运行tellsiteid时出现Django MongoDB Engine错误

Question

所以我根据教程创建了一个django项目和应用程序,我拥有MongoDB引擎所需的所有依赖项,所有这些似乎都工作正常,花花公子直到我尝试启用管理界面.

我取消注释了需求位,并将"django_mongodb_engine"和"djangotoolbox"添加到settings.py中的apps部分

当我尝试进入localhost:8000/admin时出现错误:

"AutoField(默认主键)值必须是表示MongoDB上的ObjectId的字符串(取而代之的是u'1'.请确保您的SITE_ID包含有效的ObjectId字符串."

经过一些谷歌搜索显然我必须运行manage.py tellsiteid并且它会向我吐出我可以在我的settings.py中使用的ID,这将使错误消失,但是当我尝试运行manage.py tellsiteid时,我得到:

Traceback (most recent call last):

Answer 1

您可以创建您的网站,然后获取ID:

python ./manage.py shell

>>> from django.contrib.sites.models import Site
>>> s = Site()
>>> s.save()

然后:

python ./manage.py tellsiteid

Answer 2

如果您不需要该sites功能(非常可能),只需关闭django.contrib.sites应用程序,它将解决与SITE_ID相关的MongoDB问题:

INSTALLED_APPS = (   
    (...)
    # 'django.contrib.sites',  # Comment this out
    (...)
)

Answer 3

您尚未创建任何网站.运行manage.py syncdb以创建一个.
