。查看ROOT_URLCONF和INSTALLED_APPS：

ROOT_URLCONF = 'theme.urls'
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    #'registration',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    'django.contrib.admindocs',
    'themes',
    'haystack',
)

您的INSTALLED_APPS说themes s，但您的ROOT_URLCONF说theme而没有s。尝试让它们同步..

没有名为theme.urls的模块
