python - 我在更新空间信息和图像时收到状态代码 300

Question

我一直在尝试更新空间信息以及同一模板上的图像。我可以添加内容，但无法更新。我尝试在提交更新空间信息以更新图像时传递 slug，但是slug 显示为空。我的 ajax 代码和 View 适用于添加部分，但不适用于更新部分。我在 success 函数中打印了 console.log('rent Work') 但在 EditSpaceView 函数中未打印 'request.post' 可能是什么原因？我应该怎么做才能让它发挥作用？

views.py

class EditSpaceView(View):
    def post(self,request,*args,**kwargs):
        print ('edit space view',request)
        if request.POST:
            print('request.post')
            response = HttpResponse('')
            print('edited owner name is',request.POST.get('ownerName'))
            print('edited amenities',request.POST.get('amenities'))
            rental = Rental.objetcs.get(slug=self.kwargs['slug'])
            rental.ownerName = request.POST.get('ownerName')
            rental.email = request.POST.get('email')
            rental.phoneNumber = request.POST.get('phoneNumber')
            rental.listingName = request.POST.get('listingName')
            rental.summary = request.POST.get('summary')
            rental.property = request.POST.get('property')
            rental.room = request.POST.get('room')
            rental.price = request.POST.get('price')
            rental.city = request.POST.get('city')
            rental.place = request.POST.get('place')
            rental.water = request.POST.get('water')
            rental.amenities = request.POST.get('amenities')
            rental.save()
            response['pk-user'] = rental.slug
            #response['pk-user'] = rental.pk
            print('response slug', response);
            return response

        return HttpResponseRedirect('/')

class EditImage(View):
    model = Rental
    template_name = 'rentals/rent_detail.html'
    def get(self, request, *args, **kwargs):
        return render(request, self.template_name)
    def post(self,request,*args,**kwargs):
        try:
            rental = Rental.objects.get(slug = self.kwargs['slug'])
            print('rental slug',rental)
        except Rental.DoesNotExist:
            error_dict = {'message': 'Rental spae not found'}
            return self.render(request,'rentals/rent_detail.html',error_dict)
        if request.FILES:
            for file in request.FILES.getlist('image'):
                print('file',file)
                image = Gallery.objects.create(rental = rental, image=file)
                print('image',image)
        return HttpResponseRedirect('/')

url.py

url(r'^edit/image/(?P<slug>[\w-]+)/$', EditImage.as_view(), name="editImage"),
url(r'^edit/space/(?P<slug>[\w-]+)/$', EditSpaceView.as_view(), name="editSpace"),

ajax代码

$.ajax({
      url:'/edit/space/'+this.props.slug+'/',
      contentType: "application/json",
      data:sendData,
      type:'POST',
      success: function(data, textStatus, xhr ) {
        console.log('rent worked');
        var slug = xhr.getResponseHeader('pk-user');
        console.log('slug',slug);
        $.ajax({
         url:'/edit/image/'+slug+'/',
         data:image,
         contentType:false,
         processData:false,
         type:'POST',
         mimeType: "multipart/form-data",
         success: function(data) {
           console.log('success');
         }
    });
  }
});

Answer 1

[05/Apr/2016 02:58:35] "GET /api/v1/rental/tushant-khatiwada/ HTTP/1.1" 200 963
edit space view <WSGIRequest: POST '/edit/space/tushant-khatiwada/'>
[05/Apr/2016 02:58:50] "POST /edit/space/tushant-khatiwada/ HTTP/1.1" 302 0
[05/Apr/2016 02:58:51] "GET / HTTP/1.1" 200 2363

这些请求表明使用 EditSpaceView 进行编辑的效果符合预期。 300 响应是预期的，并且是由于该 View 末尾的 HttpResponseRedirect("/") 造成的。

请求

[05/Apr/2016 02:58:51] "POST /edit/image/null/ HTTP/1.1" 404 6882

表明您用于构建 ajax 请求 URL 的 slug 无效或为 null。具体检查这一行，

var slug = xhr.getResponseHeader('pk-user');
