我一直在扩展以下项目：jquery 文件上传表单&我只想在名为 admin 的列中显示数据库中值为 1 的项目。

有人能告诉我如何修改以下基于类的视图以仅显示符合上述要求的图像吗？

class PictureCreateView(CreateView):
    model = Picture

    def form_valid(self, form):
        self.object = form.save()
        f = self.request.FILES.get('file')
        data = [{'url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'thumbnail_url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'delete_url': reverse('upload-delete', args=[self.object.id]), 'delete_type': "DELETE"}]
        response = JSONResponse(data, {}, response_mimetype(self.request))
        response['Content-Disposition'] = 'inline; filename=files.json'
        return response

    def get_context_data(self, **kwargs):
        context = super(PictureCreateView, self).get_context_data(**kwargs)
        context['pictures'] = Picture.objects.all()
        return context

在我看来，这就像一个非常基本的 Django 问题，我建议你了解它是如何工作的。

class PictureCreateView(CreateView):
    model = Picture

    def form_valid(self, form):
        self.object = form.save()
        f = self.request.FILES.get('file')
        data = [{'url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'thumbnail_url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'delete_url': reverse('upload-delete', args=[self.object.id]), 'delete_type': "DELETE"}]
        response = JSONResponse(data, {}, response_mimetype(self.request))
        response['Content-Disposition'] = 'inline; filename=files.json'
        return response

    def get_context_data(self, **kwargs):
        context = super(PictureCreateView, self).get_context_data(**kwargs)
        # Change the all to some filter
        context['pictures'] = Picture.objects.filter(admin=1)
        return context
