我有一个名为Question的模型.模型允许用户创建新问题.我正在尝试使用对象的查询集填充多个表单.当我尝试使用查询集初始化时出现问题.我收到这个错误

 'Question' object is not iterable


File "C:\mysite\pet\views.py" in DisplayAll
294.             formset = form(initial=q)

models.py

class Question(models.Model):
    question= models.CharField(max_length=500)
    user = models.ForeignKey(User)

形式

class QuestionForm(forms.ModelForm):
question= forms.CharField(required=True,max_length=51)
class Meta:
    model = Question
    fields = ('question',)

意见

def DisplayAll(request):
    q = Question.objects.filter(user=request.user)

    form = formset_factory(QuestionForm)
    formset = form(initial=q)
    return render(request,'question.html',{'formset':formset})

模板

 {% for f in formset %}
 {{f}}
 {% endfor %}

我正在尝试建立一个由django + uwsgi + ngnix组成的生产服务器.我正在关注的教程位于http://www.panta.info/blog/3/how-to-install-and-configure-nginx-uwsgi-and-django-on-ubuntu.html

生产服务器正在运行,因为我可以在调试打开时看到管理页面,但是当我关闭调试时.它再次显示服务器错误(500).我不知道该怎么办 .Ngnix应该服务于django请求.我现在很无能为力,请有人帮助我.

我有一个简单的应用程序，允许您将图像上传到服务器，它设置在我的生产服务器上，由 django + uwsgi + ngnix 组成。

尝试上传图像时遇到问题。我收到以下错误：

错误

502 Bad Gateway
nginx/1.2.1

功能：

def upload(request):
    form = ImageForm()
    context = {'form':form,}
    context.update(csrf(request))


    if request.POST:
        form = ImageForm(request.POST, request.FILES)
        if form_is.valid():

            image = request.FILES.get('image')
            CarPhoto.objects.create(user=request.user,cars=1,description='dwq',image=image)
            return HttpResponseRedirect(reverse('transformer:kevin'))
    return     render_to_response('image.html',context,context_instance=RequestContext(request))

模板

 <form method="POST" enctype="multipart/form-data" action=".">

 <div id="c">image</div> {{form.image}}
