我在我的ansible剧本中有这个剧本
- name: Setup virtualenv
pip:
requirements="/vagrant/webapp/requirements/{{ requirements_filename }}"
virtualenv="$HOME/.envs/{{ project_name }}"
但是,我收到一个Permission denied错误.似乎ansible试图将软件包安装到系统路径而不是virtualenv.
这是完整的追溯:

控制台刚才说,
django.core.management.base.CommandError:系统检查发现了一些问题:
错误::(admin.E202)'api4android.Friends'对'api4android.User'有多个ForeignKey.
这是代码
class Friends(models.Model):
user = models.ForeignKey(User, null=True, related_name='user')
friend = models.ForeignKey(User, null=True, related_name='friend')
note_name = models.CharField(max_length=20)
def __str__(self):
return self.note_name
希望我可怜的英语让你理解我的意思.
我正在尝试做一个简单的查询,但我得到了 'Manager' object is not iterable error.
我的代码(相关部分):
def sort(request):
sort_type = request.GET.get('srt', '')
q = Question.objects
if sort_type == 'views':
q.order_by('-views')
q.all()
return render(request, 'questions/index.html',{
'questions': q
})
我究竟做错了什么？
我按照这里的指示:http: //django-oscar.readthedocs.org/en/latest/internals/getting_started.html
